D E L I U S , J. D. A N D K. P E L L A N D E R . Hunger dependence of electrical brain self-stimulation in the pigeon. PHYSIOL. BEHAV. 28(I) 63--66, 1982.---Contrary to recent evidence, further data showing that intracranial self-stimulation behaviour in the pigeon is frequently hunger-dependent is reported. A compilation of reinforcing brain loci in the pigeon suggests an association with two ...
The effect of cholinergic basal forebrain lesions on immunoreactivity to somatostatin (SOM-i) and neuropeptide-Y (NPY-i) was investigated in the rat parietal cortex, 16-18 months after multiple bilateral ibotenic acid injections in the nucleus basalis complex. As a result of the lesion, the cholinergic fiber density in the cortex decreased by 66% with a concurrent increase in SOM-i fibers by mo...
A review of the literature concerning cholinergic manipulations and passive avoidance reveals that state-dependency is usually not controlled adequately, nor is acquisition of the passive avoidance task ascertained before retention is tested. These problems make interpretation of results difficult. We report three experiments on 129 rats, controlling both of these factors, in which scopolamine ...
The role of the nucleus basalis prosencephali (Bas), a frontal forebrain structure peculiar to birds, in the control of forage pecking and apomorphine-induced pecking was investigated. In a quasi-natural grit-grain selection task bilateral coagulations of the Bas and the associated neostratum frontolaterale (Nfl) caused a marked fall in grain per peck uptake and a simultaneous increase in grit ...
A novel neuronal tauopathy, mainly confined to hypothalamus and brainstem tegmentum, has recently been reported in patients with autoantibodies to the neuronal cell-adhesion molecule IgLON5. We describe a patient with anti-IgLON5 syndrome, who presented with dysautonomia and sleep disorder, followed by subacute dementia. Postmortem brain examination disclosed neuronal tau pathology prevailing i...
The nucleus basalis magnocellularis (nbm)-lesioned rat is considered to be a model of the cholinergic dysfunction observed in the cerebral cortices of Alzheimer's disease patients. The cholinergic markers, acetylcholine release and choline acetyltransferase activity, were decreased in the cerebral cortex of the nbm-lesioned rat. Kangenkaryu (KAN), a Chinese traditional medicine, is a typical pr...
Sleep disorders and disruptive nocturnal behaviours are commonly reported in people with senile dementia and present both a significant clinical problem and a cause of increased stress for caregivers. Neuronal degeneration of cholinergic Nucleus basalis Meynert (NBM) neurons promote rest-activity disturbance and Sundowning in Alzheimer's disease. NBM neurons modulate the activity of the mainly ...
