Petrovich GD, Holland PC, Gallagher M. Amygdalar and prefrontal pathways to the lateral hypothalamus are activated by a learned cue that stimulates eating.
Recent interest in the lateral habenula stems from an elegant experiment by Matsumoto and colleagues using monkeys which showed that neurons in the lateral habenula are activated by non-reward predicting stimuli and inhibited by reward-predicting stimuli [63].
Within rostral PFC, a lateral subregion was activated by analogy task both during study of the source (before the source could be compared with a target) and when the target appeared.
Concomitantly, DELTA-1 activates by lateral inhibition NOTCH signalling (as indicated by Hes5 expression) in the neighbouring NP cells of the PNTZ, which remain proliferating (self-replicating).
Left medial and lateral OFC were shown to be common areas for feedback processing, whereas left ventral striatum and left lateral OFC were specifically activated by reward and punishment, respectively.
The study was designed to investigate the neurocognitive network in the frontal and lateral temporal cortices that is activated by the complex cognitive visuomotor tasks of letter writing.
