Final exam week.
The neocortex is composed, broadly, of two types of neurons: excitatory and inhibitory. Neocortical inhibition is often treated as a uni-dimensional force that, in a graded fashion, limits the firing of excitatory cells. However, inhibition is more complex in at least two ways. First, there are multiple distinct subtypes of inhibitory neurons which, based on their morphological and physiological properties, are likely to play very different roles in neocortical function. Second, levels of inhibition can fluctuate rapidly, on the order of tens of milliseconds, and can regulate the firing of excitatory cells on this time scale. These two complexities of inhibitory function will be discussed in the contexts of sensory processing and seizure control.
