Data for parametrizing alternating current stimulation for neuromodulation

Data collected using a 4x4 multielectrode array (Microprobes) in propofol anesthetized rats receiving subcutaneous alternating current stimulation. Recording electrodes had platinum iridium shanks with a tip width of 125μm, an impedance of 0.4 MOhm, and were spaced 0.5mm apart in the lateral plane. An additional shank with 10 kOhm impedance served as a reference. Electrodes were inserted ~300μm into the craniotomy exposed sensorimotor cortex (L2/3). Data was acquired with a sampling rate of 24 kHz (Tucker-Davis Technologies). Stimulation electrodes were adhered directly to the skull, medial and lateral the cranial window.
