MEDICAL PHYSIOLOGY

Detailed explanation-1: -Galen was the leading physician of the Roman empire during the last half of the second century. Unlike some of his predecessors, Galen concluded that the brain controlled cognition and willed action.

Detailed explanation-2: -The cerebellum is the brain’s locomotion control center. Every time you shoot a basketball, tie your shoe, or chop an onion, your cerebellum fires into action. Found at the base of your brain, the cerebellum is a single layer of tissue with deep folds like an accordion.

Detailed explanation-3: -In 335 BC, Greek philosopher Aristotle thought the brain was simply a radiator that kept the all-important heart from overheating. Around 170 BC, Roman physician Galen suggested the brain’s four ventricles (fluid-filled cavities) were the seat of complex thought, and determined personality and bodily functions.

Detailed explanation-4: -The birth of neuroscience began with Hippocrates some 2500 years ago. While his contemporaries, including Aristotle, believed that the mind resided in the heart, Hippocrates argued that the brain is the seat of thought, sensation, emotion and cognition.
