LTP in the lateral amygdala during cocaine withdrawal

European Journal of Neuroscience, 2005
AbstractThe amygdala plays key roles in several aspects of addiction to drugs of abuse. This brain structure has been implicated in behaviours that reflect drug reward, drug seeking, and the aversive effects of drug withdrawal. Using a model that involves repeated cocaine injections to approximate ‘binge’ intoxication, we show in rats that during ...

Amygdala fMRI lateralizes temporal lobe epilepsy

Neurology, 2006
To characterize the clinical value of an fMRI task activating the amygdala in controls and patients with mesial temporal lobe epilepsy (MTLE).A fearful face fMRI paradigm using video sequences was developed and investigated in 17 patients with epilepsy (12 had MTLE [6 right- and 6 left-sided]) and 17 healthy control subjects.

Localization and connectivity of the lateral amygdala in anuran amphibians

Journal of Comparative Neurology, 2004
AbstractOn the basis of chemoarchitecture and gene expression patterns in the amphibian amygdaloid complex, new subdivisions have been proposed and compared with their counterparts in amniotes. Thus, a portion of the ventral pallium of anurans has been tentatively named “lateral amygdala” (LA) and compared with the basolateral complex of mammals.

Fear conditioning is associated with synaptogenesis in the lateral amygdala

Synapse, 2010
AbstractFear conditioning in the rat typically involves pairing a conditioned stimulus (tone) with an aversive unconditioned stimulus (foot shock) which elicits a freeze response. Although the circuitry that underlies this form of learning is well defined, potential synaptic changes associated with this form of learning have not been fully investigated.

Opioid actions on neurons of rat lateral amygdala in vitro

Brain Research, 1993
Intracellular recordings were made from neurons in the lateral nucleus of the amygdala, in a slice of rat brain that was superfused in vitro. [Met5]enkephalin (3-30 microM) and the mu receptor selective agonist DAMGO (Tyr-D-Ala-Gly-MePhe-Gly-ol; 0.3-3 microM) hyperpolarized about 50% of cells; this was blocked by naloxone and by the mu receptor ...

GABAergic Interneurons in the Mouse Lateral Amygdala: A Classification Study

Journal of Neurophysiology, 2010
Whole cell patch-clamp recordings were performed in GABAergic interneurons labeled by green fluorescent protein (GFP) in the lateral amygdala (LA) in vitro from glutamic acid decarboxylase 67 (GAD67)-GFP mice. Neurons were characterized by electrotonic and electrogenic parameters. Cytoplasm was collected from individual neurons, and single-cell RT-PCR

Morphological sex differences and laterality in the prepubertal medial amygdala

Journal of Comparative Neurology, 2007
AbstractThe medial amygdala (MeA) is crucial in the expression of sex‐specific social behaviors. In adult rats the regional volume of the MeA posterodorsal subnucleus (MeApd) is ≈50% larger in males than in females. The MeApd is also sexually dimorphic in prepubertal rats.

Intrinsic circuitry of the central lateral amygdala [PDF]

, 2016
The amygdala is a region of the brain that is responsible for the processing and memory of emotions (e.g. fear). Two main subregions of the amygdala, the basolateral nucleus (BLA) and the central nucleus (CeA), play key roles in the acquisition and expression of fear during Pavlovian fear conditioning, a paradigm that is frequently used to study the ...

The architecture and some of the interconnections of the rat's amygdala and lateral periallocortex

Journal of Comparative Neurology, 1984
AbstractThe connections between the cerebral cortex and amygdala were studied in the rat by means of silver degeneration techniques. To help define the sites of origin and termination of cortico‐amygdaloid connections, the architecture of the cortex and the amygdala was studied in sections from normal brains stained for cells, fibers ...

Molecular and functional properties of neurons in the human lateral amygdala

Molecular and Cellular Neuroscience, 2006
Neuronal properties were investigated through patch-clamp recording in situ in surgical specimens of the human lateral amygdala (LA) obtained from patients with intractable temporal lobe epilepsy. Projection neurons displayed spiny dendrites, action potentials with varying degree of frequency adaptation, and an inwardly rectifying K+ (Kir) conductance ...
