In fact, your brain is the boss of your body. It runs the show and controls just about everything you do, even when you're asleep. Not bad for something that looks like a big, wrinkly, gray sponge. Your brain has many different parts that work together.
What are the five main functions of the brain?
The five main functions that the brain serves are:
- Memory and the ability to learn.
- Social interaction.
- Emotion and feelings.
A neuron is a nerve cell in the brain. The human brain is made up of approximately 100 billion (100,000,000,000) neurons. The brain is an organ as it controls the functions of the body. It is sometimes referred to as a muscle of thinking as the brain actually tells your muscles what to do.
That's the answer to why we need a brain. The primary purpose of a brain is to move around our environment in a meaningful way. In fact, one could even argue that most of the brain is dedicated towards actions. People often assume that animals with bigger brains are more intelligent because they have more brain cells.
6 Major Parts of the Brain and What They Do
- Lobes of the Brain. Frontal Lobes.
- Motor Cortex and Somatosensory Cortex. Between the parietal and frontal lobes are two bands across the top of the brain from ear to ear.
- Brain Stem.
- The Limbic System.
The cerebrum. The cerebrum, the large, outer part of the brain, controls reading, thinking, learning, speech, emotions and planned muscle movements like walking. It also controls vision, hearing and other senses.
The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.
Damage to a discrete part of the brain in the left frontal lobe (Broca's area) of the language-dominant hemisphere has been shown to significantly affect the use of spontaneous speech and motor speech control.
The human brain consists of special cells called neurons, which are composed of several parts, including brain fibers known as dendrites. As you learn, these brain fibers grow. In other words, to learn new knowledge, a person must build on information that is already stored in the brain.
The brain's primary building element starts with the brain cells known as neurons. Chemical processes in the brain send out messages through the neurons that determine the mental processes along with thinking. The motor neurons produce the action in our muscles and the sensory neurons connect to our five senses.
Medulla – The primary role of the medulla is regulating our involuntary life sustaining functions such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.
Emotions, like fear and love, are carried out by the limbic system, which is located in the temporal lobe. While the limbic system is made up of multiple parts of the brain, the center of emotional processing is the amygdala, which receives input from other brain functions, like memory and attention.
The parietal lobe is also involved in interpreting pain and touch in the body. Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision. Temporal lobe.
The part of the brain that is responsible for complex thinking is the Frontal Lobe—Located under the forehead, the frontal lobe controls reasoning, planning, voluntary movement, and some aspects of speech. The prefrontal cortex is the part of the frontal lobe right behind the forehead.
2: The brain is the most complex organ in the body. The brain is made up of a complex network of billions of nerve cells called neurons, as well as other kinds of cells, all protected by the bones of the skull. That's a lot of energy for a human organ a little bigger than a softball.
the brain as the center of thought, understanding, etc.; mind; intellect. brains, Slang. a member of a group who is regarded as its intellectual leader or planner: The junior partner is the brains of the firm.
Parietal lobe. The parietal lobe gives you a sense of 'me'. It figures out the messages you receive from the five senses of sight, touch, smell, hearing and taste. This part of the brain tells you what is part of the body and what is part of the outside world.
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.
Deep inside the medial temporal lobe is the region of the brain known as the limbic system, which includes the hippocampus, the amygdala, the cingulate gyrus, the thalamus, the hypothalamus, the epithalamus, the mammillary body and other organs, many of which are of particular relevance to the processing of memory.
The gray matter is made up of about 100 billion neurons that gather and transmit signals while the white matter is made of dendrites and axons that the neurons use to transmit signals. The brain is composted of about 75% water and is the fattiest organ in the body, consisting of a minimum of 60% fat.
After consolidation, long-term memories are stored throughout the brain as groups of neurons that are primed to fire together in the same pattern that created the original experience, and each component of a memory is stored in the brain area that initiated it (e.g. groups of neurons in the visual cortex store a sight,
BRAIN STEM: The part of the brain that connects to the spinal cord. The brain stem controls functions basic to the survival of all animals, such as heart rate, breathing, digesting foods, and sleeping. It is the lowest, most primitive area of the human brain.
