Dowling Lab: Projected images of drifting gratings are used to drive the visual optokinetic response of larval zebrafish. The response of multiple fish (6-12) can be recorded and analyzed in real time.
Dowling Lab: Software used to generate visual stimulus, record and analyze eye movements.
Dowling Lab: Software running off-line provides an automatic and precise measurement of eye position, temporal registered to the visual stimulus.
Dowling Lab: Equipment designed to simultaneous monitor the swimming behavior of up to 180 fish in response to varying illumination conditions.
Olveczky Lab: Working with Olveczky lab members, custom isolation chambers were designed and constructed to segregate conditioning cages. Water ports can be seen along the back of the chrome rack.
Olveczky Lab: By mounting a tiny microphone on the head of a zebra finch, it is possible to minimize variations in song recordings that arise from changes in the position and orientation of the bird. A miniature speaker directly driving the bird’s auditory system can alter what the animal hears without affecting acoustic recordings.
Schier Lab: The chamber shown allows machine vision software to provide an addressable, controlled, mild, electrical stimulus to each of 96 wells containing a larval zebra fish. By tickling the fish in this manner, the Schier lab can explore the effects of altered sleep patterns on behavior.
Uchida Lab: Two of many computer-controlled 16 channel olfactometers capable of producing precise mixtures of odors and variable concentrations. They are part of a larger system of hardware and software produce by the Neuroengineering facility designed to measure the behavior of rodents in a nose-poke olfactory discrimination task.
Uchida Lab: A rodent behavioral chamber designed to measure the subject’s value of immediate and delayed reward. Variable numbers of food pellets can be delivered to each food window, access to which is under temporal control. Retractable levers report the animal’s response.
Zhang Lab: Equipment for measuring the turning behavior of C. elegans in the presence of odorants. The leftmost hose maintains stage temperature while the right hose delivers odor laden air to a chamber that houses the worm suspended in a hanging water droplet. Responses are recorded by the camera underneath.
Zhang Lab: Worm tracking “microscope”. Machine vision software maintains the camera above a target-worm within a 14” x 14” arena. Other custom software analyzes body motion, speed, turn probability, etc.
Buckner Lab/MRI facility: Patch panel maintains shielding while allowing cabling to reach into the scan area.
Samuel Lab: An actual experiment tracking the response of multiple worms in the presence of a gradient. Apparent surface imperfections are simply beads of condensed water that result from the humidity of the chamber.
