The interhemispheric amygdala-accumbens circuit encodes
Using anatomical tract tracing, selective lesions, optogenetics, photometry, and calcium imaging combined with behavioral assays, Tian et al. investigated the contributions to behavior of the projections from the basolateral amygdala (BLA) to the contralateral nucleus accumbens (NAc).
Mapping effective connectivity of human amygdala subdivisions …
2022年8月20日 · Here we present results from 25 neurosurgical patients who had concurrent electrical stimulation of the amygdala with intracranial electroencephalography (electrical stimulation tract-tracing;...
The structural and functional connectivity of the amygdala: …
Based on the extensive anatomical connections between the amygdala and mPFC shown in human and non-human primates, a number of investigations have used these functional and effective connectivity measures to assess the strength of amygdala-mPFC coupling and its relationship with behavioral outcomes [9, 34, 35].
Organizational principles of amygdalar input-output neuronal circuits ...
2021年8月16日 · Using a simplified cell-type- and projection-specific retrograde transsynaptic tracing technique, we scrutinized brain-wide afferent inputs of four major output neuronal groups in the amygdalar...
From circuits to behaviour in the amygdala | Nature
2015年1月14日 · With recent technological advances that allow for causal investigations of specific neural circuit elements, we can now begin to map the complex anatomical connections of the amygdala onto...
Amygdala function in emotion, cognition, and behavior
2022年1月1日 · The amygdala is highly responsive to salient signals that are fundamental in social behavior among conspecifics, through its rich interconnections with prefrontal and temporal lobe structures, as well as other subcortical regions (e.g., striatum) involved in decision-making (discussed later).
Amygdala ensembles encode behavioral states | Science - AAAS
2019年4月19日 · Our study reveals two large, nonoverlapping functional neuronal ensembles of the basal amygdala representing internal states. The ensembles are anatomically intermingled and encode opposing moment-to-moment states changes, especially regarding exploratory and defensive behaviors, but do not provide a scalar measure of global anxiety levels.
Amygdala Intercalated Cells: Gate Keepers and Conveyors of …
2022年12月7日 · Information flow within the amygdala is regulated by the intercalated cells (ITCs), which are densely packed clusters of GABAergic neurons that encircle the basolateral amygdala (BLA) and provide contextually relevant feedforward inhibition of amygdala nuclei, including the central and BLA.
Amygdala Intercalated Cells: Gate Keepers and Conveyors of
2022年12月7日 · Information flow within the amygdala is regulated by the intercalated cells (ITCs), which are densely packed clusters of GABAergic neurons that encircle the basolateral amygdala (BLA) and provide contextually relevant feedforward inhibition of amygdala nuclei, including the central and BLA.
Amygdala-hippocampal interactions in synaptic plasticity and …
2021年10月1日 · We review research investigating how the amygdala modulates memories of emotional experiences. The amygdala influences memory consolidation and related molecular changes in the hippocampus. The amygdala modulates hippocampal memory via projections to the medial entorhinal cortex.
