A screw microdrive for adjustable chronic unit recording in monkeys.
نویسندگان
چکیده
A screw microdrive is described that attaches to the grid system used for recording single neurons from brains of awake behaving monkeys. Multiple screwdrives can be mounted on a grid over a single cranial opening. This method allows many electrodes to be implanted chronically in the brain and adjusted as needed to maintain isolation. rights reserved.

Optical imaging combined with targeted electrical recordings, microstimulation, or tracer injections.
To facilitate the combination of optical imaging with various electrode-based techniques, we have designed and produced a skull-mounting "sliding-top cranial window" and a removable "electrode positioner microdrive". These new devices were used to study sensory processing in chronic and acute experiments in the cerebral cortices of cats and monkeys. This assembly allows simultaneous optical ima...

متن کاملA microdrive positioning adapter for chronic single unit recording.
A new micropositioner design for use in chronic, transdural single unit recording studies is presented. The adapter is used to position an electrode microdrive assembly to any desired location within a surgically implanted recording chamber. The adapter uses a radial positioning technique that requires few moving parts. In comparison with the X-Y slide manipulator it replaces, it is more durabl...
متن کاملLarge-scale chronically implantable precision motorized microdrive array for freely behaving animals.
Multiple single-unit recording has become one of the most powerful in vivo electro-physiological techniques for studying neural circuits. The demand has been increasing for small and lightweight chronic recording devices that allow fine adjustments to be made over large numbers of electrodes across multiple brain regions. To achieve this, we developed precision motorized microdrive arrays that ...
متن کاملTelemetric recording of neuronal activity.
A telemetric system is described which allows the wireless registration of extracellular neuronal activity and vocalization-associated skull vibrations in freely moving, socially living squirrel monkeys (Saimiri sciureus). The system consists of a carrier platform with numerous guiding tubes implanted on the skull. Custom-made microdrives are mounted on the platform, allowing the exploration of...
