Abstract:
Focal cooling is considered a potential solution to stop or control epileptic activity. However, despite the available proof of concept studies, such approach requires further validation before being used in humans. One hindering factor is the lack of suitable devices to enable large-scale validation of such methodology. This paper presents a wireless thermal neuromodulator that can wirelessly record the rat’s brain electrical activity and temperature. At the same time, the temperature is reduced without the need to use cumbersome liquid pipes. The proposed device has two modules: one headstage with a cooler and sensors, and one backpack with acquisition electronics and wireless communication capability. It is possible to record the brain temperature, the EEG at 16 kbps, and to control the cooler’s temperature, with an autonomy of 1 day.
