Abstract
Comparison between neuronal and behavioral activities in response to sign stimuli requires recordings from single cells during the animal’s behavior. For studies of successive action patterns, such as habituation of orienting in response to repetitively presented prey, wireless transmission of electrical signals is required. In this paper, we present a miniature three-function system developed for toads that allows us, by means of a telemetric procedure, to record single neurons from the brain and to stimulate and to subsequently lesion the recording site through the recording electrode. Spikes are transmitted by using frequency modulation for distances up to 10 m. Electrical brain stimulation through the recording electrode is performed with the aid of an inductively powered circuit which is combined with the transmitter (mass of the system 2.38 g). Biphasic current pulses can be applied. Pulse frequency and duration are wireless remotely controlled.
The paper presented here in an edited form was prepared in 1985. Parts were published by C. Pinkwart and the late H.-W. Borchers in the Journal of Neuroscience Methods 20: 341-352 (1987). The Editors.
