association motor area contains what and what area?
The association motor area, also known as the dorsolateral prefrontal cortex, contains:
1. The motor cortex: This area is responsible for planning, coordinating, and executing voluntary movements.
2. The frontal eye field: This area is involved in eye movement control.
It is important to note that the association motor area is part of the broader frontal lobe of the brain, which plays a crucial role in higher cognitive functions such as problem-solving, decision-making, and social behavior.
The association motor area, also known as the premotor cortex, is a region of the brain located in the frontal lobe. It is responsible for planning and coordinating movements, as well as integrating sensory information to guide motor actions. Additionally, it plays a role in fine-tuning movements before they are executed by the primary motor cortex.
The association motor area, also known as the premotor cortex, is a region of the brain that is involved in planning and coordinating voluntary movements. It is located in the frontal lobe of the cerebral cortex, specifically in the area known as the anterior frontal cortex.
To understand what specific areas the premotor cortex contains, we need to refer to a brain map, such as the Brodmann areas mapping system. According to this system, the association motor area primarily contains the following two regions:
1. Brodmann Area 6 (BA6) or the Supplementary Motor Area (SMA): This region is located on the midline of the frontal lobe, just anterior to the primary motor cortex. The SMA is involved in the initiation and coordination of complex movements, especially those involving both sides of the body.
2. Brodmann Area 44 and 45 (BA44 and BA45): These areas are part of the inferior frontal gyrus, specifically the pars opercularis and pars triangularis, respectively. They are associated with the planning and execution of speech production, commonly referred to as Broca's area. BA44 and BA45 also contribute to non-verbal motor functions, such as gestures and facial expressions.
It's important to note that the association motor area is interconnected with other brain regions, including the primary motor cortex, sensory areas, and the basal ganglia, forming a complex network involved in motor control and planning.
