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.

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.
