Bilateral transient changes in thalamic n. ventroposterior lateralis after thoracic hemisection in the rat
نویسندگان
چکیده
We made simultaneous bilateral recordings of unit activity in the n. 9 ventroposterior lateralis (VPL) in intact rats, and after acute and chronic left thoracic 10 hemisection. We observed an immediate bilateral decline in multireceptive units, 11 reflecting a loss of nociceptive input on the lesion side and a loss of low threshold 12 inputs contralaterally. Unit properties were restored to normal by 6 weeks. Mean 13 spontaneous discharge frequency remained unchanged in left VPL at all intervals.

متن کاملTransformation of diffuse beta-amyloid precursor protein and beta-amyloid deposits to plaques in the thalamus after transient occlusion of the middle cerebral artery in rats.
BACKGROUND AND PURPOSE The present study examined the long-term presence of beta-amyloid precursor protein (APP) and beta-amyloid (Abeta) accumulation in the rat thalamus after focal cerebral ischemia. METHODS Male Wistar rats were subjected to transient middle cerebral artery occlusion (MCAO) for 2 hours. Sensorimotor outcome was assessed using a tapered/ledged beam-walking task after operat...
متن کاملEffect of Coenzyme Q10 (ubiquinone) on hippocampal CA1 pyramidal cells following transient global ischemia/reperfusion in male wistar rat
Ischemia/Reperfusion (I/R)-induced cerebral injury has been reported as a leading cause of deathand long-term disabilities. Hippocampus is an area which is more sensitive to be affected by I/Rand hypoxic conditions. Coenzyme Q10 is a strong antioxidant which plays a role in membranestabilization. This study aims to investigate the possible role of CoQ10 in ameliorating thehistomorphological cha...
متن کاملAsterixis as a Focal Neurologic Sign: Report of Three Cases and Literature Review
Asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. Although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but Lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. In this article, three cases of acu...
متن کاملNeuroprotective Effect of Paroxetine on Memory Deficit Induced by Cerebral Ischemia after Transient Bilateral Occlusion of Common Carotid Arteries in Rat
Aims:Memory deficit is the most visible symptom of cerebral ischemia. The hippocampus is sensitive against cerebral ischemia. Oxidative stress and inflammation are involved in the pathological process after cerebral ischemic injury. Paroxetine has anti-oxidative and anti-inflammatory effects. In this study the effect of paroxetine on memory deficit after cerebral ischemia was investigated. Meth...
