Termini in questo insieme (17)

  • Cerebrum
    Largest brain region, comprising 80% of mass, responsible for higher cognitive functions and divided into two hemispheres.
  • Corpus Callosum
    Thick bundle of nerve fibers connecting the brain's hemispheres, enabling rapid interhemispheric communication.
  • Hemispheric Specialization
    Phenomenon where each brain hemisphere is optimized for distinct functions, such as language or creativity.
  • Contralateral Control
    Arrangement where each brain hemisphere governs the opposite side of the body for movement and sensation.
  • Cerebral Cortex
    Outer layer of the cerebrum, marked by gyri and sulci, crucial for complex thought and sensory processing.
  • Gyri
    Elevated ridges on the brain's surface, increasing cortical area within the skull for enhanced processing.
  • Sulci
    Shallow grooves separating gyri, contributing to the brain's wrinkled appearance and expanded surface area.
  • Frontal Lobe
    Front brain region involved in conscious thought, voluntary movement, speech, and executive functions.
  • Temporal Lobe
    Side brain region near the ears, essential for auditory processing, language comprehension, and memory.
  • Parietal Lobe
    Upper back brain region handling sensory input, spatial awareness, and proprioception.
  • Occipital Lobe
    Rear brain region dedicated primarily to visual processing and interpretation.
  • Primary Motor Cortex
    Frontal lobe area initiating voluntary muscle movements, mapped by the motor homunculus.
  • Primary Somatosensory Cortex
    Parietal lobe region processing touch, temperature, pressure, and body position sensations.
  • Broca’s Area
    Frontal lobe region crucial for coordinating the physical production of speech.
  • Wernicke’s Area
    Temporal lobe region essential for understanding spoken and written language.
  • Prefrontal Cortex
    Most anterior part of the frontal lobe, central to personality, planning, logic, and self-control.
  • Homunculus
    Distorted body map illustrating the proportional neural representation of body parts in sensory or motor cortices.
