What this trial measures

  • Neuronal ActivityOne week after recording in OR completed

    Single Neuron firing rate (spikes) measured in spikes per second - total number of isolated neurons, amplitude (in uV of spikes) - by Intan Neurophysiology Recording System

  • Breakage of ElectrodeOne week after recording in OR completed

    Extent of fracture of electrode tip measured in micrometers by a light microscope
