| Research Abstract |
Aims of this research is a co-operative and an interdisciplinary study of psychological and physiological mechanisms of biological information processing and its dysfunction. The electrophysiological and/or biochemical signs of brain activities both in normal or handicapped humans and in animals are examined and are related to the behavioural signs of various types of disorders. These studies are divided three themes ; i. e., (1) perception and cognition, (2) learning and memory, (3) consciousness and biorhythms, and three groups of investigators shared one of these research. The main results are summarized as follows :
1. The first group investigated human perceptual and cognitive processing, mainly a visual information processing. Evoked potentials exposed by light or figures were recorded during the various types of mental tasks in normal adults and mental retarded. It was showed that the perceptual process were closely related to perceptual process both in normals and handicapped an

d supposed the mathematical models of brain mechanism in nomal perceptional processing and their significance of dysfunctional processing in handicapped.
2. The second group investigated the brain mechanism of learning and memory processes in animal subjects and related to various types of human disorders. The main themes were as follows ; speech processing birds and speech disorders, effects of psychotropic drug and learning disorders and kindled neronal activities in rats and epilepsy. These research results showed the specific characteristics of normal and/or abnormal learning process and neurophysiological and biochemical mechanisms in handicapped were supposed.
3. The third group investigated the variability of consciousness both in human and animal subjects. The electrophysiological signs of sleep-awakening rhythm or attentional states in the various type of handicapped ; e. g., mental retarded, visual handicap, attention deficits, etc., and activity rhythm in rats were examined. These research results indicated that many handicapped showed specific abnormal signs of biorhythms and/or variation of attentional states and significance of external factors in fetal period were disussed.
4. A synthetic discussion were conducted in the last research term and supposed that the physiopsychological techniques are very useful in the study of human information processing and that the characteristics and causes of dysfunction in handicapped may be specified by the brain mechanisms. Less
