Cortical inputs innervate calbindin-immunoreactive interneurons of the rat basolateral amygdaloid complex.
The present study was undertaken to shed light on the synaptic organization of the rat basolateral amygdala (BLA). The BLA contains multiple types of GABAergic interneurons that are differentially connected with extrinsic afferents and other BLA cells. Previously, it was reported that parvalbumin immunoreactive (PV(+) ) interneurons receive strong excitatory inputs from principal BLA cells but ...
متن کاملCoupled networks of parvalbumin-immunoreactive interneurons in the rat basolateral amygdala.
Recent studies indicate that the basolateral amygdala exhibits fast rhythmic oscillations during emotional arousal, but the neuronal mechanisms underlying this activity are not known. Similar oscillations in the cerebral cortex are generated by a network of parvalbumin (PV)-immunoreactive interneurons interconnected by chemical synapses and dendritic gap junctions. The present immunoelectron mi...
متن کاملSubtypes of substance P receptor immunoreactive interneurons in the rat basolateral amygdala.
Local injections of the neurotoxin SP-saporin into the basolateral amygdala (BLA) are reported to specifically lesion substance P receptor immunoreactive (SPR-IR) interneurons, and to reduce anxiety related behavior. Hence, this technique might provide a means to study how defined interneuron populations regulate neuronal activity in the BLA. However, what interneuron subgroups in the BLA might...
متن کاملRat Amygdaloid Complex
The distribution of GABA-like (GABA-Li) immunoreactivity in the rat amygdaloid complex was studied by using an anti-GABA antibody. GABALi positive neurons and processes were present in every nucleus of the complex. Three patterns of immunoreactivity were revealed: (1) the intercalated masses and the lateral olfactory tract nucleus exhibited the most intense staining of the neuropil, and virtual...
متن کاملAnatomic heterogeneity of the rat amygdaloid complex.
The amygdala is a nuclear complex composed of 13 nuclei and cortical areas and their subdivisions. Tract-tracing studies performed over the past 20 years demonstrate that each nucleus is uniquely connected with other brain areas. Consistent with anatomic heterogeneity, the functions of the amygdala vary from attention to memory to formation of emotional responses to sensory stimuli. Here, we br...
