Use the terms in order to correctly describe the sequence of events involved in your example of visual perception. -thalamus -retina -pupil -transduction action -potential feature -detector -excitatory neurotransmitter

Answer 1

Use the following terms to describe in detail how you visually perceive an object that you can see right now.

Answer: To see for example an apple first light that passes through the pupil is eventually reflected on the pupil, activating neurons in the retina. light waves that were reflected off the apple are changed into neural impulses (transduction) at the point of the retina, where neurons fire in response to light waves. Action potentials are released when neurons fire, sending an electrical charge through the neuron. Excitatory neurotransmitters are released when the action potential reaches the axon terminal, and that these neurotransmitters increase the chances that the next neuron will fire. Of course the neural message from the retina first passes through the thalamus, and then the thalamus routes the impulse elsewhere in the brain.

I hope it helps, Regards.
