Cerebellar Neurons Exhibit Surprising Level of Activity (IMAGE)
Caption
Researchers captured images of individual granule neurons (orange circle-like objects) in the cerebellum using laser two-photon microscopy. Each colored line represents the activity of a different neuron as a mouse learned to predict an imminent event -- a puff of air to the eye. The researchers found that, contrary to existing theories of cerebellar function, many neurons were active at once. The study indicates that the cerebellum carries a rich representation of messages arriving from outside the body as well as from other parts of the brain.
