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...

the parafascicular nucleus (pfn) of thalamus, as a supraspinal structure, has an important role in processing of nociceptive information. in addition, μ-opioid receptor contributes to supraspinal modulation of nociception. in the present study, the effects of microinjection of naloxone (a non-specific opioid-receptor antagonist) and naloxonazine (a specific μ-opioid receptor antagonist) were in...

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...

change in transmitting time of impulses along axons is traditionally attributed to two parameters: the myelin formation and the diameter of neurite, both rising during the postnatal development. in the previous study, we showed that conduction velocity of the fibers projecting from the thalamus to the layer iv of the somatosensory (barrel) cortex increases as a function of age. however, the con...
