AP PSYCHOLOGY

Detailed explanation-1: -A small amount of brain tissue from a person cannot be distinguished from a small amount of brain tissue from a monkey. The human brain produces its own natural opiates that elevate mood and ease pain. The brain accounts for a larger percentage of body weight in humans than in any other species.

Detailed explanation-2: -The information systems of humans and other animals operate so similarly that you could not distinguish between small samples of brain tissue from a human and a monkey. This allows researchers to study other animals to discover how our own systems work.

Detailed explanation-3: -Answer and Explanation: The region of the human brain that best distinguishes us from other animals is the cerebral cortex. It is present in the outermost part of the brain. It includes the parietal, occipital, frontal, and temporal lobes.

Detailed explanation-4: -The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.

Detailed explanation-5: -Similarities Between Human and Animal Brain The brain of both are made up of neurons and neuroglia. Its main function is to control thoughts and body movement. The brain of all the vertebrate animals is divided into forebrain, midbrain, cerebellum, hind brain, medulla oblongata and pons.
