What does the PFC do?
The prefrontal cortex (PFC) plays a central role in cognitive control functions, and dopamine in the PFC modulates cognitive control, thereby influencing attention, impulse inhibition, prospective memory, and cognitive flexibility.
What is a granular cortex?
the portion of the cerebral cortex that contains granule cells, which are located in layers II and IV of the cortex (see cortical layers). The term refers particularly to primary sensory cortex, in which layer IV (the major input area) is very thick.
What happens when the prefrontal cortex is damaged?
A person with damage to the prefrontal cortex might have blunted emotional responses, for instance. They might even become more aggressive and irritable, and struggle to initiate activities. Finally, they might perform poorly on tasks that require long-term planning and impulse inhibition.

Can you improve your prefrontal cortex?
How to Strengthen Your Prefrontal Cortex. Games: Word games, memory games, and puzzles are effective ways to strengthen your prefrontal cortex. Learning: Learning something new, like a language, instrument, or other skill, is even more effective than word games at enhancing your prefrontal cortex.

Keratinocytes migrating from the underlying stratum spinosum become known as granular cells in this layer. These cells contain keratohyalin granules, which are filled with histidine- and cysteine-rich proteins that appear to bind the keratin filaments together.
What does granular mean in medical terms?
Granulation: That part of the healing process in which lumpy, pink tissue containing new connective tissue and capillaries forms around the edges of a wound. Granulation of a wound is normal and desirable.
