Brain Regions & Cranial Nerves Lobes - Frontal — personality, judgment, motor (precentral gyrus), Broca's speech. - Parietal — sensation. - Temporal — hearing, memory, Wernicke's speech. - Occipital — vision. - Cerebellum — coordination, balance. - Brainstem — vital centers (breathing, HR, BP).
Cranial nerves — On Old Olympus… 1. Olfactory · 2 Optic · 3 Oculomotor · 4 Trochlear · 5 Trigeminal · 6 Abducens · 7 Facial · 8 Vestibulocochlear · 9 Glossopharyngeal · 10 Vagus · 11 Accessory · 12 Hypoglossal.
Stroke language deficits - Left hemisphere stroke — right-sided weakness + aphasia (Broca expressive / Wernicke receptive). - Right hemisphere stroke — left-sided weakness + neglect, impulsivity.
Glasgow Coma Scale - Eye (1–4), Verbal (1–5), Motor (1–6). ≤ 8 = intubate.
