The OP's point about damage still holds. After implanting the chronic arrays you have to wait about 3 weeks before recording (the area is silent). It is assumed that the responses are normal after that - and it seems so. But we have a lot of results from arrays that have no counterpart from single electrode recordings so we really don't know.
You are basically jamming a pincushion into the cortex. Trauma is inevitable. The denser the array the more the damage (the more mass you are jamming into cortex). You most likely have a perturbed cortex that has recovered from damage.
Is this the same as original intact cortex?
- simonster 12y agoYes, the typical caveats of putting things in the brain still apply. But I'm expecting that the increased density in these arrays will come mostly from putting multiple contacts on each shank rather than putting the shanks closer together, which may not produce any more damage than an ordinary Blackrock array.
