PS102 Lecture Notes - Lecture 3: Optic Nerve
Document Summary
The process through which the senses detect visual, auditory, and other sensory stimuli and transmit them to the brain. The process by which sensory information is actively organized and interpreted by the brain. Example the eye blind spot where the optic nerve is and where that spot is, we have no photo receptors. Sensory transduction = converting information in environment into neural impulses. How much stimulation has to be out there before we can detect that it is there. Thresholds the second you detect something, it is available for you to focus on. The difference between not being bale to perceive a stimulus and being able to just barely perceive it. The minimum amount of sensory stimulation that can be detected 50% of the time. The smallest increase or decrease in a stimulus that is required to notice a difference. Difference that is detectable 50% of the time. Become less sensitive to an unchanging sensory stimulus over time.
