Hippocampus: What It Is, Function, Location & Damage - Cleveland Clinic
2024年5月14日 · The hippocampus is a part of your limbic system and is connected to the hypothalamus and amygdala. These structures help regulate various bodily functions, including the “fight-or-flight” response.
Functional specialization and interaction in the amygdala-hippocampus ...
2023年5月22日 · Here, we simultaneously recorded intracranial EEG from the amygdala and hippocampus of epilepsy patients while performing a WM task, and compared their representation patterns during the...
From Structure to Behavior in Basolateral Amygdala-Hippocampus …
2017年10月30日 · Here, we briefly introduce the anatomy and functions of amygdala and hippocampus, and then present behavioral, electrophysiological, optogenetic and biochemical evidence from recent studies to illustrate how amygdala and hippocampus work synergistically to form long-term memory.
Amygdala-hippocampus dynamic interaction in relation to memory
The amygdala is the most notably involved brain structure in emotional responses and the formation of emotional memories. In this review we describe a system, composed of the amygdala and the hippocampus, that acts synergistically to form long-term memories of significantly emotional events.
2021年5月10日 · humans indicate that the amygdala modulates memory consolidation and plasticity processes in the hippo-campus, the anatomical pathways through which the amygdala affects hippocampal regions that are important for episodic memories were unresolved until recent optogenetic advances made it possible to visualize and
Amygdala-hippocampal interactions in synaptic plasticity and …
The ability of emotional arousal to influence memory consolidation appears to depend heavily on the amygdala and, in the case of declarative-like memories, its interactions with the hippocampal system. This review will describe how the amygdala and hippocampus act synergistically to create and strengthen the consolidation of these memories. 1.1.
From Structure to Behavior in Basolateral Amygdala-Hippocampus Circuits
2017年10月31日 · The amygdala is specialized for input and processing of emotion, while the hippocampus is essential for declarative or episodic memory. During emotional reactions, these two brain regions interact to translate the emotion …
Functional Neuroanatomy of Amygdalohippocampal …
Although there are neuropathological changes (neurofibrillary tangles and amyloid plaques) in all cortical areas, the density of atrophic neurons exhibiting neurofibrillary tangles is far greater in the medial temporal lobe, including the amygdala, hippocampus, and parahippocampal cortices (Van Hoesen et al., 1986; Arnold et al., 1991; Poulin ...
Limbic System: Hippocampus (Section 4, Chapter 5 ... - Texas …
The hippocampus has direct connections to the entorhinal cortex (via the subiculum) and the amygdala. These structures connect to many other areas of the brain. The entorhinal cortex projects to the cingulate cortex. Therefore, the hippocampus can affect the cingulate cortex through the anterior thalamic nucleus or the entorhinal cortex.
Stress Effects on Neuronal Structure: Hippocampus, Amygdala, …
The trisynaptic organization of the hippocampus showing input from the entorhinal cortex to both CA3 and dentate gyrus (DG), with feed forward and feedback connections between these two regions that promotes memory formation in space and time, but at the same time, makes the CA3 vulnerable to seizure-induced excitation (McEwen, 1999).Chronic stress causes apical dendrites of CA3 neurons to ...
