Popular culture, from movies, advertising, to self-help books, is captivated by left-brain/rightbrain differences and how these might influence our personalities, moods, and capabilities. Considering the interest in understanding the scientific basis for lateralized neural functions, it is surprising that model systems have not played a more dominant role in research on brain asymmetry. The lon...

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...

This paper describes an experiment in which we tried to predict the learner’s answers from his brainwaves. We discuss the efficiency to enrich the learner model with some electrical brain metrics to obtain some important information about the learner during a test. We conducted an experiment to reach three objectives: the first one is to record the learner brainwaves and his answers to the test...

Background Prosopometamorphopsia is a disorder of face perception in which faces appear distorted to the perceiver. Cases with unilateral prosopometamorphopsia caused by splenial lesion have been very rarely reported. Case Report A 52-year-old right-handed woman complained that the left half of people’s faces looked distorted. She stated that objects other than the face looked normal. Brain mag...

What determines the laterality of activation in motor cortex for words whose meaning is related to bodily actions? It has been suggested that the neuronal representation of the meaning of action-words is shaped by individual experience. However, core language functions are left-lateralized in the majority of both right- and left-handers. It is still an open question to what degree connections b...

OBJECTIVE Neuro-electrophysiological tools have been widely used in heroin addiction studies. Previous studies indicated that chronic heroin abuse would result in abnormal functional organization of the brain, while few heroin addiction studies have applied the effective connectivity tool to analyze the brain functional system (BFS) alterations induced by heroin abuse. The present study aims to...
