1.   Hippocampal depth electrodes were placed stereotaxically.

2.   One coil electrode is placed at the SVC-RA junction and the second in the right ventricle.

3.   During ECT, a patient is anesthetized, and electrodes are placed on the head.

4.   Electrodes are already placed temporarily on the brains of candidates for resection, Schiff said.

5.   Electrodes are placed in auditory nerves to transmit signals detected by the implant.

6.   Electrodes were placed in monkey dopamine cells and the animals were given squirts of apple juice paired with a flashing yellow light.

7.   To further refine their search, doctors can place electrodes on the surface of the brain after removing a small portion of the skull.

8.   In experiments at Washington University in St. Louis, Cox had placed electrodes on beating hearts and discovered that in atrial fibrillation, electrical impulses go horribly awry.
