Ventral striatal neurons encode the value of the chosen action in rats deciding between differently delayed or sized rewards.

19 Oct 2009 The ventral striatum (VS) is thought to serve as a gateway whereby associative information from the amygdala and prefrontal regions can influence motor output to guide behavior. If VS mediates this "limbic-motor" interface, then one might expect ... Read more...

Single-trial phase precession in the hippocampus.

19 Oct 2009 During the crossing of the place field of a pyramidal cell in the rat hippocampus, the firing phase of the cell decreases with respect to the local theta rhythm. This phase precession is usually studied on the basis of data in which many place field ... Read more...

Analgesia accompanying food consumption requires ingestion of hedonic foods.

12 Oct 2009 Animals eat rather than react to moderate pain. Here, we examined the behavioral, hedonic, and neural requirements for ingestion analgesia in ad libitum fed rats. Noxious heat-evoked withdrawals were similarly suppressed during self-initiated ... Read more...

Technical information about 'Conditioning, Operant'

Definition: Learning situations in which the sequence responses of the subject are instrumental in producing reinforcement. When the correct response occurs, which involves the selection from among a repertoire of responses, the subject is immediately reinforced.
