Flashcards in Chapter 4 Deck (16):
Modify the energy created by something in the environment; ears, eyes, etc.
Process of converting incoming energy into neural activity.
Detect certain forms of energy; primary afferent neurons
Responsiveness to an unchanging stimulus decreases over time.
Translation of the physical properties of a stimulus into a pattern of neural activity that specifically identifies those physical properties.
Timing of firing
Location of firing
Ear; where transduction occurs
Axon going to the brain
-Cornea: transparent protective layer
-Pupil: opening behind cornea
-Iris: color of the eye, controls the size of the pupil
-Retina: back of the eye
Concert light energy into neural activity; contain photopigments, chemicals that respond to light
Cells that generate action potentials capable of traveling the distance between the eye(retina) to the brain.
Allows us to know about where we are and what each part of our body is doing.
