For anyone who wants to increase focus and concentration, do a study in human behavior or a study of the manner in which people respond. This can help to reach a greater understanding of the various parts of the brain. The article that follows does not purport to be a lesson in biology, but it does provide a fairly good explanation of the anatomy of the brain and its functions.
Basically, the brain stimulates the head through cranial nerves, and communicates with the spinal cord that stimulates the body through the spinal nerves. The brain is also the location of all reason and intelligence, aspects that are responsible for cognition, mental focus, perception, concentration, memory and emotions. A developed human brain is composed of three main parts - hindbrain, midbrain, and forebrain, which are further divided into sub parts.
This is the lower part of the brain where it joins the spinal cord. Almost all the nerves that come from the brain or return to the brain pass through the brainstem. The survival and arousal functions are all located in the brainstem, such as those that control breathing, digestion, being awake and alert.
Located at the back, the cerebellum is responsible for balance and muscle coordination: movements involved in eating, walking, talking, and ability to take care of oneself.
- Frontal Lobe
As is evident from the name, it is the front part of the brain. It is one of the most crucial parts and is responsible for a person’s behaviors,
emotions, and cognitive abilities.
The back portion of the frontal lobe is called the prefrontal cortex, and is responsible for higher cognitive functions including an individual’s ability to concentrate, plan, and organize. It also determines the personality. In addition, the back portion contains the nerve cells that control and modify motor functions.
- Parietal Lobe
The central sulcus, a brain fissure extending upward on the lateral surface of the frontal lobe, separates the frontal and parietal lobes. The parietal lobe is divided in two portions, and one of them is located behind the frontal lobe and at the top of the brain. While the right area determines ability to find ways through familiar and new places, the left side is responsible for understanding the spoken and written word.
The primary sensory cortex within the parietal lobes controls sensations of touch and pressure. A large area is connected at the back to the primary sensory cortex. Fine sensations like judgment of texture, weight, size, and shape are the responsibility of this associated area.
- Occipital Lobe
Most of the visual capabilities are handled by the occipital lobe and the areas associated with it. It helps in visual reception and recognition of shapes and color.
- Temporal Lobe
The temporal lobe is divided in two parts: one at either end of the brain, at about ear level. The right lobe focuses on visual memory and the left on verbal memory. Distinguishing one smell or sound from another depends upon the temporal lobe. It is also responsible for storing new information and short term memory.
You can improve your ability to perform certain functions with herbs and vitamins that promote mental focus. However, since your brain performs dual functions, both voluntary and involuntary, it can also help in increasing concentration or mental focus. A healthy body houses a healthy mind, and your brain health determines how your mind will ultimately respond to stimulations.
