VSS Poster #2 – Did we find the N170 with a homemade machine?

Well, this is Nick’s Do-It-Yourself baby, mostly. It sure looks like we found a larger N170 response to faces (3 subjects, no stats) than to houses, cars or animals (a living/nonliving distinction was the task). We wanted to do an inversion study with the faces to see if the enhanced N170 would be abolished but the equipment broke.

Note though that the equipment found other signatures, such as a pronounced and normal-looking auditory Mismatch Negativity (MMN) – again, only 2 subjects and no stats.

This is promising stuff on the waaaay cheap – we saw a Grass 79D amplifier on Ebay once for $99!
