dead brains don't dance

Yesterday I had my last scheduled test: electrodiagnosis of the state of the Jordan neural circuitry in an eyesight style.

I went in on the bus, leaving ramtops at home to man the phones, and was dealt with in the prompt, efficient and friendly way I’ve come to expect from the Eye Hospital; greeted by name by the receptionist in the Electrophysiology department as I arrived, and not even having time to sit down before the tech arrived to deal with me.

Seven electrodes: two by my eyes; two further round my head; three at the back over my visual cortex. Nine tests, all involving a reversing checkerboard pattern on a 22" Iiyama whilst looking in a relaxed but unblinking way at a red square in the middle. Full screen both eyes; full screen right, then left eye; left and right half screen for each eye; full screen small checkerboard for each eye. That was it, and I guess I’ll hear from Dr Ormerod at some point after he gets the results delivered.

I’d be interested in the results myself: they might help clarify how much of what I see through my right eye is down to actual recovery in my optic nerve dielectric, and how much post-processing and interpolation in my brain.
