Prefrontal-Hippocampal Interactions in Memory and Emotion
The hippocampal formation (HPC) and medial prefrontal cortex (mPFC) have well-established roles in memory encoding and retrieval. However, the mechanisms underlying interactions between the HPC and mPFC in achieving these functions is not fully understood. Considerable research supports the idea that a direct pathway from the HPC and subiculum to the mPFC is critically involved in cognitive and...
متن کاملWorking Memory Performance Correlates with Prefrontal-Hippocampal Theta Interactions but not with Prefrontal Neuron Firing Rates
Performance of memory tasks is impaired by lesions to either the medial prefrontal cortex (mPFC) or the hippocampus (HPC); although how these two areas contribute to successful performance is not well understood. mPFC unit activity is temporally affected by hippocampal-theta oscillations, with almost half the mPFC population entrained to theta in behaving animals, pointing to theta interactions...
متن کامل[Hippocampal-prefrontal cortical circuit and working memory].
The study on learning and memory is one of the striking subjects in neuroscience today. In the cerebral cortex, it is has been proved that, the hippocampus, the prefrontal cortex and the hippocampal-prefrontal cortical circuit are important to working memory. In this paper, we review findings of the anatomical and electrophysiological characteristics of the hippocampal-prefrontal cortical circu...
متن کاملDynamic adjustments in prefrontal, hippocampal, and inferior temporal interactions with increasing visual working memory load.
The maintenance of visual stimuli across a delay interval in working memory tasks is thought to involve reverberant neural communication between the prefrontal cortex and posterior visual association areas. Recent studies suggest that the hippocampus might also contribute to this retention process, presumably via reciprocal interactions with visual regions. To characterize the nature of these i...
متن کاملHippocampal-Prefrontal Theta Oscillations Support Memory Integration
Integration of separate memories forms the basis of inferential reasoning--an essential cognitive process that enables complex behavior. Considerable evidence suggests that both hippocampus and medial prefrontal cortex (mPFC) play a crucial role in memory integration. Although previous studies indicate that theta oscillations facilitate memory processes, the electrophysiological mechanisms unde...
