Study Notes
Precentral Gyrus
- Located just anterior to the central sulcus.
- Primary motor cortex.
- Responsible for voluntary motor movement.
Postcentral Gyrus
- Located just posterior to the central sulcus.
- Primary somatosensory cortex.
- Responsible for mediating the detection of physical sensation.
Parietal Lobes
- Located just posterior to the frontal lobes.
- Inferior border is the temporal lobe and the lateral fissure.
- Responsible for sensory detection, perception, and interpretation.
Temporal Lobes
- Located most inferior or caudal.
- Posterior border is the anterior occipital lobe.
- Responsible for audition (hearing), comprehension of language, and long-term memory.
Occipital Lobes
- Located most posterior.
- Responsible for the interpretation of visual stimuli from the optic pathways.
Insula
- Located deep within the lateral fissure.
- Covered by the frontal, parietal, and temporal lobes.
- Involved in basic survival mechanisms (taste, sensation of the viscera, autonomic and homeostasis functions).
- Also functions in emotional processing (empathy, self-awareness, and emotional regulation).
Frontal Lobes
- Borders are the lateral fissure and the central sulcus.
- Mediate cognition (intelligence, problem-solving, and short-term memory), expressive language, motor planning, mathematical calculations.
- The prefrontal lobe mediates executive functions (organization, planning, sequencing, and motivation), self-insight, and regulation of emotions and working memory.
- Development continues after birth and is not complete until late adolescence or early adulthood.
