  • Forebrain
    Most evolutionarily advanced brain region, responsible for logic, rational thought, and complex cognitive functions.
  • Cerebrum
    Largest brain part, divided into two hemispheres, governing higher-order thinking, memory, and voluntary actions.
  • Corpus Callosum
    Thick bundle of nerve fibers connecting the left and right cerebral hemispheres, enabling communication between them.
  • Frontal Lobe
    Front brain region involved in voluntary movement, executive functions, inhibitory control, and speech production.
  • Primary Motor Cortex
    Area within the frontal lobe that initiates and controls voluntary muscle movements.
  • Broca's Area
    Region near the motor cortex essential for producing spoken language and coordinating speech muscles.
  • Temporal Lobe
    Side brain region near the ears, crucial for processing auditory information and language comprehension.
  • Wernicke's Area
    Temporal lobe region vital for understanding spoken and written language.
  • Parietal Lobe
    Upper middle brain region processing touch, spatial awareness, and internal body sensations.
  • Primary Somatosensory Cortex
    Parietal lobe area receiving and interpreting sensory information from the body, such as touch and proprioception.
  • Occipital Lobe
    Rear brain region dedicated to visual processing and interpretation.
  • Basal Ganglia
    Subcortical structures regulating movement initiation, inhibition, and coordination with the motor cortex.
  • Thalamus
    Central relay station for sensory signals, also involved in consciousness and sleep regulation.
  • Limbic System
    Group of structures managing emotion, memory, and homeostasis, including the hypothalamus, amygdala, and hippocampus.
  • Cerebellum
    Hindbrain structure resembling a small brain, responsible for coordination, balance, and precise motor control.
