00:00:04.000 --> 00:00:10.000
Now that the electrode is in the brain, what can you do with it?

2
00:00:10.000 --> 00:00:15.000
There are two basic procedures; stimulation and destruction

3
00:00:15.000 --> 00:00:21.000
Stimulation uses a weak electrical current to activate the neurons in the target brain region

4
00:00:21.000 --> 00:00:26.000
causing them to fire and send their signals to influence the rats behavior.

5
00:00:27.000 --> 00:00:32.000
Destruction uses a stronger electrical current to destroy the brain structure

6
00:00:32.000 --> 00:00:37.000
The target region can no longer actively influence behavior

3
00:00:37.000 --> 00:00:42.000
but the rats behavior will change because that brain region is no longer present
