week 1 - intro to sensory neuroscience Flashcards
What is needed in order to “build” experience?
sensation and perception
sensation
most basic and fundamental components of an experience
perception
the processes used to arrive at a meaningful interpretation of sensations
What are the 3 steps in the sensory process?
- reception
- transduction
- coding
reception
presentation of a stimulus causes sensory receptors to activate
transduction
the conversion/translation of stimulus energy into an electrochemical neuronal change
coding
involves neural processing which is the correspondance between stimulus features and neuronal activity
What are the types of behavioral responses to the sensory process?
- perception
- recognition
- action (behavior)
What two methods are used to study perception?
psychophysical and physiological approaches
psychophysical approach
measures relationship between the stimuli and the behavioral response
physiological approach
- measures relationship between stimuli and physiological response
- measures relationship between physiological response and behavioral response
