Hello everyone, and welcome to my second blog post.
Today we will be breaking down parts of the brain as well as their function.
About the Brain:
The cerebrum, brain stem, and cerebellum are only a few of the elements that make up the brain. Six brain areas make up the cerebrum, which spans two hemispheres. As depicted in the picture above, the frontal, parietal, occipital, and temporal lobes may all be seen from the outside of the brain. The limbic and insular lobes, which are located within the cerebrum, are the other two lobes. The cerebral cortex is the brain's outermost layer, comprised mostly of grey matter. It is the most visible structure of the human brain, and despite being only a few millimeters thick, it accounts for around half of the brain's weight.
Neurons are the brain's primary communicators; they transmit messages from one region to another, ultimately initiating actions, encoding and retrieving memories, and producing the sensation of being alive. The cortex, as well as other parts of the limbic and insular lobes, contains a dense collection of neurons. The messages are sent by neurons, and they are supported and facilitated by glial cells, which are a type of cell.
Location and function of the main parts of the brain:
1) Frontal Lobes: The frontal lobes are right behind the forehead. The frontal lobes have a role in voluntary movement, expressive language, and other functions such as higher-level executive activities like planning, self-monitoring, organizing, and controlling one's behaviors in order to accomplish a goal. The frontal lobes control our behavior and emotions. They define our personality.
2) Temporal Lobes: The temporal lobes are behind the ears and are the second-largest lobes. They are most typically linked to the processing of auditory information and memory encoding. The temporal lobes are also thought to be involved in the processing of language, emotions, and some aspects of visual perception.
3) Parietal Lobes: Near the rear and top of the skull are the parietal lobes. They are necessary for the processing and interpretation of somatosensory information. For example, they use touch to inform us about items in our external surroundings as well as the location and movement of our bodily parts. The parietal lobes also handle sensory integration and the creation of a spatial coordinate system to represent the world around us.
4) Occipital Lobes: The occipital lobes are located near the back of the skull and are important for color, form, and motion perception.
5) Cerebellum: The cerebellum (Latin for "little brain") is a small brain structure positioned immediately above the brain stem and tucked beneath the cerebral cortex in the back of the brain. It is involved in voluntary motor movement coordination, balance and equilibrium, and muscular tone. In comparison to the frontal and temporal lobes, as well as the brain stem, it is comparatively trauma-resistant.
