title: A grid system and a microsyringe for single cell recording.
abstract: The designs of two instruments are presented which have proven to be useful in single cell and chemical injection studies performed in awake monkeys. The first is a plastic grid that acts as a guide to produce parallel penetrations with either a microelectrode or microsyringe. The second is a syringe for injecting microliter quantities of a solution that also allows recording of neuronal activity.
