| NATURE OF NEURAL
ACTIVITY IN UTERO??? |
|
|
|
|
| In the embryo, neighboring ganglion cells
fire together |
|||
| in synchronous bursts or “waves” |
|||
| This spontaneous but synchronous firing of
retinal afferent fibers excites |
|||
| a group of target neurons in the LGN, and
strengthens those synapses. |
