Why weren't you able to successfully identify all the flavors of candy when your nose was plugged? The sensory neurons from our taste buds are routed through our olfactory epithelium before being interpreted in the brain. O Taste and smell are interpreted in the same area of the brain, so if 1 sense is not working properly, then the other sense won't work either. The flavor of food that we interpret in our brain is composed of sensory information from both our taste buds and our olfactory cells.

You discover that the convergence ratio for the photoreceptors in the Zerons is opposite to that of humans, i.e the convergence ratio for rods is lower and the convergence ratio of cones is higher. The site and distribution of the photoreceptors is the same as in humans. Question: What might be true for Zerons vision? The images formed in the dark are sharper than those formed in light The central parts of their visual field aren't as sharp as the peripheral parts of their visual fields. They are better at forming color contrasts in images They have poor differentiation between black and white
As light hits the rods and cones, they release molecules. This is interpreted as light by the brain. None of these is correct More neurotransmitter molecules More opsin molecules More rhodopsin molecules Fewer neurotransmitter molecules
Events in Visual Perception Potassium channels open. Potassium ions move out of the neuron. Some sodium channels open in the neuronal membrane of the dendrite. All ion channels close and the Na+/K+ exchange pump starts working. Some sodium ions diffuse into the neuron membrane of the dendrite. Lights hit the retina. The threshold level is reached at the neuronal membrane of the dendrite. The remaining sodium channels open. Sodium ions move into the neuron. List, in order, the events in visual perception that must occur for a person to see an object:
