Neural transduction - Study guides, Class notes & Summaries

adaptation correct answers a reduction in response caused by prior or continuing stimulation. Similar to habituation, where you become less sensitive to it sensory transduction correct answers the conversion of physical energy (light) into neural energy by sensory receptors (sensory organs) dualism correct answers the idea that the mind has an existence separate from the material world of the body materialism correct answers the idea that the only thing that exists is matter, and that a...

Retina layer of neurons in the back of the eye What is transduction? the process of turning light into neural signals, takes place in the retina What does the cornea do? - bends light (refraction) and forms image on the retina What does the lens do? Focuses light onto retina What are the ciliary muscles? they adjust the focus by changing the shape of the lens What is accommodation of the eye? The process of changing the shape of the lens to focus on near or distant objects (by ciliary m...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...

If a brick falls in the woods and no one is around to feel it, does it make a pain? Answer NO How many senses (approximately) does a typical human have? Answer 12 What is the physical stimulus that vision detects? Answer LIGHT What is the physical stimulus that audition (hearing) detects? Answer Vibrations (in air) What is the physical stimulus that olfaction (smell) detects? Answer molecules Which of these areas of research/industry require a knowledge of perception? Answer All o...

What is a specialized cell that responds to a particular energy or substance in the internal or external environ, & converts this energy into a change in the electrical potential across its membrane? - Answer receptor cell What is the concept that each nerve input to the brain reports only a particular type of info? - Answer labeled lines What is transduction? - Answer translation of an external stimulus into a neural signal What is the external stimulus for touch? - Answer ...

Psychology 2301 Collin College - Questions with complete solution Psychology 2301; Chapter 4(sensation and perception) review Understanding Sensation - correct answer -While your brain floats in complete silence and darkness, your body is bombarded with stimuli from outside. -Sensing the stimuli is not enough. our brains must receive, convert, and adapt the information into meaningful representations of the world. Sensation - correct answer Process of detecting, converting, and transm...
