Contextual, but not auditory, fear conditioning is disrupted by neurotoxic selective lesion of the basal nucleus of amygdala in rats
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
The basolateral amygdala complex (BLA) is involved in acquisition of contextual and auditory fear conditioning. However, the BLA is not a single structure but comprises a group of nuclei, including the lateral (LA), basal ...
Organization of ventral tegmental area projections to the ventral tegmental area-nigral complex in the rat
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The ventral tegmental area (VTA) is a nodal link in reward circuitry. Based on its striatal output, it has been subdivided in a caudomedial part which targets the ventromedial striatum, and a lateral part which targets the ...
Immunohistochemical localization of nicotinic acetylcholine-receptor subunits in the mesencephalon and diencephalon of the chick (Gallus-gallus)
(Wiley-Blackwell, 1992-03-22)
Monoclonal antibodies against two alpha-bungarotoxin-binding subunits (alpha-7 and alpha-8) of the nicotinic acetylcholine receptors (nAChRs) were used as immunohistochemical probes to map their distribution in the chick ...
The Cholinergic System in Mild Cognitive Impairment and Alzheimer`s Disease: An In Vivo MRI and DTI study
(WILEY-BLACKWELL, 2011)
Few studies have investigated in vivo changes of the cholinergic basal forebrain in Alzheimer`s disease (AD) and amnestic mild cognitive impairment (MCI), an at risk stage of AD. Even less is known about alterations of ...
Commissural NTS lesions and cardiovascular responses in aortic baroreceptor-denervated rats
(1999-10-01)
Both acute (1 day) lesions of the commissural nucleus of the solitary tract (commNTS) and aortic baroreceptor denervation increase pressor responses to bilateral common carotid occlusion (BCO) during a 60-second period in ...
Commissural NTS lesions and cardiovascular responses in aortic baroreceptor-denervated rats
(1999-10-01)
Both acute (1 day) lesions of the commissural nucleus of the solitary tract (commNTS) and aortic baroreceptor denervation increase pressor responses to bilateral common carotid occlusion (BCO) during a 60-second period in ...
Dopamine release in the nucleus accumbens (shell) of two lines of rats selectively bred to prefer or avoid ethanol
(2007)
Lower tissue levels of dopamine and 5-hydroxytryptamine (5-HT) have been found in the nucleus accumbens of alcohol-naïve rats selectively bred to prefer ethanol than in rats bred to avoid it. These findings have led to the ...
The bradycardic and hypotensive responses to serotonin are reduced by activation of GABA A receptors in the nucleus tractus solitarius of awake rats
(Associação Brasileira de Divulgação Científica (ABRADIC), 2005-07-01)
We investigated the effects of bilateral injections of the GABA receptor agonists muscimol (GABA A) and baclofen (GABA B) into the nucleus tractus solitarius (NTS) on the bradycardia and hypotension induced by iv serotonin ...
