Document Summary

Goal reach out and grab an object. Reference mechanism how correct you are at performing the acivity (something you compare to) Execuive level brain is specifying neuro-motor signals. Efector level instrucions from motorneuron level as to what to do/what to move. If there"s error associated with movement will be detected in comparison between environment and reference mechanism. Vision, propriorecepive system muscle spindles, and golgi tendon organs, vesibular system. Pathways aferent commands to some region in your brain (sensory informaion) informaion is monitored and evaluated at the level of cerebral cortex transferred into an eferent command, descend down the spinal cord and tell the muscles how to move. Vision basic schemaic of the visual system three main pathways: everything starts in the reina (eye), goes to the cns lgn (lateral geniculate nucleus), subcorical structure in the thalamus v1 (primary visual cortex) geniculostriate. Cornea; outer most layer of the eye, deicit; cannot relect light properly, impacts ability to see clearly.
