Human Brain Anatomy and Function

Overview

  • The human brain has various parts, each responsible for different functions.
  • This discussion focuses on the cerebral cortex, the outer portion of the brain, which is wrinkled to increase surface area and accommodate more neurons.

Cerebral Cortex Lobes

  • Frontal Lobe

    • Located at the front of the brain.
    • Composed of:
      • Motor Cortex: Controls body movements. Stimulation can cause physical reactions like twitches.
      • Prefrontal Cortex: Involved in executive functions such as thinking, problem-solving, and directing brain activities.
      • Broca's Area: Involved in speech production.
  • Parietal Lobe

    • Positioned at the top and back of the brain.
    • Functions include:
      • Somatosensory Cortex: Processes sensory information related to touch, pressure, temperature, and pain.
      • Involved in spatial processing and manipulation, helping understand one's position and surroundings.
      • Works closely with the motor cortex in what is referred to as the sensorimotor cortex.
  • Occipital Lobe

    • Located at the back of the brain.
    • Primarily responsible for vision processing.
    • Includes the Striate Cortex, characterized by its striped appearance under a microscope.
  • Temporal Lobe

    • Found at the sides of the brain.
    • Responsible for auditory processing.
    • Contains Wernicke's Area, crucial for language reception and comprehension.

Additional Notes

  • Each lobe has functions beyond those listed but these are the primary associations to consider.
  • The brain's lobes work together to integrate various sensory and motor functions, impacting overall cognitive and physical capabilities.
