MRI COMPATIBLE electrophysiology Introducing MagRes, our MRI Compatible Headstage. MagRes is the world's smallest, lightest, and first MRI-compatible headstage that fits in the MRI bore with the animal.

MagRes – Small, light and MRI Compatible

Blackrock’s new MagRes, MRI Compatible Headstage, is a lightweight, 16-channel, single-unit, analog recording headstage for small animals that fits in the bore with the animal. It buffers and then transmits neural signals through a coaxial ribbon cable to a CerePlex A or Front-end Amplifier (FEA). The data is then acquired by either a CerePlex Direct or a Neural Signal Processor (NSP). The headstage will allow small animal researchers to directly correlate neural activity with hemodynamic changes detected on MRI for awake and responsive subjects.
