association cortex cortical area that integrates information for multiple sensory systems blue on bipolar cell an on-bipolar cell selectively connects to S cones, activated by short WL light and is inhibited by longer WL light Center-surround A property of a visual system neuron's receptive field in which light in the receptive field center and light just outside of the receptive field center are antagonistic. The concept has also been extended beyond the visual system. chromophore The l...

Which of the following statements about action potentials is FALSE? X The magnitude of the AP is proportional to the magnitude of the stimulus that evoked it - APs are initiated only when the membrane potential rises above a threshold. - APs can be propagated along neuronal processes with little or no decay. - APs can sometimes propagate in dendrites, in addition to axons. Actin filaments: - Can cause membrane protrusions responsible for cell shape changes and cell movement - Interact wit...
