Caption
Two retractable levers are located on the front panel on either side of a receptacle for delivery of food pellets. Approximately 0.3 ml of each taste sample is dispensed in each well of a standard 96-well plate placed on top of an x-y motion table beneath the floor of the chamber. Rats are trained to first lick the contents of a single well, which can be accessed through a small hole in the floor, and then press the lever that is associated with the taste of the sample. The number of licks is recorded by a laser beam projected across the top of the well to give a quantitative measure of palatability, and the percentage of lever presses quantifies taste quality.
