Document Summary
3d x ray image produced using an x-ray camera and source that rotates around the patient"s head computer reconstructs 3d image from scans. Problems: 1) measuring oxygen 2) slow 3) in the resolution of 1 mm, there are thousands and thousands of neurons active. You"re not actually measuring electrical signals (with above). Gross anatomy of the nervous system subdivisions. Central nervous system: brain and spinal cord. Dorsal (top surface, belly) + ventral (back, upwards if you were a cockroach: bend in central nervous system. Caudal = close to tail + rostral =opposite of caudal. Forebrain is dominated by cerebral cortex/ cerebral hemispheres cerebral cortex = layered tissue, highly folded sheet lateral fissure = big gyrus cerebellum (greatly folded) Parietal lobes somatosensory (touch, joint position, mechanical info from the body, temperature, pain) Frontal lobe most mysterious, planning of movements, associating information from centers, planning and coordination.
