Colorful World Analysis

Colorful World Tutorial

To summarize what I learned in the Colorful World tutorial, the current theory of color vision come from the two predominant scientific theories from Hering’s and Young-Helmholtz. The two theories have been combined to create the current unified theory of color vision that the first stage of color processing incorporates the trichromatic theory on how color is processed through cones and the second stage involves the opponent processing theory.

Our tutorial and our text go into a great deal of detail on the dynamics of color vision and how we experience color. Our text states that “Our perception of color is primarily determined by the wavelength of light that an object reflects”. Furthermore, “our perceptions of

Carry those impulses to the proper location in the brain

4. Process the information contained in the pattern of impulses so that the stimulus can be identified

The first two tasks are performed by the ear which is broken down into three section outer, middle and inner. In order to hear sound waves must be able to detect changes in air pressure surrounding the eardrum.

The tutorial gives us the same information provided in our text but provides additional graphs that are helpful. Our text provides a good summation of the auditory system or hearing “results when sound waves are collected in the outer ear, amplified in the middle ear, and converted to neural messages in the inner ear.

You’re Mind on Drugs

The You’re Mind on Drugs tutorial was about psychoactive drugs and the impact that the drugs have on the mind and body. In order for a psychoactive drug to take effect it has to enter into the bloodstream through ingestion, inhalation, absorption, or injection. Once in the bloodstream the psychoactive drugs influence our behavior by altering the functioning of the central nervous system. The drug Wear’s off over time as the liver produces enzymes that metabolize the

We spend about one third of our lives sleeping. There are three stages of sleep light sleep, deep sleep, REM sleep (rapid eye movement). We can study the stages of sleep and brain activity by using an EEG which monitors brain activity. While we sleep the mind is still active and we have sleep thoughts and true dreams that occur depending on the stage of sleep that we are in. I this tutorial I found the explanation of why we sleep to be the most interesting aspect of the study that the purpose of sleep is like internal housekeeping without distraction. It gives our body and mind an opportunity to process and organize our thoughts and is essential to our survival. We cannot live or be healthy without an adequate amount of
