The amygdala as a neurobiological target for ghrelin in rats: neuroanatomical, electrophysiological and behavioral evidence. [PDF]

PLoS ONE, 2012
Here, we sought to demonstrate that the orexigenic circulating hormone, ghrelin, is able to exert neurobiological effects (including those linked to feeding control) at the level of the amygdala, involving neuroanatomical, electrophysiological and ...

Hypothalamus and amygdala functional connectivity at rest in narcolepsy type 1

NeuroImage: Clinical, 2021
Introduction: functional and structural MRI studies suggest that the orexin (hypocretin) deficiency in the dorso-lateral hypothalamus of narcoleptic patients would influence both brain metabolism and perfusion and would cause reduction in cortical grey ...

Dopamine Induces a Slow Afterdepolarization in Lateral Amygdala Neurons [PDF]

Journal of Neurophysiology, 2007
The amygdala and dopaminergic innervation thereunto are considered to cooperatively regulate emotional states and behaviors. The present experiments examined effects of dopamine on lateral amygdala (LA) neuron excitability by whole cell recordings. Bath application of dopamine induced slow afterdepolarization (sADP).

Insecure attachment during infancy predicts greater amygdala volumes in early adulthood [PDF]

, 2014
Background The quality of the early environment is hypothesized to be an influence on morphological development in key neural areas related to affective responding, but direct evidence to support this possibility is limited.

Sex Differences in the Role of Neurexin 3α in Zoster Associated Pain

Frontiers in Integrative Neuroscience, 2022
Varicella zoster virus (VZV) induces orofacial pain and female rats show greater pain than male rats. During the proestrus phase of the estrous cycle the VZV induce pain response is attenuated in female rats.

Hemispheric Lateralization of Pain Processing by Amygdala Neurons

Journal of Neurophysiology, 2009
Recent biochemical and behavioral data suggest right-hemispheric lateralization of amygdala functions in pain. Our previous electrophysiological studies showed pain-related neuroplasticity in the latero-capsular division of the central nucleus of the amygdala (CeLC) in the right brain hemisphere. Here we determined differences in the processing of pain-

Beta-adrenergic receptors in the lateral nucleus of the amygdala contribute to the acquisition but not the consolidation of auditory fear conditioning

Frontiers in Behavioral Neuroscience, 2010
Beta-adrenergic receptors (βARs) have long been associated with fear disorders and with learning and memory. However, the contribution of these receptors to Pavlovian fear conditioning, a leading behavioral model for studying fear learning and ...

Sex Differences in CGRP Regulation and Function in the Amygdala in a Rat Model of Neuropathic Pain

Frontiers in Molecular Neuroscience, 2022
The amygdala has emerged as a key player in the emotional response to pain and pain modulation. The lateral and capsular regions of the central nucleus of the amygdala (CeA) represent the “nociceptive amygdala” due to their high content of neurons that ...

Myosin light chain kinase regulates synaptic plasticity and fear learning in the lateral amygdala

, 2006
Learning and memory depend on signaling mole- cules that affect synaptic efficacy. The cytoskeleton has been implicated in regulating synaptic transmission but its role in learning and memory is poorly understood.

Response properties of human amygdala subregions : evidence based on functional MRI combined with probabilistic anatomical maps [PDF]

, 2007
The human amygdala is thought to play a pivotal role in the processing of emotionally significant sensory information. The major subdivisions of the human amygdala—the laterobasal group (LB), the superficial group (SF), and the centromedial group (CM ...
