    Study Notes

    Brain Structure Overview

    • The brainstem comprises the medulla and pons, responsible for automatic survival functions such as breathing and heartbeat regulation.
    • The medulla manages essential life-maintaining processes; the pons connects the spinal cord to the brain and is involved in the sleep-wake cycle.
    • Reticular formation regulates arousal and consciousness; damage may lead to coma.
    • The thalamus, located atop the brainstem, acts as the brain's sensory control center for all senses except smell.
    • The cerebellum controls fine motor skills, coordination, posture, and balance and is sensitive to alcohol, affecting movement.

    Limbic System Functions

    • The limbic system processes emotions and long-term memory, including the amygdala, hippocampus, and hypothalamus.
    • Amygdala manages emotional responses, especially fear and aggression, activating the fight-or-flight response.
    • The hippocampus converts information into long-term memory; vulnerable to Alzheimer's disease.
    • The hypothalamus oversees the autonomic nervous system, regulating body temperature, hunger, thirst, and sexual behaviors. The lateral hypothalamus controls hunger, while the ventromedial hypothalamus regulates feelings of fullness.

    Cortical Areas and Their Functions

    • The cerebral cortex features two hemispheres, with specialized roles across its lobes.
    • The frontal lobe contains the prefrontal cortex (judgment, planning, personality) and the motor cortex (voluntary movements). Broca's area is crucial for speech production.
    • Damage to the prefrontal cortex (e.g., Phineas Gage incident) can drastically change personality and emotional control.
    • Parietal lobes process sensory information from the body (touch, pain, temperature) and spatial orientation; the somatosensory cortex aids in registering body sensations.
    • Temporal lobes are responsible for hearing, language processing, and retaining long-term memories. Wernicke’s area is instrumental in understanding spoken language.

    Visual Processing and Brain Communication

    • The occipital lobes process visual information; damage may lead to vision impairment or blindness.
    • The corpus callosum connects the brain's hemispheres, facilitating communication between them.

    Brain Lateralization

    • The brain is lateralized, with the left side controlling the right side of the body and vice versa.
    • Left hemisphere handles speech, language, and logical reasoning; right hemisphere manages spatial abilities and emotional expression.

    Neuroplasticity and Brain Damage

    • Plasticity refers to the brain's capacity to reorganize itself after damage and form new pathways based on experience.
    • Severed neurons in the brain and spinal cord cannot regenerate, but some brain tissues can adapt post-injury.
    • Neurogenesis allows for new neuron formation, mainly occurring in areas associated with memory and olfaction.

    Brain Imaging Techniques

    • EEG (Electroencephalogram) measures electrical activity in the brain, useful for identifying seizures.
    • PET Scan uses radioactive glucose to reveal active brain regions, instrumental in diagnosing disorders.
    • CT Scan employs X-rays to examine brain structure and identify tumors or injuries.
    • MRI (Magnetic Resonance Imaging) generates detailed images of brain tissues and abnormalities using magnetic fields.
    • fMRI (Functional MRI) assesses brain functions by tracking blood flow, offering precise insights compared to PET scans.
