May 12, 2024 · Have you ever wondered how your brain creates thoughts or why something randomly popped into your head? It may seem like magic – but actually the brain is like a supercomputer inside your head that helps you think, learn and make decisions.
Feb 20, 2024 · The three main parts of the brain are the cerebrum, cerebellum, and brainstem, but these portions contain many key sections. The human brain is the epicenter of our nervous system and plays a pivotal role in virtually every aspect of our lives.
Oct 20, 2023 · The left brain is associated with logic, analytical thinking, and language processing, while the right brain is linked with creativity, intuition, and holistic thinking. However, this is an oversimplification, as both hemispheres cooperate in most activities.

The cerebrum is divided into two halves: the right and left hemispheres(Fig. 2). The left hemisphere controls the right half of the body, and the right hemisphere controls the left half. The two hemispheres are connected by a thick band of neural fibers known as the corpus callosum, consisting of about 200 million axons. The corpus callosum allows ...
Each cerebral hemisphere can be subdivided into four lobes, each associated with different functions. Figure 3.The cerebrum is divided into four lobes: frontal, parietal, occipital, and temporal.
The surface of the cerebrum is called the cerebral cortex and has a wrinkled appearance, consisting of bulges, also known as gyri, and deep furrows, known as sulci(Figure 8). A gyrus (plural: gyri) is the name given to the bumps and ridges on the cerebral cortex (the outermost layer of the brain). A sulcus (plural: sulci) is another name for a groo...
Within the brain, there are fluid-filled interconnected cavities called ventricles, which are extensions of the spinal cord. These are filled with a substance called cerebrospinal fluid, which is a clear and colorless liquid. The ventricles produce cerebrospinal fluid and transport and remove this fluid. The ventricles do not have a unique function...
Neurons are the nerve cellsof the central nervous system that transmit information through electrochemical signals throughout the body. Neurons contain a soma, a cell body from which the axon extends. Axons are nerve fibers that are the longest part of the neuron, which conduct electrical impulses away from the soma. There are dendrites at the end ...

Jan 17, 2024 · Forebrain. Midbrain. Hindbrain. While there are a few different ways to divide the brain, the developmental division roughly organizes the brain into three general regions: forebrain (also known as the prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon).
Main Parts of the Brain and Their Functions. At a high level, the brain can be divided into the cerebrum, brainstem and cerebellum. Cerebrum. The cerebrum (front of brain) comprises gray matter (the cerebral cortex) and white matter at its center. The largest part of the brain, the cerebrum initiates and coordinates movement and regulates ...
