Document Summary
Spinal cord: loss sensation but motor function is not lost if dorsal roots are cut; dorsal = sensation information, maintained sensation but lost motor function if ventral roots are cut; ventral = motor information. Cns: ventricles, filled with cerebral spinal fluid (csf, part of cns, moves and shunts hormones throughout the brain, narcoleptic people lack hormone circulation, meninges, dura mater = covering of the brain, arachnoid membrane = second layer, pia matter. Imaging: computed tomography (ct/cat, mri, diffusion tensor imaging, can look for things such as tumors or stroke damage, anatomical and structural physiology, pet, fmri or eeg/erp. Neuroanatomy ii: sulci: small grooves, gyri: ridge of the cortex, bumps regarding the function of the brain, highly conserved trait across all animals, fissures: large grooves in cortex, divide the cortex in half and into sub-regions. Diffusion tension imaging: looks at the density of the tissue.
