The brain works in various ways as the center of the body for thoughts and actions. It does not act like a single mass, instead, the brain has different functions for each part. In brain science, this is called “functional localization of the brain”.
\nThe functional localization of the brain was first discovered around 70 years ago by a Canadian brain surgeon, Wilder Penfield, who applied electrical stimulation to the surface of the brain when performing surgery on patient’s brain. When you give an electrical stimulus to a certain part, the feet will move; when you stimulate another part, the hands move; and when you stimulate another part, the individual can feel as if his or her hands are touched.
\nDr. Penfield created a map of the functional localization of the brain by recording the parts of the senses and movements, such as which part of the brain was stimulated and which part responded.
\nIt seems that this operation can be done only because the organ does not feel pain when the brain is given electrical stimulation. In general, headaches does not mean that the brain is feeling pain; rather, the nerves in the skin of the head and the blood vessels are “feeling pain”.
\nNowadays, the method of Dr. Penfield is no longer an acceptable method. Currently, methods such as painless optical topography and MRI are used instead.<\/p>\n","protected":false},"excerpt":{"rendered":"
