Brain vs. Cerebrum

The control center of the central nervous system of an animal located in the skull which is responsible for perception, cognition, attention, memory, emotion, and action.

(informal) An intelligent person.

Example: ‘She was a total brain.’;

(plurale tantum) A person who provides the intelligence required for something.

Example: ‘He is the brains behind the scheme.’;

(in the plural) Intellect.

Example: ‘She has a lot of brains.’;

(in the singular) An intellectual or mental capacity.

Example: ‘Gerald always acts like he doesn't have a brain.’;

By analogy with a human brain, the part of a machine or computer that performs calculations.

Example: ‘The computer's brain is capable of millions of calculations a second.’;

(transitive) To dash out the brains of; to kill by smashing the skull.

To strike (someone) on the head.

To destroy; to put an end to.

To conceive in the mind; to understand.

The whitish mass of soft matter (the center of the nervous system, and the seat of consciousness and volition) which is inclosed in the cartilaginous or bony cranium of vertebrate animals. It is simply the anterior termination of the spinal cord, and is developed from three embryonic vesicles, whose cavities are connected with the central canal of the cord; the cavities of the vesicles become the central cavities, or ventricles, and the walls thicken unequally and become the three segments, the fore-, mid-, and hind-brain.

The anterior or cephalic ganglion in insects and other invertebrates.

The organ or seat of intellect; hence, the understanding; as, use your brains.

The affections; fancy; imagination.

a very intelligent person.

the controlling electronic mechanism for a robot, guided missile, computer, or other device exhibiting some degree of self-regulation.

To dash out the brains of; to kill by beating out the brains.

Example: ‘There thou mayst brain him.’; ‘It was the swift celerity of the death . . . That brained my purpose.’;

To conceive; to understand.

Example: ‘'T is still a dream, or else such stuff as madmenTongue, and brain not.’;

that part of the central nervous system that includes all the higher nervous centers; enclosed within the skull; continuous with the spinal cord

mental ability;

Example: ‘he's got plenty of brains but no common sense’;

that which is responsible for one's thoughts and feelings; the seat of the faculty of reason;

Example: ‘his mind wandered’; ‘I couldn't get his words out of my head’;

someone who has exceptional intellectual ability and originality;

Example: ‘Mozart was a child genius’; ‘he's smart but he's no Einstein’;

the brain of certain animals used as meat

kill by smashing someone's skull

A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision.

(neuroanatomy) The principal and most anterior part of the brain in vertebrates, which is located in the front area of the skull and divided into two hemispheres, left and right, separated by a fissure. In humans it is the largest part of the brain and is responsible for the integration of complex sensory functions and the initiation and coordination of voluntary activity, and the higher mental functions such as consciousness, thought, reason, emotion, and memory.

The anterior, and in man the larger, division of the brain; the seat of the reasoning faculties and the will. See Brain.

anterior portion of the brain consisting of two hemispheres; dominant part of the brain in humans

The cerebrum, telencephalon or endbrain, is the largest part of the brain containing the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.
