Carter underwent a follow up procedure on June 11. He has wires inserted into the left side of his head, routed through his neck and connected to a pacemaker that rests under his left armpit. He continues to see Pouratian and his medical team for follow-up visits to fine-tune the programming of the electrodes with attention to frequency, strength and length of the electrical pulses in his brain.
"If you do the math, there are hundreds of thousands of iterations of how you can stimulate someone’s brain, even with a precise localization, and we want to make that as perfect as possible....That’s the phase we’re in with Brad at this point," said Pouratian. "We’re really only at the beginning of his programming, starting to see some improvement, and with time we will see more and more improvement as we get the programming better and as his brain adapts to that stimulation."
According to Pouratian, 100,000 such surgeries have been performed worldwide. There are an estimated 180,000 people in the United States who could be candidates for this treatment. This procedure, Pouratian emphasized, is not a cure for any of the conditions it treats. Each patient responds differently to treatment, he said.
Carter is just happy that he's able to play the guitar better now than before the surgery. He's looking forward to going into the studio. "There’s nothing like losing a skill that you were really good at to make you want to have that skill back," Carter said. "I can’t wait to be creative again and I can’t wait to play guitar again. I’m very excited to record an album as this gets better."
