Our Second Generation Bussey-Saksida Rodent Touch Screen Chambers have been adapted for easy integration with electrophysiology recording. All electronic components have been adjusted to reduce EMC. The sound attenuating chamber is a Faraday cage to prevent outside noise from the surrounding building entering the chamber. The touchscreen itself is shielded to reduce noise emission. In addition, there is a slotted lid to accommodate tethers and reward troughs that allow for head-stages. A sliding top shelf on which commutator can be mounted and TTL inputs and outputs to communicate with the electrophysiology recording.
As can be seen in the graphs below, spikes in noise are reduced with the Ephys touch screen chamber electronic components.
The graphs below show the typical outside electromagnetic radiation and how it is blocked by the E-Sound attenuating chamber
The graphs below show how shielding the touch screens smooths out spikes in emissions.
The floor is coated with a non-conductive coating to prevent artifacts being created from the oscillating ground contact created by the animal's normal motion.
Chambers include enlarged reward trough entries to accommodate many head-stages. For mice an alternative reward trough is available where the liquid reward tray protrudes into the chamber, so the mouse does not have to place their head into the trough.
Chamber lids have been updated to include slotted lids for the touchscreen chambers to accommodate head-stages, commutators and tethers.
We have raised the height of the sound attenuating chambers to allow longer tethers, as the longer the tether the more flexible it becomes, reducing the pull on the animal's head and consequential fatigue.
Commutators can be mounted on a pull-out top shelf preventing the need for drilling into the sound attenuating chamber. This allows the commutator to be slid out with the rodent chamber, for easy access and to prevent the tether needing extra length when the rodent touch screen chamber is pulled out on its sliding shelf.
Cable access points are available for 3rd party systems.
Custom sized sound cubicles and builds can be quoted to individual requirements.
TTL inputs and outputs are available to enable ABET Cognition software to communicate with other third-party software such as electrophysiology recording software.
Precision food dispenser with dispensing wheel that accommodates 14mg pellets.
ABET Core Intelli-interface is a smart interface which controls all aspects of your chambers including touchscreen and computer-generated audio.
From writing schedules to analyzing data, ABET Cognition gives you the powerful and flexible tools necessary to control a network of touch screen chamber systems.
Second Generation Bussey Chamber developed for mice with Intelli-interface supports up to 20 chambers on one PC. On the strength of 10 years of feedback and development, the system is even more flexible and with more features.
The rate of flow for the Precision Liquid Feed Pump is been calibrated to give precise delivery of liquids at delivery rates suitable for rewarding mouse, rat, and primate.
