Final answer:
The neural-network model for executive attention in the motor cortex involves components of the brain's frontal lobe, specifically the prefrontal area, responsible for higher cognitive processes that enable goal-directed behavior and concentration.
Step-by-step explanation:
The question addresses the neural-network model used for executive attention in the motor cortex. The central nervous system is comprised of two main organs: the brain and the spinal cord. The part of the brain that controls conscious functions, including reasoning, is the frontal lobe, particularly the prefrontal area, which is essential for executive functions. These functions enable goal-directed behaviors and involve cognitive processes like working memory.
Executive attention is largely governed by the prefrontal regions of the frontal lobe which is responsible for inhibiting distractions, allowing a person to concentrate on objectives and steer behavior towards achieving these goals. The motor cortex, located in the frontal lobe, is primarily tasked with controlling voluntary motor functions.
Understanding the interaction between these brain regions, particularly how attention is focused and maintained during motor tasks, is a critical aspect of neural network modeling. This can be seen in the way executive attention governs the prioritization of sensory input and the coordination of motor outputs for goal-directed actions which are fundamental in designing systems to support attention.
