Task-specific Approach in Customized Design of EEG System for Small Laboratory Animals

Electroencephalography (EEG) of small animal models of brain disorders is the powerful method of neurophysiology that requires efficient, low cost and flexible instrumentation. Most of the commercially available EEG systems for small animals are not flexible enough and do not allow for task-specific modifications, while custom systems developed for a specific task are typically hard to be reproduced because of its specific design.We propose a modular EEG platform with Bluetooth low energy wireless interface that features both implantable and tethered use and allows for easy task-specific adaptation. To illustrate the proposed designapproach, we present a low-cost autonomous instrument for photobiomodulation of mouse brain during deep sleep.
