    Study Notes

    Brain Functions and Anatomy

    • Broca's area in the frontal lobe is primarily responsible for language production.
    • Each hemisphere of the cerebrum contains four lobes: frontal, parietal, temporal, and occipital.

    Basal Ganglia and Language Disorders

    • The basal ganglia play a critical role in movement regulation, motor control, and cognitive functions.
    • Aphasia refers to a language disorder affecting speech production or comprehension, typically due to brain damage.

    Brain Function Theories

    • The equipotentiality view suggests that different areas of the brain can take over functions if certain areas are damaged, emphasizing brain plasticity.

    Neuroimaging Techniques

    • fMRI (functional magnetic resonance imaging) measures brain activity by detecting changes in blood flow, offering advantages over EEG (electroencephalography) and MEG (magnetoencephalography) such as better spatial resolution.
    • Neurotransmitter concentration measurement, rather than blood flow, is the focus of Magnetic Resonance Spectroscopy (MRS).
    • A major challenge of EEG and MEG is pinpointing the precise source of signals due to the complex nature of the electrical activity.

    Measuring Brain Activity

    • fMRI utilizes BOLD (Blood Oxygen Level Dependent) contrast to visualize active and less active brain regions.
    • Event-Related Potentials (ERP) are beneficial for studying neural activity as they provide high temporal resolution, allowing detection of rapid brain responses to stimuli.
