Why does the brain interpret both positive and negative signals? - Answer What matters is that there is a change (+/-). As long as circuitry is set up to respond to that change. Dark Current - Answer In dark PRC, CNGC open because cGMP is around to open them = increase in Ca and Na and decrease in K because pumps. Ca and K come in = depolarization. Light causes hyper polarization Why does visual system start out depolarized? - Answer want visual system to be fast. So in the dark, rel...

Neurophysiology of Nerve Impulses. Physioex 3 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. - correct answer Increasing the extracellular K+ reduces the steepness of the concentration gradient and so less K+ diffuses out of the neuron. 2. Explain why increasing the extracellular K+ causes the membrane potential to change to a less negative value. - correct answer The membrane potential became less negative because l...

ANA 442 Exam 2 (Answered) 2022 Graded A+ 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 b...
