Blackrock Microsystems MagRes MRI-compatible headstage

The MagRes from Blackrock Microsystems is a single-unit, analog recording, MRI-compatible headstage available for small animal and non-human primate researchers to directly correlate neural activity with haemodynamic changes detected on MRI for awake and responsive subjects.

The device has been successfully tested for heating, migration and image artefact in the MRI environment up to 16.4 tesla and can record single unit spikes and wide band signals while in an MRI during scan without distorting image (no imaging artefact). Lightweight and small (16-ch is 0.5 g, 8 x 19 x 2 mm; 32-ch is <1 g, 16 x 19 x 2 mm), the product has a small form factor allowing the animal to comfortably wear the analog headstage while in the MRI during operation.

The unit provides an isolated low-impedance output that enables signal integrity, minimises noise pickup by cables and offers maximum common-mode noise rejection when using the Cereplex A. The headstage is compatible with MicroFlex Array, Cereplex Direct, CereStim and the Cerebus, which are all available from Blackrock Microsystems.
