Basal amygdaloid complex afferents to the rat nucleus accumbens are compartmentally organized.
The basal amygdaloid complex (BAC) topographically projects to the nucleus accumbens (Acb) in patchy, inhomogeneous patterns. These termination patterns may be related to the histological features of the Acb that define the shell, core, and adjacent ventral caudate-putamen (CPv), and the ventral striatal compartments providing output to different autonomic, motor, and endocrine targets. Knowled...
متن کاملTegmental afferents of the amygdaloid body in the rat.
Horseradish peroxidase (HRP) was injected to various parts of the amygdala in 50 rats. Retrograde axonal transport revealed that tegmental areas containing biogenic amines: dorsal and median raphe nuclei, locus coeruleus and ventral tegmental area, project diffusely to various amygdaloid areas. Moreover, HRP labeled cells were found in the parabrachial nucleus (following injection of the latera...
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 کاملElectrophysiology of the hippocampal and amygdaloid projections to the nucleus accumbens of the rat: convergence, segregation, and interaction of inputs.
The nucleus accumbens (Nacb) receives inputs from hippocampus and amygdala but it is still unclear how these inputs are functionally organized and may interact. The interplay between these input pathways was examined using electrophysiological tools in the rat, in vivo, under halothane anesthesia. After fornix/fimbria stimulation (Fo/Fi, subicular projection fibers to the Nacb), mono- and polys...
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...
