The final stages of this sequence are caused by blood accumulation that forces the temporal lobe medially, with resultant compression of the third cranial nerve and eventually the brain stem.

Sleep affects almost every type of tissue and system in the body, from the brain and heart to the immune system and mood.

The scientists were astonished by the results: selective noradrenaline release re-wired the connectivity patterns between different brain regions in a way that was extremely similar to the changes observed in humans exposed to acute stress. Networks that process sensory stimuli, such as the visual and auditory center of the brain, exhibited the strongest increase in activity. A similar rise in activity was observed in the amygdala network, which is associated with states of anxiety.

Psychopathy is a personality disorder characterized by ‘a lack of empathy and remorse, shallow affect, glibness, manipulation and callousness.’ When individuals with psychopathy imagine others in pain, researchers have found that brain areas necessary for feeling empathy and concern for others fail to become active and connected to other important regions involved in affective processing and compassionate decision-making.

When you are in an agreeable and comfortable situation it is more difficult to empathize with another person’s suffering. At a neurobiological level – without a properly functioning supramarginal gyrus – your brain has a tough time putting itself in someone else’s shoes.

The right supramarginal gyrus ensures that we can decouple our perception of ourselves from that of others. When the neurons in this part of the brain were disrupted in the course of a research task, the participants found it difficult to stop from projecting their own feelings and circumstances onto others. The participants' assessments were also less accurate when they were forced to make particularly quick decisions.

In a study published in the Journal of Neuroscience on October 9, 2013, Max Planck researchers identified that the tendency to be egocentric is innate for human beings – but that a part of your brain recognizes a lack of empathy and autocorrects. This specific part of your brain is called the the right supramarginal gyrus. When this brain region doesn't function properly—or when we have to make particularly quick decisions—the researchers found one’s ability for empathy is dramatically reduced. This area of the brain helps us to distinguish our own emotional state from that of other people and is responsible for empathy and compassion.

“It is not that something different is seen, but that one sees differently. It is as though the spatial act of seeing were changed by a new dimension. —Carl Jung”

“trauma produces actual physiological changes, including a recalibration of the brain’s alarm system, an increase in stress hormone activity, and alterations in the system that filters relevant information from irrelevant”

“Sadly, our educational system, as well as many of the methods that profess to treat trauma, tend to bypass this emotional-engagement system and focus instead on recruiting the cognitive capacities of the mind. Despite the well-documented effects of anger, fear, and anxiety on the ability to reason, many programs continue to ignore the need to engage the safety system of the brain before trying to promote new ways of thinking. The last things that should be cut from school schedules are chorus, physical education, recess, and anything else involving movement, play, and joyful engagement.”

“We have learned that trauma is not just an event that took place sometime in the past; it is also the imprint left by that experience on mind, brain, and body. This imprint has ongoing consequences for how the human organism manages to survive in the present. Trauma results in a fundamental reorganization of the way mind and brain manage perceptions. It changes not only how we think and what we think about, but also our very capacity to think.”

“Neuroscience research shows that the only way we can change the way we feel is by becoming aware of our inner experience and learning to befriend what is going inside ourselves.”

Trauma victims cannot recover until they become familiar with and befriend the sensations in their bodies. Being frightened means that you live in a body that is always on guard. Angry people live in angry bodies. The bodies of child-abuse victims are tense and defensive until they find a way to relax and feel safe. In order to change, people need to become aware of their sensations and the way that their bodies interact with the world around them. Physical self-awareness is the first step in releasing the tyranny of the past.

“As long as you keep secrets and suppress information, you are fundamentally at war with yourself…The critical issue is allowing yourself to know what you know. That takes an enormous amount of courage.”

