Webb20 dec. 2012 · We further suggest that rapidly acquired input-output mappings in mPFC are initially supported by the hippocampus but later become independent. This framework unifies the known representational capabilities of mPFC with its role in a broad range of memory studies. The mPFC Predicts Adaptive Responses WebbThe medial prefrontal cortex (mPFC) provides top-down regulatory control of fear responding, receiving input from the hippocampus and thalamus and projecting to the amygdala to modulate fear behavior on the basis of complex environmental information. 10 Overall, these findings support involvement of thalamus, amygdala, dACC, …

Webb1 apr. 2024 · The ventral/intermediate hippocampus directly innervates the mPFC via monosynaptic projections. Silencing the axon terminals of these projections in the mPFC disrupted spatial learning and coupling between learning-associated SWRs, slow oscillations, and spindles (Binder et al., 2024). Webb6 apr. 2024 · In contrast, the information flow between the ventral hippocampus and mPFC is important for spatial working memory, fear learning, and anxiety-related behaviors (49–51), and amygdala-mPFC synaptic interactions have been implicated in regulation of emotional process, stress, fear learning, and anxiety-related behaviors (52–54).
