deep within the lateral sulcus (linked to emotion or the regulation of the body's homeostasis); one of the 5 lobes
consists of cerebral cortex (motor areas); body regions with the greatest motor innervation occupy the largest areas of motor cortex (bigger = more motor neurons)
consists of cerebral cortex (sensory areas); body regions with highest densities of receptors occupy the largest areas of sensory cortex
of the sensory cortex; MRI (protons H+ respond to a magnetic field); EEG can detect on surface of brain and measures "synaptic potenetial" by electrical currents
functions: interpretation of auditory centers that receive sensory fibers from cochlea (inner ear) and interpretation and associate of auditory and visual information
composes majority of the diencephalon; acts as relay center for all sensory information (except olfactory) to the cerebrum
below the diencephalon; contains the corpora quadrigemina, cerebral peduncles, substantia nigra, and red nucleus
also known as medulla oblongata and consists of: all descending and ascending fiber tracts between spinal cord and brain must pass through the medulla, cardiac control center, & regulates respiration with the pons
Ascending Spinal Tracts
convey SENSORY information from cutaneous receptors, prooprioceptors, and visceral receptors to cerebral cortex; they cross-deliver (left to right and right to left)
Descending Spinal Tracts
pyramidal tracts descend directly without synaptic interruption from cerebral cortex to spinal cord and reticulospinal tracts (extrapyramidal)
