Measuring Single Neuron Activity in the Brain

"The SUNAN study is a basic science study involving a procedure to record single-unit neurophysiological activity with human participants who are already undergoing a transcranial neurosurgical procedure on the brain.~As part of the surgery, a region of cerebral cortex on the convexity of the brain will be:~* Resected e.g., as removal of part of a tumour or epilepsy focused. Or~* Transgressed as part of the surgical approach to reach a deeper target e.g., resection of a deep tumour or cavernoma.~Or~• Transgressed by the passage of a surgical implant e.g., a ventriculoperitoneal shunt catheter or deep brain stimulation electrode.~Within this region of the brain that is going to be resected or transgressed, the research team will undertake a single-unit resolution neurophysiological recording (NR) using a digital neural probe (Neuropixels) for a maximum of 15 minutes."
