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
