Organization of the Brain

Organization of the Brain

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Functional Brain Systems: Limbic System

Functional Brain Systems: Limbic System

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Area of Science:

Neuroscience
Oral Health
Human Research

Background:

Limited reviews explore the link between occlusion and brain function.
Occlusion impacts overall bodily health, with a specific focus on neurological effects.
Existing research from 1999-2011 forms the basis of this review.

Purpose of the Study:

To systematically review the effects of occlusion on brain function.
To investigate the relationship between oral/maxillofacial movements and brain activity in sensorimotor cortices.

Main Methods:

Systematic literature review of English articles published between 1999 and 2011.
Articles assessed via online databases and library hard copies.
Categorization of 19 selected articles into five themes: chewing/tongue movements, clenching/grinding, occlusal splints/interference, prosthetic rehabilitation, and pain/stimulation.

Main Results:

Oral and maxillofacial movements, including gum chewing and clenching, activate motor and sensory cortices.
Occlusal interference devices, splints, and implant prostheses influence sensorimotor cortex activity.
Brain activity correlates with the intensity of oral and maxillofacial movements.

Conclusions:

Mastication and other oral movements stimulate cerebral cortex activity.
These movements may play a role in preventing the degradation of brain function.
Further research with larger sample sizes is required to validate these findings.
