こころと脳の基礎知識
精神医学では、こころの働きを脳の機能と切り離して理解することはできません。感情や思考、記憶、睡眠や覚醒といった精神活動は、脳の働きと密接に関わっています。近年の脳科学や睡眠研究の進歩によって、こころと脳の関係についての理解は着実に深まってきました。
精神現象の背景にある脳の働きや、睡眠・覚醒の仕組み、発達や記憶など、こころと脳の関係を理解するための基礎的な知見を扱っています。
Mind and Health
Contributing author: Yuhei Kayukawa
The mental health of university students in Japan is a growing concern, with increasing incidence of conditions such as depression, panic disorder, eating disorders, and sleep disorders.
Based on insights from psychosomatic medicine and neuroscience, this article highlights the importance of psychiatric care, counseling, cognitive behavioral therapy, and sleep improvement in mental health management.
Early intervention within university settings plays a crucial role in academic continuity and occupational adjustment, and maintaining mental health during young adulthood is closely linked to overall stability in later social life.

Brain and Mind
Contributing author: Yuhei Kayukawa
This article reviews recent advances in psychiatry and neuroscience. Mental functions such as cognition, consciousness, memory, and emotion are closely linked to specific brain regions. Stress and trauma can affect structures such as the hippocampus and prefrontal cortex.
Sleep–wake rhythms and seasonal variations also play important roles in mental functioning. Psychiatric disorders arise from complex interactions between genetic and environmental factors, influencing the development of conditions such as schizophrenia and mood disorders.
Modern psychiatry increasingly adopts a mind–body integrated perspective, using neuroimaging techniques such as EEG, PET, and SPECT to observe brain activity. These approaches deepen the understanding of both treatment and prevention from a unified biological framework of mind and body.

Sleep is for the brain, by the brain, and of the brain.
Contributing author: Yuhei Kayukawa
Human emotions and daily physical condition are often difficult to observe directly, but they are grounded in a tangible biological organ: the brain. In particular, sleep is an essential physiological process that supports brain function and maintains mental health.
As expressed in the phrase, “Sleep is for the brain, by the brain, and of the brain,” sleep is not merely a state of rest. It is deeply involved in higher brain functions such as memory consolidation and emotional regulation. Furthermore, sleep disturbances such as insomnia and hypersomnia are closely associated with mental health conditions including anxiety and depression.
This page introduces the basic mechanisms of the mind and brain, as well as their relationship with sleep, in an accessible manner. It aims to help readers notice subtle changes in their daily lives and better understand the importance of sleep for mental well-being.
