Study Notes
Chapter 3: Brain Lobes and Ventricular System
- Frontal lobe: Contains the motor cortex (voluntary movement), prefrontal cortex (higher-level cognitive functions), Broca's area (speech production).
- Parietal lobe: Contains the somatosensory cortex (touch, temperature, pain), spatial processing areas.
- Temporal lobe: Contains the auditory cortex (hearing), Wernicke's area (speech comprehension), hippocampus (memory), amygdala (emotion).
- Occipital lobe: Contains the visual cortex (vision).
- Cerebrospinal fluid (CSF) functions: Cushions the brain, removes waste products, helps regulate intracranial pressure.
- Ventricular system: A network of cavities within the brain filled with CSF. Ventricles are located in the cerebral hemispheres and brainstem.
- Choroid plexus: A network of capillaries and ependymal cells that produce CSF.
- CSF flow order: Lateral ventricles → third ventricle → cerebral aqueduct → fourth ventricle → subarachnoid space.
- The central sulcus divides the frontal lobe from the parietal lobe.
Chapter 2: Neuron Structure
- Basic neuron structures: Soma (cell body), dendrites (receive signals), axon (transmits signals), axon terminals (release neurotransmitters).
Chapter 4, 5, 19: Neuroimaging
- Computed tomography (CT): Uses X-rays to produce detailed images of brain structure.
- Magnetic resonance imaging (MRI): Uses magnetic fields and radio waves to create brain images.
Chapter 3: Brain Lobes and Ventricular System
-
Frontal lobe cortex: Higher-level cognitive functions, voluntary movement.

Parietal lobe cortex: Processing sensory information (touch, temperature, pain, spatial awareness).
-
Temporal lobe cortex: Auditory processing, memory, language comprehension.
-
Occipital lobe cortex: Visual processing.
-
Cerebrospinal fluid (CSF) functions: Cushioning the brain, removing waste products, maintaining stable brain environment.
