Input from the ventral hippocampus to the medial prefrontal cortex regulates social memory in wild type mice and atypically-strengthened input causes social memory dysfunction in Rett syndrome mice.
The well-established link between stress and depression could be due to the activity of a population of cells in prefrontal cortex that express a gene mutated in the rare disorder Wolfram syndrome.
Retrieval practice strongly engages the medial prefrontal cortex to integrate and differentiate memory representations, resulting in more effective memory updating.
A striking dissociation exists in the medial prefrontal cortex, with different brain regions responding to value when commitments are deferred to the future and when prospects are judged to be undesirable.
When the fear-enhancing effects of prior exposure to stress are absent, the expression of fear reflects normal neural activity in the medial prefrontal cortex, not stress-induced hyperactivity in the amygdala.
Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.
