Document Summary
Sulci, gyri and fissures used as landmarks. 4 major lobes (plus limbic lobe), defined by prominent anatomical marks. Longitudinal fissure (not in view) separates the two cerebral hemispheres. Central sulcus separation of frontal and parietal lobe. Lateral fissure separation of temporal lobe from frontal and parietal. Parietal-occipital sulcus separation of occipital lobe and parietal lobe. Analyzes visual information received from the eyes. Analyzes auditory information received from the ears. Analyzes body sense information received from the body (pain, sensitivity, etc - from the arms, face, etc) Sensory information (except for olfaction and gustation) & motor control is processed in the contralateral hemisphere. Primary cortex: primary projection fields of the sensory input pathways. Typically doing the higher level processing (learning, planning, memory, etc) Can be unimodal (one sense) or multimodal (many senses) A collection of nuclei (groups of neurons) Largely involved in the control of movement. Also involved in other things (e. g. habit forming) Sends information to different parts of cortex.
