Long term potentiation (LTP) of synaptic transmission at the CA3-CA1 hippocampal synapse is a model synaptic plasticity mechanism that may underlie hippocampal dependent learning and memory. Inhibition of post-synaptic ...

The ability to group stimuli into meaningful categories is a fundamental cognitive process though little is known its neuronal basis. To address this issue, we trained monkeys to perform a categorization task in which they ...

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 ...
