In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly. d. Attention-deficit/hyperactivity disorder (ADHD) A really cool thing about the lens is that it reflects the light upside down and inverted toward the back of the eye (retina). The somatic nervous system consists of afferent nerves or sensory nerves, and efferent nerves or motor nerves. Retinal Processing Visual signals leave the cones and rods, travel to the bipolar cells, and then to ganglion cells. We have the word sideburns because Ambrose Burnside had bushy whiskers. (authoritative was most effective), focused on positive interpretations of stressful situations, a neurotransmitter that enables learning and memory and also triggers muscle contraction (not enough = alzheimers), too much = schizophrenia, too little = Parkinson's disease, A major excitatory neurotransmitter; involved in memory. c.
