Distribution of protein kinase C in the CNS of rat is presented based on immunohistochemical analysis with monoclonal antibodies against this protein kinase. Protein kinase C-like immunoreactivity was discretely localized and associated with neurons. Most, if not all, glial cells were not significantly stained. The greatest density of the immunoreactive material was seen in the following region...
Phosphorylation of neural proteins in response to a diverse array of external stimuli is one of the main mechanisms underlying dynamic changes in neural circuitry. The NR2B subunit of the NMDA receptor is tyrosine-phosphorylated in the brain, with Tyr-1472 its major phosphorylation site. Here, we generate mice with a knockin mutation of the Tyr-1472 site to phenylalanine (Y1472F) and show that ...
Many researchers have reported that the magnitude of decrease in cortical choline acetyltransferase (ChAT) following excitotoxic lesions of the nucleus basalis magnocellularis (nbm) is unrelated to the degree of cognitive impairment. Recently, an explanation has been offered for this lack of correlation: different excitotoxins, when injected into the nbm, differentially affected cholinergic pro...
PURPOSE: According literature data the animal's response to stress depends not only upon the state and conditions of the animal but also upon the nature of the stressor itself. It is known that stress have wideranging effects on neuroendocrine, autonomic, immune, and hormonal function. Different research groups have shown induction of acute physical stress by low temperature exposure which have...
Previous studies have reported hyperphagia and obesity in female rats with bilateral lesions of the most posterodorsal part of the amygdala. In rats with unilateral posterodorsal amygdaloid lesions, a dense pattern of anterograde degeneration appears in the ipsilateral ventromedial hypothalamus, but not the contralateral nucleus. In the present study, female rats with unilateral ventromedial hy...
Experiments were performed on brains of 15 cats with the use of horseradish peroxidase (HRP) retrograde transport method. After injections of HRP to the insular cortex, relatively great numbers of labeled neurons were found in all main nuclei of the amygdaloid body. After injections to the anterior part of the granular insular cortex numerous labeled neurons were located in the lateral, central...
Although the amygdala complex has long been known to exert a profound influence on cardiovascular activity, the neuronal and connectional substrate mediating these influences remains unclear. This paper describes a direct amygdaloid projection to medullary sensory and motor structures involved in cardiovascular regulation, the nucleus of the solitary tract (NTS) and the dorsal motor nucleus (DV...
Kainic acid (KA) was injected systemically, intracerebroventricularly (i.c.v.) and focally in the amygdala and other deep brain structures in the rat. EEG and behavioral changes were studied in relation to the neuropathology which developed subsequently. Following intra-amygdaloid KA injection, diazepam blocked the epileptic events induced by the toxin, and abolished the neuronal loss usually s...
