Here are detailed lecture notes from the provided lecture transcript:
I. Overview of Brain Anatomy
A. Cerebral Cortex
1. Divided into lobes: frontal, parietal, temporal, occipital
2. Insular lobe - hidden deep within lateral sulcus between temporal and frontal/parietal lobes
B. Functional Areas
1. Frontal lobe - primary motor cortex
2. Parietal lobe - primary somatosensory cortex (touch, pain, body position)
3. Temporal lobe - primary auditory cortex
4. Occipital lobe - primary visual cortex
5. Most of visual cortex on medial surface, some motor/sensory on medial surface
II. Brain Divisions A. Spinal Cord 1. Sacral - innervates pelvic region 2. Lumbar - innervates legs 3. Thoracic - innervates trunk 4. Cervical - innervates arms B. Hindbrain 1. Medulla 2. Pons 3. Cerebellum (located dorsally) C. Midbrain D. Diencephalon 1. Hypothalamus 2. Thalamus E. Telencephalon 1. Cerebral cortex (outer mantle) 2. Amygdala (processing fear) 3. Basal ganglia (action selection)
III. Telencephalon Components A. Cerebral Cortex 1. Outer mantle covering brain B. Amygdala 1. Important for fear processing/perception C. Basal Ganglia 1. Selects which actions to take 2. Decides which muscles to activate
