The brain is an organ which consists of a mass of nerve tissue which is surrounded by the skull. Its major divisions are cerebrum, cerebellum and brain stem. The cerebrum is divided into two hemispheres, which are further divided into lobes. It is responsible for problem solving, coordinating motor skills, attention, interpreting sensory information, interpreting emotions, etc. The cerebellum helps in the management of fine motor skills as well as helping the body maintain its balance and posture. The functions of the brain can be broadly categorized into sensory information processing, maintaining breathing and blood pressure, and regulating the release of hormones. The book aims to shed light on some of the unexplored aspects of brain functions and the recent researches in this field. Its extensive content provides the readers with a thorough understanding of the subject. This book will prove to be immensely beneficial to students and researchers in this field.