Thalamus: Our Thalamus is like a cook.  It takes in info from all the senses and then blends it with our autobiographical memory. Breakdown of the thalamus explains why trauma is primarily remembered not as a story with a beginning, middle, or end, but as isolated sensory imprints: images, sounds, physical sensations that are accompanied by intense emotions usually terror and helplessness. In normal circumstances, the thalamus also acts as a filter or gatekeeper. This makes it a central component of attention, concentration, and new learning—all of which are compromised by trauma. People with PTSD have their floodgates wide open. Lacking a filter, they are on constant sensory overload. In order to cope, they try to shut themselves down and develop tunnel vision and hyperfocus. If they can’t shut down naturally, they may enlist drugs or alcohol to block out the world. The tragedy is that the price of closing down includes filtering out sources of pleasure and joy as well.

All of us, but especially children, need … confidence that others will know, affirm, and cherish us. Without that we can’t develop a sense of agency that will enable us to assert: “This is what I believe in; this is what I stand for; this is what I will devote myself to.” As long as we feel safely held in the hearts and minds of the people who love us, we will climb mountains and cross deserts and stay up all night to finish projects. Children and adults will do anything for people they trust and whose opinion they value. But if we feel abandoned, worthless, or invisible, nothing seems to matter. Fear destroys curiosity and playfulness. In order to have a healthy society we must raise children who can safely play and learn. There can be no growth without curiosity and no adaptability without being able to explore, through trial and error, who you are and what matters to you.

The challenge of recovery is to reestablish ownership of your body and your mind — of your self. This means feeling free to know what you know and to feel what you feel without becoming overwhelmed, enraged, ashamed, or collapsed. For most people this involves (1) finding a way to become calm and focused, (2) learning to maintain that calm in response to images, thoughts, sounds, or physical sensations that remind you of the past, (3) finding a way to be fully alive in the present and engaged with the people around you, (4) not having to keep secrets from yourself, including secrets about the ways that you have managed to survive

If a mother cannot meet her baby’s impulses and needs, “the baby learns to become the mother’s idea of what the baby is.” Having to discount its inner sensations, and trying to adjust to its caregiver’s needs, means the child perceives that “something is wrong” with the way it is. Children who lack physical attunement are vulnerable to shutting down the direct feedback from their bodies, the seat of pleasure, purpose, and direction. […] The need for attachment never lessens. Most human beings simply cannot tolerate being disengaged from others for any length of time. People who cannot connect through work, friendships, or family usually find other ways of bonding, as through illnesses, lawsuits, or family feuds. Anything is preferable to that godforsaken sense of irrelevance and alienation.

Securely attached kids learn the difference between situations they can control and situations where they need help. They learn that they can play an active role when faced with difficult situations. In contrast, children with histories of abuse and neglect learn that their terror, pleading, and crying do not register with their caregiver. Nothing they can do or say stops the beating or brings attention and help. In effect they’re being conditioned to give up when they face challenges later in life.

Agency starts with what scientists call interoception, our awareness of our subtle sensory, body-based feelings: the greater that awareness, the greater our potential to control our lives. Knowing what we feel is the first step to knowing why we feel that way. If we are aware of the constant changes in our inner and outer environment, we can mobilize to manage them.

When our senses become muffled, we no longer feel fully alive. […] In response to the trauma itself, and in coping with the dread that persisted long afterward, these patients had learned to shut down the brain areas that transmit the visceral feelings and emotions that accompany and define terror. Yet in everyday life, those same brain areas are responsible for registering the entire range of emotions and sensations that form the foundation of our self-awareness, our sense of who we are. What we witnessed here was a tragic adaptation: In an effort to shut off terrifying sensations, they also deadened their capacity to feel fully alive.

The body keeps the score: If the memory of trauma is encoded in the viscera, in heartbreaking and gut-wrenching emotions, in autoimmune disorders and skeletal/muscular problems, and if mind/brain/visceral communication is the royal road to emotion regulation, this demands a radical shift in our therapeutic assumptions.

Despite the well-documented effects of anger, fear, and anxiety on the ability to reason, many programs continue to ignore the need to engage the safety system of the brain before trying to promote new ways of thinking. The last things that should be cut from school schedules are chorus, physical education, recess, and anything else involving movement, play, and joyful engagement. When children are oppositional, defensive, numbed out, or enraged, it’s also important to recognize that such “bad behavior” may repeat action patterns that were established to survive serious threats, even if they are intensely upsetting or off-putting.

