Chapter 8: General Principles of Sensory Processing, Touch, and Pain

1. sensory receptor act as filters of the environment; detect and respond to
organs some events but not others

2. stimulus an event that affects the sensory organ

3. receptor cells are within the organs and detect particular kinds of stimuli
and convert them into the language of the nervous system
(electrical signals)

4. adequate signals the type of stimulus for which a given sensory organ is
particularly adapted

5. doctrine of spe- states that the receptors and neural channels for the differ-
cific nerve ener- ent senses are independent and that each uses a different
gies nerve "energy"
Muller thought that different receptor organs might each
use a different type of energy to communicate with the
brain and that the brain knew which type of stimulus had
happened by which type of energy was received

6. labeled lines different senses all use the same type of energy (action
potentials)
particular neurons are at the outset labeled for distinctive
sensory experiences

7. sensory trans- the process in which a receptor cell converts the energy in
duction a stimulus into a change in the electrical potential across
its membrane

8. receptor poten- a local change in the resting potential of a receptor cell that
tial mediates between the impact of stimuli and the initiation
of nerve impulses
similar to an EPSP or IPSP being generated

9. Pacinian Corpus- receptor that detects vibration and provides information
cle about the texture of an object
it consists of an axon surrounded by a structure that
resembles a tiny onion because it has concentric layers
of tissue
mechanical stimuli produce a graded potential with an
