what are the three functions of the brain?

The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

The nervous system has three main functions: To collect sensory input from the body and external environment. To process and interpret the sensory input. To respond appropriately to the sensory input.

The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The central nervous system (CNS) is composed of the brain and spinal cord.

The nervous system can be functionally divided into 3 actions: sensation, integration, and response. The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses).

It assembles the messages in a way that has meaning for us, and can store that information in our memory. The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The central nervous system (CNS) is composed of the brain and spinal cord.

What is the relationship between the brain and the mind? The brain is the central processing unit of the body and plays a key role in translating the content of the mind (your thoughts, feelings, attitudes, beliefs, memories and imagination) into complex patterns of nerve cell firing and chemical release.

Temporal Lobe. The temporal lobes contain a large number of substructures, whose functions include perception, face recognition, object recognition, memory, language, and emotion.

The cortex can be divided into three functionally distinct areas: sensory, motor, and associative. The main sensory areas of the brain include the primary auditory cortex, primary somatosensory cortex, and primary visual cortex. In general, the two hemispheres receive information from the opposite side of the body.

The Prefrontal Cortex area controls the "executive functions" of the brain including judgment, impulse control, management of aggression, emotional regulation, self regulation, planning, reasoning and social skills.

The brain stem connects the brain with the spinal cord. It controls hunger and thirst and some of the most basic body functions, such as body temperature, blood pressure, and breathing. The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges.

Each lobe controls specific functions. For example, the frontal lobe controls personality, decision-making and reasoning, while the temporal lobe controls, memory, speech, and sense of smell.
906417
The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior.

The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.

Divisions of the Nervous System The nervous system has three broad functions: sensory input, information processing, and motor output.
