Successful interaction with the external world requires choosing appropriate actions in the context of available choices. Such decisions require the evaluation of the reward magnitude, or value, associated with each potential ...

It has been assumed that Ca2+ influx of different duration and amplitude would generate different level of potentiation. The conventional protocols of generating LTP have been 1. tetanic stimulation of presynaptic cell, ...

Despite decades of evidence for functional plasticity in the adult brain, the role of structural plasticity in its manifestation remains unclear. cpg15 is an activity-regulated gene encoding a membrane-bound ligand that ...

The basal ganglia, and specifically the sensorimotor (dorsolateral) striatum, have been implicated in stimulus-response learning. Here, I analyze the role the striatum plays in learning. We recorded from neurons of the ...

(cont.) increased activity whenever recollection was attempted, independent of the level of recollection success. The results are consistent with the hypothesis that increased left-lateralized retrieval activity in older ...

(cont.) baseline, and that some coherence-based approaches best predict the human data. However, coherence-based algorithms that operate on trees did not perform as well as coherence-based algorithms that operate on more ...

Perceptual systems are specialized for transducing and interpreting information from the environment. But perceptual systems can also be used for processing information that arises from other sources, such as mental imagery ...
