By looking at
activation of different brain regions while test subjects were exposed to different listening conditions, Dr. Johnsrude's research has revealed that the early processing of sound, which occurs in a brain region called the primary auditory cortex, depends on higher - level linguistic knowledge encoded in other regions of the brain.
Dr. Ressler's group uses well - established mouse models to examine different aspects of fear learning and investigate the
role of different brain regions, in particular the amygdala, in fear processing.
With MRI technology — especially the type known as functional MRI (or fMRI)-- the
activity of different brain regions can be viewed during an event, such as viewing pictures, computing sums or listening to music.
Wilder Penfield was the first neurosurgeon to explore the neural locus of epilepsy at the same time as mapping behavioral / memory
functions of different brain regions through electrical stimulation in fully conscious patients.
The results showed that the
size of these different brain regions — especially one specific area where they intersect and communicate with each other, known as the midcingulate cortex — was correlated with better memory.
