Hippocampal microtubule-associated protein-2 alterations with contextual memory.

abstract：:Auditory transients (such as sound onset or a frequency transition within a continuous sound) are assumed to parse the auditory input into smaller units enabling the formation of unitary sound representations separately for each segment. This was discovered by using the mismatch negativity (MMN) component of the event...
