Final answer:
The frontal cortex is divided into four general categories: the primary motor cortex, premotor cortex, Broca's area, and the frontal eye fields, with the prefrontal cortex being responsible for higher-level cognitive functions.
Step-by-step explanation:
The four general categories of the frontal cortex include:
- The primary motor cortex, located in the precentral gyrus, which is responsible for the initiation of voluntary movement.
- The premotor cortex, which is involved in the planning and coordination of complex movements.
- Broca's area, associated with the production of speech and language processing.
- The frontal eye fields, involved in the control of eye movements.
Anterior to these motor-related areas is the prefrontal cortex, which is essential for judgment, abstract reasoning, and working memory, playing a significant role in decision-making and executive functions.
