| Abstract | The neocortex of the human brain is highly developed compared with those of the other mammals. For instance, the logarithm of human brain weight is non-linear to the logarithm of body weight. Human ha...s specialized brain areas that process the face and language. To unlock the complex functions of the human brain, it is necessary to explore the human brain non-invasively. So far, high-density electroencephalo-graphy (EEG), magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) are available in the field of Clinical Neurophysiology. More than 25% of information from the real world is processed by the visual system. Human visual system consists of multiple, parallel channels which process different information, and each channel constitutes a set of sequential processes. There are two major visual streams; The magnocellular (M) and parvocellular (P) pathways. The M pathway is fast conducting and specialized for processing transient information. Thus, the M pathway is most sensitive to stimuli with low spatial and high temporal frequencies and provides information on motion and stereopsis. The P pathway is more sensitive to higher spatial and lower temporal frequencies and processes color information and face perception. Once the functions of the parallel visual pathways are disrupted or modulated by the disease pathology, higher cognitive functions are significantly altered. My interest is to solve the mystery of the human brain with scientific approach. Thus, I have been studying the mechanisms of the neuropsychiatric diseases. Accordingly, the possible pathophysiological mechanisms of chromatic sensitive epilepsy, mild cognitive impairment and autism spectrum disorder have been established in terms of the altered parallel visual processing.show more |
