    Study Notes

    Brain Structures

    • The midbrain, also called mesencephalon, is composed of the tectum and tegmentum and serves important functions in motor movement, particularly eye movements, and auditory and visual processing.
    • The midbrain is located within the brainstem and is relatively small compared to the forebrain and hindbrain.

    Hindbrain Structures

    • The hindbrain, also called rhombencephalon, is composed of the medulla oblongata, pons, and cerebellum.
    • The hindbrain coordinates functions fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness.

    The Two Hemispheres

    • The left hemisphere of the brain is responsible for controlling the right side of the body.
    • The left hemisphere performs tasks related to logic, such as in Science and Mathematics.
    • It contains the motor cortex, prefrontal cortex, and Broca's area.

    Lobes of the Brain

    • The parietal lobe is located behind the frontal lobe and is involved in processing information from the body's senses.
    • The somatosensory cortex, essential for processing sensory information, is located within the parietal lobe.
    • The temporal lobe is associated with hearing, memory, emotion, and some aspects of language.
    • The auditory cortex, responsible for processing auditory information, is located within the temporal lobe.
    • The occipital lobe contains the primary visual cortex, responsible for interpreting incoming visual information.

    The Limbic System

    • The limbic system regulates temperature, heart rate, blood pressure, and blood sugar.
    • The hippocampus and amygdala assist in forming memories.
    • The limbic system is the center of emotions.
    • Nerve impulses to the amygdala activate emotions such as anger, fear, and aggression.

    Brain Development

    • Self-control improves as adolescence become more capable of judging cause and effect.
    • More sections of the brain become involved in managing emotions, and teenagers become better at understanding other emotions.

    Brain Facts

    • The brain is a complex organ made up of mutually dependent parts, each with its precise purpose.
    • The brain consists of at least 60% fat.
    • The forebrain is the largest part of the brain.
    • The brain has three important sections: forebrain, midbrain, and hindbrain.
