Computer assisted neuron searching.
A microprocessor controlled driver for the Kopf hydraulic microdrive is described. Neuron searching parameters can be specified during an experiment to facilitate the search for active neurons. These parameters include: period between movements, numbers of microns of electrode movement/advance, depth of penetration, automatic cessation of advancement when activity is encountered, and slow or rapid rates of movement. In addition, analog voltage outputs are available that are proportional to impulse frequency and to total impulse count.
