    Study Notes

    The Human Brain

    • The brain has a wrinkly surface with bumps and folds, allowing for a greater surface area, more neurons, and increased cellular mass.

    Cerebral Cortex

    • The cerebral cortex is the outer portion of the brain and can be divided into four hemispheres: frontal, parietal, occipital, and temporal lobes.

    Frontal Lobe

    • The frontal lobe is responsible for motor movements and executive functions such as thinking, problem-solving, and supervising other brain areas.
    • The motor cortex or motor strip is a part of the frontal lobe, controlling body movements and allowing for electric stimulation to make specific body parts move.
    • The prefrontal cortex is also part of the frontal lobe, responsible for executive functions, thinking, and problem-solving.
    • Broca's area is a part of the frontal lobe, associated with speech production.

    Parietal Lobe

    • The parietal lobe is important for tasks such as spatial processing and manipulation, allowing for understanding of three-dimensional space.
    • The somatosensory cortex is part of the parietal lobe, receiving information from the body about touch, pressure, temperature, and pain.
    • The sensorimotor cortex is a combination of the motor cortex and somatosensory cortex, working together to enable movement and sensation.

    Occipital Lobe

    • The occipital lobe is responsible for vision processing, with information collected from the eyes transported to the back of the brain for processing.
    • The striate cortex is a term used to describe the striped appearance of occipital lobe cells under a microscope.

    Temporal Lobe

    • The temporal lobe is responsible for auditory processing, with information collected from the ears transported to the brain for processing.
    • Wernicke's area is a part of the temporal lobe, responsible for language reception and comprehension.

    The Human Brain

    • The brain's surface is wrinkly with bumps and folds, increasing its surface area, allowing for more neurons, and boosting cellular mass.

    Cerebral Cortex

    • The cerebral cortex is the outermost layer of the brain, divided into four main regions: frontal, parietal, occipital, and temporal lobes.

    Frontal Lobe

    • The frontal lobe oversees motor movements and executive functions, including thinking, problem-solving, and regulating other brain regions.
    • The motor cortex, responsible for controlling body movements, is located in the frontal lobe and can be stimulated electrically to move specific body parts.
    • The prefrontal cortex, also part of the frontal lobe, is responsible for executive functions, thinking, and problem-solving.
    • Broca's area, a region in the frontal lobe, plays a key role in speech production.

    Parietal Lobe

    • The parietal lobe is essential for spatial processing and manipulation, enabling understanding of three-dimensional space.
    • The somatosensory cortex, part of the parietal lobe, receives sensory information from the body about touch, pressure, temperature, and pain.
    • The sensorimotor cortex, a combination of the motor cortex and somatosensory cortex, works together to facilitate movement and sensation.

    Occipital Lobe

    • The occipital lobe is dedicated to processing visual information, receiving data from the eyes and processing it at the back of the brain.
    • The striate cortex, characterized by its striped appearance under a microscope, is a region within the occipital lobe.

    Temporal Lobe

    • The temporal lobe is responsible for processing auditory information, receiving data from the ears and processing it in the brain.
    • Wernicke's area, located in the temporal lobe, is essential for language reception and comprehension.
