Brain Function and Structure
- The cerebrum is the largest part of the brain, divided into left and right hemispheres
- Hemispheres control higher brain functions such as thought, memory, and voluntary movement
- Cerebral hemispheres are connected by the corpus callosum, with each controlling opposite sides of the body and having specialized functions
- The cerebral cortex, the outer layer of the cerebrum, is composed of grey matter. It is involved in perception, reasoning, language, and voluntary movements
- The frontal lobe is located at the front of the brain. It's responsible for planning, decision-making, problem-solving, and voluntary movement. It also contains the motor cortex.
- The parietal lobe is located behind the frontal lobe. It processes sensory information, such as touch, temperature, and spatial awareness.
- The temporal lobes are located on the sides of the brain. They are involved in hearing, memory, and language comprehension
- The occipital lobe is located at the back of the brain. It processes visual information.
