if you lose a finger in an accident, that you will have children missing a finger, and that such changes will eventually become characteristics of the species
Many years ago, I can probably understand how people would have this theory. But reading this now, it seems like a silly thought to think that characteristic modifications will pass along to the offspring.

as the environment changes, new traits may evolve
I wonder if some species are being forced to gain adaptive traits due to climate change affecting their environment.

. Understanding evolution can give us fresh insights about our psychology and the psychology of other species
With the capability to understand other species, we are able to see how we are connected to them.

The patient must be enclosed in a metal tube-like device for the duration of the scan, sometimes as long as thirty minutes
This must be agonizing for patients who need an MRI scan but are afraid of confined spaces or have discomfort with loud noises.

it exposes patients to a dose of radiation many times higher than that of X-rays
The thought of CT scanning emitting more radiation than x-rays is alarming. Especially to a patient who needs multiple CT scans.

more modern medical imaging technologies produce data that are integrated and analyzed by computers to produce three-dimensional (3D) images or images that reveal aspects of the body functioning.
It amazes me how computers have been upgraded to do so much more than expected since the first modern computer.

to visualize the parts of the brain that respond when we're exposed to stimuli that upset us or make us happy.
After reading this section, I can now see how important functional imaging techniques are, especially to people with psychiatric disorders.

The more neuroscientific research progresses, the more clearly it is established that human behavior and mental processes—the key interests for psychological study—are intimately intertwined with activity in the brain.
With the research of neuroscience, biopsychologist will be able to form a relation between human behavior and mental processes with the brain.

the frontal lobes were considered silent structures, without function and unrelated to human behavior.
Frontal lobes were not correlated to our behavior but after Gage's accident, it was shown how important our frontal lobes impact and influence our behavior.

He further explained that "humidity" inside the head contributed to mood changes and when this moisture inside the brain goes beyond limits, the brain loses control over its rationality and mental disorders appear
I've heard how physical humidity in the weather can have an impact on your mood, but never heard about humidity in the brain causing mental disorders to appear. That is an interesting thought....

The Organization of Behavior, where he introduced the first comprehensive theory on how the brain might create and control complex psychological functioning
