Medulla. The lowest part of the brainstem, the medulla is the most vital part of the entire brain and contains important control centers for the heart and lungs.
What is below the brain?
The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).
Where is the lower brain located?
The brain’s lower-level structures are the oldest in the brain, and are more geared towards basic bodily processes than the higher-level structures. Except for the spinal cord, the brain’s lower-level structures are largely located within the hindbrain, diencephalon (or interbrain), and midbrain.
Which part of the brain is the little brain?
For the longest time the cerebellum, a dense, fist-size formation located at the base of the brain, never got much respect from neuroscientists.
What are the 4 parts of the brain and their functions?
Each hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. 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.

Which side of the brain controls memory?
Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving.
What side of the brain controls vision?
The occipital lobe is the back part of the brain that is involved with vision. Temporal lobe. The sides of the brain, these temporal lobes are involved in short-term memory, speech, musical rhythm, and some degree of smell recognition.
What is the oldest part of the brain?
The Old Brain: Wired for Survival. The brain stem is the oldest and innermost region of the brain. It’s designed to control the most basic functions of life, including breathing, attention, and motor responses (Figure 3.8 “The Brain Stem and the Thalamus”).
Does the brain feel pain?
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
Which is the largest part of the brain?
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. Cerebellum: is located under the cerebrum.
Does the cerebellum control emotions?
The cerebellum is particularly well suited to regulate emotion, as connections with limbic regions, including the amygdala, the hippocampus, and the septal nuclei have been posited [9].
Is cerebellum part of the brain?
The cerebellum (“little brain”) is a structure that is located at the back of the brain, underlying the occipital and temporal lobes of the cerebral cortex (Figure 5.1). Although the cerebellum accounts for approximately 10% of the brain’s volume, it contains over 50% of the total number of neurons in the brain.
What are the 4 major areas of the brain?
Rotate this 3D model to see the four major regions of the brain: the cerebrum, diencephalon, cerebellum, and brainstem. The brain directs our body’s internal functions. It also integrates sensory impulses and information to form perceptions, thoughts, and memories.
What are the 7 parts of the brain?
Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain.
Which organs in the cell works like brain?
It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate’s body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion.
