Ashlee Vance walks through how Neuralink builds anatomical models for surgical training. They pour silicone tinted to match skin tone into patient-specific scalp molds, let it cure for four hours, then demolding creates a custom replica. The scalp is the first piece of a full brain proxy used for mock surgery.
Today we're gonna build a full proxy. The items we're gonna make are the scalp, the head, the skull cap, the veins, the brain itself, and then we're gonna put it all together and run a fake surgery on it. So step 1, we'd start with the scalp. We have these custom scalp molds that are patient-specific. We're gonna mix some silicone together, add some dye to mimic the skin tone, and then pour it into the mold. 4 hours later, we'll demold the silicone and we'll have a patient-specific scalp.
