Brain Function In Our Daily Life

The brain is an amazingly complex organ. It controls virtually every part of our bodies and gives us thought and emotion. There has been a great deal of work over the years in regard to brain function.

So let’s discuss some of the key parts of the brain and describe their critical function.

- Cerebral Cortex: This is the hemispheric outer sections of the brain. There is a left hemisphere and a right hemisphere. Both of them can analyze sensory data, learn new information, make decisions, formulate thoughts and perform memory functions.

- Corpus Callosum: This connects the left hemisphere to the right hemisphere which allows for communication between the two.

- Frontal lobe: This part of the brain has to do with cognition and memory. The prefrontal section provides us with the ability to concentrate and elaborate on thought. It is also known as the gatekeeper since it helps to provide us with judgment and inhibition. Many of our personality and emotional traits reside in the frontal lobe. This section also provides voluntary motor activity through the motor cortex. And it helps us to communicate a spoken language through the motor controls of our mouth.

- Parietal lobe: This is the area which processes much of the visual stimuli. It is how we see and respond to what we see.

- Occipital Lobe: This also has to do with visual sensory information and how it is processed.

- Temporal Lobe: The area of the brain which processes auditory sensory input. It is also related to language (how we hear and respond to auditory stimuli). And it has memory functions as well.

- Limbic System: This section of the brain processes olfactory sensations. It provides us with the sense of smell. This section also has to do with sex, rage, fear and other emotions.

- Basal Ganglia: This helps to cause conscious movement. It provides balance and postural movement.

It is interesting to note that in some cases, damage to certain sections of the brain can cause some functions in those areas to be lost either permanently or at least temporarily. However there are many cases where other undamaged sections of the brain can be taught to take over certain functions which had been lost due to the injury or damage.

Therefore someone who had some damage to a portion of the motor function of the brain can apply techniques and exercises to teach other sections of the brain to take over some motor functions and provide them with the ability to walk, talk, etc.
