| <b>Typical Protocol</b>
| |
|
| |
| <p><b>Monday - electrode implantation</b><br>
| |
| 1. Check batteries on BAK stimulator, and change if reading lower than 115V (reads ~ 135V with brand new complement of batteries). Be very careful not to yank internal wires.<br>
| |
| 2. Check batteries on patient interface, and change if reading lower than 18V (reads ~ 27V with brand new complement of batteries).<br>
| |
| 3. Set up cabling for ITC to record from 16 channels (unplug channel 1 to test stimulation circuit). <br>
| |
| 4. Using the oscilloscope, check TTL pulse for gate and monitor out signal with stimulation circuit online.<br>
| |
| 5. Pick up CT scan from radiology library (signed HIPAA release required) after surgery (~11AM).<br>
| |
| 6. Merge 2nd structural MRI with CT on Stealth.<br>
| |
| 7. Merge 2nd structural MRI with CT on AFNI and view with functional activation on cortical surface to select candidate electrodes.<br>
| |
| 8. Have Lisa or Rodney jumper the candidate electrodes from the jackbox to our amplifiers.<br>
| |
| 9. Double check that the jumpered electrodes are the ones we want.<br>
| |
| 10. Make sure cart, display, and eye tracker are room-ready.<br>
| |
| 11. Have tape measure, several surgical grounding pads available.<br>
| |
|
| |
|
| |
| <p><b>Tuesday or Wednesday - experiments</b><br>
| |
| 1. Have Lisa or Rodney place scalp reference and ground electrodes. Check for good signals on all 16 channels.<br>
| |
| 2. Turn on KNOT.<br>
