Summary:
In the visual perception: neural processing chapter it first started talking about how neurons work and what parts make up the neurons. The neurons contain three parts which are dendrites, axon, and the axon terminal. Dendrites are the structures that receive electrical messages from other neurons. In order for neurons to work, they will have to receive stimuli through their synaptic receptors. Once the dendrites receive the electrical messages from the other neurons it will transfer it to the axon which will convey the electrical messages through a distance to the axon terminal. The axon has myelin sheaths that help insulates it and speed up the electrical messages. The axon terminal then transmits the messages to different neurons throughout the body.
An action potential is caused by ions moving in and out of the axon; these ions are sodium and potassium. Depolarization causes the inside of the axon to be more positive and hyperpolarization causes the inside to be more negative. “The …show more content…
I was very intrigued on how neurons work and receive information. From taking biology and society I have known about neurons but have forgotten about it because I have not used the knowledge I have learned in a while. It still surprises me how we process and see stuff because we used our eyes day to day without actually asking why or how it work unless we learn or research it. One concept or phenomenon that still interested me is the Hermann grid illusion. From reading the articles, “Making Sense of the Hermann Grid Illusion”, by Sarah Ross. It has made more sense on how our eyes actually process the Hermann Grid illusion and why the dark spots disappear when you look directly at it. It was a bit confusing when Ross explain the receptive field of the ganglion cell because she didn’t explain why the two excitatory cancel out with two
