What Is the Largest Part of the Brain?

The cerebrum, which is the front section of the brain, is where the majority of the processing takes place.

The cerebral cortex – or ‘gray matter’ – makes up 85% of the brain’s volume and contains two types of cells: neurons and neuroglial cells. Neurons are specialized for information gathering and communication while neuroglial cells help to control chemical composition within different sections of the central nervous system.

Its functions range from sensing sensations to understanding and thinking. It aids in emotional responses, long-term memory, learning languages and how we sleep.

Speech and judgment are two of the most common functions attributed to the cerebrum. The cerebrum helps regulate the cognitive abilities which include speech, judgment, reasoning, and perception. It also regulates heart rate, blood pressure, body temperature.

The brain is made up of three main lobes: the frontal lobe, temporal lobe, and occipital lobe. The frontal lobe controls voluntary muscle movements on both sides of your body, expression on one side of your face, rational thinking (morality), attention span, personality traits (such as shyness or promiscuity). It has an intricate relationship with other parts of the brain that regulate emotion- more specifically it regulates happy emotions (such as laughter) and unhappy emotions (such as fear).
