Involved in the regulation of sleep and wakefulness.
The area-6 of the brain, also known as the premotor cortex or supplementary motor area, has several functions:
1. Weak inhibition of stretch reflex and grasp reflex: This means that it helps suppress muscle tone and control reflexive movements.
2. Initiates gross movements that involve groups of muscles to support and facilitate fine movement: It plays a role in coordinating larger movements that involve multiple muscle groups to support and enhance fine motor skills.
3. Executes skilled movement and gestures: This area is responsible for executing complex and precise movements, such as those involved in playing a musical instrument or performing fine motor tasks.
4. Center for head rotation: It directs the head to objects, allowing for focused visual attention and tracking.
5. Controls complex movement of facial expression, jaws, tongue, larynx, pharynx, and respiratory muscles: The lower part of area-6 specifically controls the complex movements involved in speech, facial expressions, chewing, swallowing, and breathing.
6. Initiates automatic (involuntary) movements performed subconsciously: It is involved in generating automatic movements, such as the swinging movement of the arms during walking, without conscious effort.
7. Center for verbalization: Area-6 is also involved in the control of verbalization, which is the process of expressing thoughts and ideas through speech.
8. Involved in the control of the Autonomic Nervous System (ANS): The premotor cortex has connections to areas involved in regulating the autonomic nervous system, which controls various involuntary bodily functions such as heart rate, breathing, and digestion. However, the specific mechanisms of this control are still being researched.
Overall, area-6 plays a crucial role in motor control, coordination, and the initiation of voluntary and involuntary movements.
Area-6 of the brain, also known as the premotor cortex or supplementary motor area, serves multiple functions related to movement and control. Here is an explanation of each function:
1. Weak inhibition of stretch reflex and grasp reflex: The premotor cortex helps suppress muscle tone, which prevents excessive contraction of muscles. It also plays a role in inhibiting primitive reflexes like the stretch reflex and grasp reflex.
To understand this function in more detail, it is important to study neurophysiology, which involves learning about the stretch reflex and how the premotor cortex modulates it. Understanding the anatomy and physiology of the brain can be achieved by studying neuroscience or neurobiology.
2. Initiates gross movements that involve groups of muscles to support and facilitate fine movement (Hand skill area): The premotor cortex is responsible for initiating and coordinating complex movements that require the use of different muscle groups. In particular, it plays a crucial role in hand movements and fine motor skills.
To gain a deeper understanding of how the premotor cortex controls hand movements, you can study the anatomy of the brain and the motor pathways involved. You may also explore research articles and textbooks in neuroscience or neurology.
3. Executes skilled movement and gestures: The premotor cortex is involved in planning and executing skilled movements and gestures. This includes activities like playing a musical instrument, typing, or performing precise movements.
To comprehend how the premotor cortex carries out skilled movements, it is essential to learn about the pathways involved in motor planning and execution. This can be achieved by studying neuroscience or motor control literature.
4. Center for head rotation - Directs the head to objects (Head rotation area): The premotor cortex controls head movements, particularly the rotation of the head towards objects of interest.
To understand the mechanisms behind head rotation, one can study the anatomy and physiology of the motor pathways and brain regions involved. Neuroanatomy textbooks and research papers on motor control can provide more in-depth knowledge.
5. Controls complex movement of facial expression, jaws, tongue, larynx, pharynx, and respiratory muscles: The lower part of area-6 in the premotor cortex is responsible for controlling the intricate movements involved in facial expressions, jaw movements, tongue movements, and the control of respiratory muscles.
To delve into the details of how the premotor cortex controls these complex movements, studying the anatomy and physiology of the relevant brain regions and motor pathways is crucial. Resources like neuroscience textbooks and research papers can be helpful.
6. Initiates automatic (involuntary) movements performed subconsciously (swinging movement of arms during walking): The premotor cortex also plays a role in initiating automatic movements that are performed without conscious effort. An example of this is the swinging movement of the arms while walking.
To understand the neural mechanisms behind these involuntary movements, studying motor control and the coordination of movements can be beneficial. Exploring neurophysiology, neuroscience, or motor behavior literature can provide valuable insights.
7. Center for verbalization: Additionally, the premotor cortex is involved in the control of verbalization, specifically in the planning and execution of speech production.
To gain knowledge about how the premotor cortex contributes to speech production, studying the neurophysiology, neural pathways, and brain regions involved in language processing can be helpful. Linguistics, neurolinguistics, and neuroscience research can provide relevant information.
8. Involved in the control of the autonomic nervous system (ANS): The premotor cortex also has involvement in the control of the autonomic nervous system (ANS), which regulates various involuntary bodily functions such as heart rate, digestion, and respiration.
To understand the role of the premotor cortex in autonomic nervous system control, studying the anatomy and physiology of the ANS as well as the interconnections between the premotor cortex and autonomic centers in the brain is necessary. Physiology textbooks and research articles on autonomic function can provide valuable insights.
In general, gaining a comprehensive understanding of the complicated functions of area-6 of the brain requires studying multiple disciplines such as neuroscience, neurobiology, neurophysiology, motor control, and relevant specific fields related to each function detailed above.
