P8: Thalamic Damage and Memory
Memory is the cognitive ability that allows acquiring, store and recalling information. Anterior thalamic dysfunction creates memory deficits in rats and humans. Anterior thalamus forms a memory network in connection with the hippocampus. This connectivity profile proposes that ventrolateral and anterior thalamus may display a nexus between reminder and control functions, such as action or atte...
متن کاملDiffuse thalamic projection system in monkey.
IN 1942, Dempsey and Morison (4-6, 24) discovered in cats a thalamic system which upon direct repetitive stimulation evoked recruiting wave responses in broad areas of the cortex. Evidence was presented that the physiological counterpart of this response to stimulation was burst or spindle activity recorded from the cortex of cats under surgical barbiturate anesthesia. Interest in the mechanism...
متن کاملThalamic projection to frontal cortex in man.
The object of this communication is to report the present position at the Maudsley laboratory of research on the projection of nerve cells of the human thalamus on to frontal cortex. Previous, more tentative, reports on this topic were published by Meyer, Beck, and McLardy in 1947 and by Meyer, McLardy, and Beck in 1948. The main material used consisted of 54 cerebral hemispheres with varied le...
متن کاملAtaxic hemiparesis following thalamic infarction.
We describe a 73-year-old man with ataxic hemiparesis following infarction of the ventrolateral nucleus of the thalamus demonstrated by computed tomography and magnetic resonance imaging. Cerebellar ataxia was most likely due to interruption of the dentatorubrothalamocortical fibers at the level of the injured ventrolateral nucleus. Hemiparesis was probably caused by local edema compressing the...
متن کاملOrganization of the diffuse thalamic projection system.
increment. Attention was drawn to the close resemblance of these recruiting I , responses to spindle bursts, occurring spontaneously in barbiturate anesthesia, and evidence was presented that the two utilized common neural ' pathways. Since then, other proposals concerning the functional significance of this diffuse thalamic projection system have been made, the most dramatic being Jasper's hyp...
