What is the purpose of both feed foward and feed back inhibition?
|
improve spatial localization
|
|
How does feed forward inhibition work?
|
adjacent inhibitory neurons vs excitatory
|
|
How does feed back inhibition work?
|
increases polarization so stronger input required for AP
|
|
What are teh 3 types of temporal sensory input?
|
1. motion sensitive cells
2. direction sensitive cells 3. orientation sensitive cells |
|
Describe motion sensitive cells
|
AP whenever something moves over, location/direction doesn't matter
|
|
Describe direction sensitive cells
|
AP when go in one direction, ie. distally/towards ulnar
|
|
Describe orientation sensitive cells
|
AP when going in a certain axis (ie across phalanges)
|
|
What is spatial sensory input?
|
signle cell is only activated within a certain receptor field, no other cell is activated
