  • Found in the occipital lobe
  • Processes visual information and performs initial image analysis

Visual Association Area

  • Surrounds primary visual cortex
  • Interprets complex visual information and stores visual memories

Auditory Cortex

  • Located in the temporal lobe
  • Processes basic auditory information and sound recognition

Auditory Association Area

  • Adjacent to primary auditory cortex
  • Analyzes complex sound patterns and language comprehension

Prefrontal Cortex

  • Occupies the anterior portion of the frontal lobe
  • Handles executive functions, personality, and complex decision-making

Broca’s Area

  • Located in the inferior frontal gyrus
  • Essential for speech production and language expression

Wernicke’s Area

  • Situated in the posterior temporal lobe
  • Critical for language comprehension and semantic processing

Functional Systems

Sensory Processing

The brain processes sensory information through hierarchical networks. Initial processing occurs in primary areas before integration in association regions. This organization allows for both basic and complex information processing.

Motor Control

Motor function involves multiple areas working in concert. The system includes:

  • Primary motor planning
  • Movement coordination
  • Fine motor control
  • Balance and posture maintenance

Language Network

Speech Production

  • Broca’s area coordination
  • Motor speech planning
  • Articulation control
  • Prosody regulation

Language Comprehension

  • Wernicke’s area processing
  • Semantic analysis
  • Syntactic interpretation
  • Phonological processing

Executive Function

Cognitive Control

  • Attention regulation
  • Decision making
  • Working memory
  • Behavioral inhibition

Clinical Significance

Neurological Assessment

Understanding functional anatomy is essential for:

  • Localizing lesions
  • Evaluating stroke effects
  • Monitoring recovery
  • Planning surgical approaches

Common Pathologies

  • Stroke syndromes
  • Epilepsy foci
  • Traumatic injuries
  • Neurodegenerative conditions

The intricate organization of brain functional areas underlies all human behavior and cognition. Continued research advances our understanding of these complex neural networks and their clinical implications.
