Mirror Neurons |
A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in primate species. |

Purkinje fibers. Where are they found? |
Purkinje Fibers are found in Cerebellum |
|
|
Dendrites transmit electric signals ___________ (towards/away from) the cell body. |
towards |
|
|
Unipolar Neurons |
Unipolar (or Pseudo-unipolar) neurons haveoneprocessfrom the cell body. However, that single, very short, process splits intolonger processes (a dendrite plus an axon). Unipolar neurons are sensoryneurons - conducting impulses into the central nervous system. |
