Clinical observations and findings on imaging are reported in six newborns with symmetrical thalamic lesions (STL). In three cases the diagnosis was confirmed by postmortem examination. Characteristic observations in this series and 17 previously reported cases include no evidence of perinatal asphyxia, high incidence of polyhydramnios, absent suck and swallow, absent primitive reflexes, apprec...

متن کاملThalamic extrapontine lesions in central pontine myelinolysis.
Central pontine myelinolysis (CPM) is a well-known entity first described by Adams et al. in 1959 [1). This demyelinating disorder is associated with electrolyte disturbances (particularly of sodium) and typically occurs in the setting of alcoholism and malnutrition . Extrapontine myelinolysis (EPM) is identified pathologically in about 53% of cases [2] and, of these, thalamic lesions are detec...
متن کاملVisual recognition impairment following medial thalamic lesions in monkeys.
Monkeys with surgical lesions which removed the medial portions of the medial and anterior thalamic nuclei were markedly impaired on a test of object recognition. The same animals were able to learn visual pattern discriminations and a spatial delayed response task at a normal rate. These findings indicate that lesions in the medial thalamus produce a selective impairment in visual recognition ...
متن کاملMediodorsal thalamic lesions impair trace eyeblink conditioning in the rabbit.
Rabbits received lesions of the mediodorsal nucleus of the thalamus (MDN) or sham lesions and were subjected to classical eyeblink (EB) and heart rate (HR) conditioning. All animals received trace conditioning, with a.5-sec tone conditioned stimulus, a .5-sec trace period, and a 50-msec periorbital shock unconditioned stimulus. Animals with MDN lesions acquired the EB conditioned response (CR) ...
