Sensory Neuroscience: Quiz 1

Behavior

Action preformed in response to stimulus

Sensations

Fundamental, elementary components of an experience

Perception

Processes used to arrive at a meaningful interpretation of sensations

Stimulus

Something that elicits a response (the 5 senses)

3 types of sensory processes

Reception, transduction, and coding

Reception

Involves environmental stimulus (tree) and transformation (Light reflecting off tree into eye)

Vision

light waves (photoreceptors)

Audition

sound waves (hair cells)

Touch

touch/pain receptors, pressure, temperature, chemicals (mechanoreceptors)

Smell

chemically activated (olfactory receptors)

Taste

chemically activated (taste buds)

Transduction

Sensory receptors change the stimulus energy into an electrochemical neuronal change

Coding

Neural processing is the correspondence between stimulus features and neuronal activity

Vision info coded...

occipital lobe

Hearing info coded...

temporal lobe

Touch info coded...

parietal lobe

Smell info coded...

temporal lobe

Taste info coded...

insula

Psychophysics

Relationship between stimuli and behavioral response

Physiological

Relationship between stimuli and physiological response & relationship between physiological response and behavioral response
