Functional connectivity of intercalated nucleus with medial amygdala: A circuit relevant for chemosignal processing

IBRO Neuroscience Reports, 2022
Medial amygdala processes social/reproductive chemosensory input, and its projections to preoptic and hypothalamic areas evoke appropriate behavioral and physiological responses.

Astrocytes in the Amygdala

The FASEB Journal, 2010
The amygdala is connected to numerous brain regions and is involved in complex behaviors such as survival and reproduction. This highly conserved brain region is sexually dimorphic in several species with the most dramatic differences found in the medial subregion.

Increased Inhibition of the Amygdala by the mPFC may Reflect a Resilience Factor in Post-traumatic Stress Disorder: A Resting-State fMRI Granger Causality Analysis

Frontiers in Psychiatry, 2018
Purpose: To determine whether effective connectivity of the amygdala is altered in traumatized subjects with and without post-traumatic stress disorder (PTSD).Materials and Methods: Resting-state functional MRI data were obtained for 27 patients with ...

Differential activation of anatomically defined neuronal subpopulations in the amygdala during fear conditioning and extinction [PDF]

, 2009
The amygdala is a key structure of the neuronal circuitry mediating expression and extinction of conditioned fear. However, fear memories are thought to be encoded in a larger network comprising the medial prefrontal cortex (mPFC) and the ...

Peripherally-administered amphetamine induces plasticity in medial prefrontal cortex and nucleus accumbens in rats with amygdala lesions: implications for neural models of memory modulation

Frontiers in Behavioral Neuroscience, 2023
The amygdala has been implicated in a variety of functions linked to emotions. One popular view is that the amygdala modulates consolidation in other brain systems thought to be mainly involved in learning and memory processes. This series of experiments

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]

, 2009
Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

The Corticomedial Amygdala and Learning in an Agonistic Situation in the Rat [PDF]

, 1984
Social agonistic behaviour of intact male rats is strongly reduced by the experience of defeat by a dominant male conspecific. Small electrolytic lesions in the corticomedial amygdala strongly affected this behavioural change due to defeat. No effects of

Central amygdala micro-circuits mediate fear extinction [PDF]

, 2021
The central amygdala inhibitory microcircuits mediate fear extinction by reversible, stimulus- and context-specific changes in neuronal responses. These alterations are absent when extinction is deficient and selective silencing of PKCδ neurons impairs ...
