The medial pFC (mPFC) is frequently reported to play a central role in Theory of Mind (ToM). However, the contribution of this large cortical region in ToM is not well understood. Combining a novel behavioral task with fMRI, we sought to demonstrate functional divisions between dorsal and rostral mPFC. All conditions of the task required the representation of mental states (beliefs and desires)...

Medial prefrontal cortex (mPFC) is known to be involved in relapse after cocaine withdrawal, but the underlying cellular mechanism remains largely unknown. Here, we report that after terminating repeated cocaine exposure in rats, a gradual increase in the expression of brain-derived neurotrophic factor (BDNF) in the mPFC facilitates activity-induced long-term potentiation (LTP) of excitatory sy...

There has been considerable interest in the importance of oscillations in the brain and in how these oscillations relate to the firing of single neurons. Recently a number of studies have shown that the spiking of individual neurons in the medial prefrontal cortex (mPFC) become entrained to the hippocampal (HPC) theta rhythm. We recently showed that theta-entrained mPFC cells lost theta-entrain...

The model predictive flux control (MPFC) strategy is an improved method for the weighting factor that difficult to adjust in traditional torque (MPTC). By analyzing relationship among torque, stator and load angle, simultaneous of amplitude converted into equivalent references vector, which eliminates directly factor. However, MPFC also suffers from high ripples if only one voltage vector appli...

the purpose of the present study was to determine the role of medial prefrontal cortex (mpfc) dopaminergic system in fear conditioning response considering individual differences. animals were initially counterbalanced and classified based on open field test, and then were given a single infusion of the dopamine agonist, amphetamine (amph) and antagonist, clozapine (clz) into the medial prefron...

Much data suggests that hippocampal-medial prefrontal cortex (mPFC) interactions support memory consolidation. This process is thought to involve the gradual transfer of transient hippocampal-dependent memories to distributed neocortical sites for long-term storage. However, hippocampal projections to the neocortex involve a multisynaptic pathway that sequentially progresses through the entorhi...

Homer postsynaptic scaffolding proteins regulate forebrain glutamate transmission and thus, are likely molecular candidates mediating hypofrontality in addiction. Protracted withdrawal from cocaine experience increases the relative expression of Homer2 versus Homer1 isoforms within medial prefrontal cortex (mPFC). Thus, this study used virus-mediated gene transfer strategies to investigate the ...

Post-traumatic stress disorder (PTSD) is a significant problem that may affect individuals who have been exposed to a traumatic event or events, including combat, violent crime or childhood abuse. The medial prefrontal cortex (mPFC) is known to be significantly involved in emotional adjustment, particularly introspection, amygdala inhibition and e...

A key process for recognition memory is the formation of associations between an object and the place in which it was encountered, a process that has been shown to require the perirhinal (PRH) and medial prefrontal (mPFC) cortices. Here we demonstrate, for the first time, the importance of glutamatergic neurotransmission, within the PRH and mPFC, for object-in-place associative recognition memo...

In adult animals, the medial prefrontal cortex (mPFC) plays a significant role in regulating emotions and projects to the amygdala and periaqueductal gray (PAG) to modulate emotional responses. However, little is known about the development of this neural circuit and its relevance to unlearned fear in pre-adulthood. To address these issues, we examined the mPFC of 14-d-old (infants), 26-d-old (...
