    5. voxel

      A value on a regular grid in three-dimensional space. In this case, composes the 3-dimensional brain image.

    6. T2*-sensitive functional imag-ing

      MR imaging frequency that displays CSF as the brightest contrast, white matter as the second brightest contrast, and gray matter as the third brightest contrast. Stronger than T2 MR imaging frequency.

    7. 3-T Siemens Trio MRI scan-ner

      3 Tesla-powered scanner model. In our replication, we will be using a different scanner.

    9. inter stimulus intervals

      The amount of time between the end of one stimulus being presented and the start of another stimulus being presented.

    10. T1-weighted images

    11. cerebellum

      Structure at the lower back of the brain, associated with motor control.

    12. cortex
