Abstract: | A simple electronic device to detect location or to track locomotion of small animals is described. The device is based on anantenna effect—it responds to a change in capacitance as the body of the animal passes between an antenna and one of a series of contact plates. A digital address system is incorporated that is capable of electronically polling the contact plates according to instructions from a data-acquisition system (DAS). Any DAS capable of generating an address of two bits or more and of reading a one-bit data line may be employed. The device is ideal for mazes or other apparatus in which the exclusion of stereotypical behaviors is desired. |