The brain-disease model overlooks four fundamental truths: (1) our capacity to destroy one another is matched by our capacity to heal one another. Restoring relationships and community is central to restoring well-being; (2) language gives us the power to change ourselves and others by communicating our experiences, helping us to define what we know, and finding a common sense of meaning; (3) we have the ability to regulate our own physiology, including some of the so-called involuntary functions of the body and brain, through such basic activities as breathing, moving, and touching; and (4) we can change social conditions to create environments in which children and adults can feel safe and where they can thrive.

Social support is not the same as merely being in the presence of others. The critical issue is reciprocity: being truly heard and seen by the people around us, feeling that we are held in someone else’s mind and heart. For our physiology to calm down, heal, and grow we need a visceral feeling of safety. No doctor can write a prescription for friendship and love: These are complex and hard-earned capacities. You don’t need a history of trauma to feel self-conscious and even panicked at a party with strangers — but trauma can turn the whole world into a gathering of aliens.

In trauma survivors, Van der Kolk notes, the parts of the brain that have evolved to monitor for danger remain overactivated and even the slightest sign of danger, real or misperceived, can trigger an acute stress response accompanied by intense unpleasant emotions and overwhelming sensations. Such posttraumatic reactions make it difficult for survivors to connect with other people, since closeness often triggers the sense of danger. And yet the very thing we come to most dread after experiencing trauma — close contact with other people — is also the thing we most need in order to regain psychoemotional solidity and begin healing.

This, he points out, is why we’ve evolved a refined mechanism for detecting danger — we’re incredibly attuned to even the subtlest emotional shifts in those around us and, even if we don’t always heed these intuitive readings, we can read another person’s friendliness or hostility on the basis of such imperceptible cues as brow tension, lip curvature, and body angles.

In pathological mixing multilingual patients mix two or more languages within a single utterance, whereas in pathological switching patients alternate utterances in one language to utterances in another, even when the interlocutor cannot understand one of the two languages. Numerous studies have established that pathological mixing is mainly due to lesions in the parietotemporal structures of the left hemisphere, whereas the nervous structures responsible for switching between languages have not yet been clearly described.5 6 The study of the bilingual patient reported here has allowed us to establish—for the first time—the role of anterior brain structures in the switching mechanism in multilingual subjects.

The prevailing approaches to reading instruction in American schools are inconsistent with basic things scientists have discovered about how children learn to read. Many educators don't know the science, and in some cases actively resist it. The resistance is the result of beliefs about reading that have been deeply held in the educational establishment for decades, even though those beliefs have been proven wrong by scientists over and over again.

During improvisation, the highly trained music majors used their brains in a way the nonmusicians could not: they deactivated their right-temporoparietal junction. Normally, the r-TPJ reads incoming stimuli, sorting the stream for relevance. By turning that off, the musicians blocked out all distraction. They hit an extra gear of concentration, allowing them to work with the notes and create music spontaneously.

To understand exactly what should be done requires first understanding the new story emerging from neuroscience. The lore of pop psychology is that creativity occurs on the right side of the brain. But we now know that if you tried to be creative using only the right side of your brain, it’d be like living with ideas perpetually at the tip of your tongue, just beyond reach.When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions.Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with.Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.

Scientists studying the brain have discovered that the organ operates on up to 11 different dimensions, creating multiverse-like structures that are “a world we had never imagined.”

Just a few interconnected neurons (a microcircuit) can perform sophisticated tasks such as mediate reflexes, process sensory information, generate locomotion and mediate learning and memory.  More complex networks (macrocircuits) consist of multiple imbedded microcircuits.  Macrocircuits mediate higher brain functions such as object recognition and cognition.  So, multiple levels of networks are ubiquitous in the nervous system.  Networks are also prevalent within neurons.  These nanocircuits constitute the underlying biochemical machinery for mediating key neuronal properties such as learning and memory and the genesis of neuronal rhythmicity.
