The frontal lobe is the part of the brain that most manages ‘human functions.’ It’s most complex and recently evolved part of the brain.
It functions across the control of motor skills, higher level cognition, and expressive language. The part of the brain located at the front of the head or forehead. Let’s look at the structure and function of each of the brain lobes. It handles the many signals responsible for perception, movement, and mental processes. The cerebral cortex as a brain part in humans is a recent development in the course of evolution. Now we will take a trip through the different human brain parts, exploring their function.īrain structure of the cerebral cortex is divided into four lobes with different functions. While the inner and lower parts of the brain control simpler and more basic functions like breathing and blood pressure. The outer parts control the more emotional and thought based functions. These are located from inside of the brain to the brain surface. These neurons are connected by trillions of connections or synapses.Īs a general rule, the function of brain parts arrange from simple to complex.The human brain has billions of nerve fibers (axons and dendrites) - the “white matter.”.The human brain contains close to 86 billion nerve cells (neurons) - the “grey matter.”.At 2% of our body weight, humans have the largest brain of all vertebrates relative to body size.Today research is beginning to unearth the vast complexity of the human brain.Ī glance at the function of the human brain parts In higher consciousness mammals, it projects emotions, feelings, communications, creativity, and memories. Higher brain function includes feeding, hunger, digestion, hormones, and sleep cycles. These include breathing, heart rate, muscle movement, and the senses. From the time of birth, the newborn brain begins to direct deep survival functions. The parts of the human brain are unique from anything else. For example, mice, chickens, and apes all have different brain structure due to the function require. Across different species, brain parts are used for certain functions and basic behaviors.
Scientists don’t truly understand the exact way that brains evolve.
The first brain appeared in the fossil record 550 million years ago. It’s the defining feature of the human species. The human brain is the most remarkable organ on planet earth.
