A scalable parallel injector array has a support structure for holding injector tubes in a spatial pattern in order to enable delivery of fluidic materials simultaneously to a group of specific target areas in the brain or a body part. Each injector is individually connectible at one end to a displacement-controlled pump and is designed at the other end to be inserted into the brain or body part. The injector tubes are connected to the pump by fluid-filled tubing. The spatial pattern is patient- and/or application-customizable, and the length of the injector tubes is customizable in order to more precisely reach individual target areas. A clamping device may be used to attach the injector array to a stereotaxic arm or other support structure. The action of the pump permits controlled simultaneous delivery of the fluidic materials to the target areas.
