Reward acts as a signal to control delay-period activity in delayed-response tasks.

abstract：:Regional variation in the distribution of SP and NFT within the brain is well documented. Consideration of such variation is potentially of help in formulating models of disease progression. Several models propose that pathological changes in Alzheimer's disease (AD) progress in a step-wise fashion along neuronally co...
