Some Brain Cells 'Change Channels' To Fine-tune The Message

...s are most common in these particular cells in the cerebellum (so-called stellate cells). But Huganir thinks the channel changing is going to be relatively common in the brain.

For example, though the cerebrum and the cerebellum are two distinct parts of the brain, located apart from each other and doing very different jobs, their gene expression profiles reflected their commonality as part of the nervous system.
