Eeg device
While existing wireless EEG devices allow greater freedom of movement, they are still relatively heavy for mice to carry (>4g) and have limited battery life.

Traditional tethered EEG devices significantly restrict the animal’s movement and limit the environments mice can be tested in.

This project will develop a prototype of a wireless 16-32 channel recording system that can acquire and transmit data for a minimum of 24 hours, can be replaced or recharged with minimum discomfort for the animal and is small enough to be carried by a mouse without affecting its behaviour or welfare.įull details about this CRACK IT Challenge can be found on the CRACK IT website.ĮEG recordings are typically conducted in mice to understand neural activity and how it relates to specific behaviours or cognitive tasks, which is relevant for understanding brain disorders such as Alzheimer’s disease. Added to this, they achieve their size by compromising at least one of the electrical specifications, which limits the experimental output. Although a small number of wireless systems have been developed they are still too big for a mouse to carry without effect. This has an outcome not just on the welfare of the animal, but also on the results and conclusions of the experiment.

very small amplitude, relatively high bandwidth and corrupted by other signals), the only neural recording systems that can meet all the required specifications are brain tethered systems that severely limit the mobility and condition the behaviour of the animal. Unfortunately due to the electrical characteristics of the signals that need to be measured (i.e. Research into new drugs targeting neurological conditions often requires high resolution electrophysiological recordings of mice brain activity.
