  • Title: [Transducer of the coordinates of a biological object for the Thermogradient device].
    Author: Bunegin VV, Isabekova SB.
    Journal: Nauchnye Doki Vyss Shkoly Biol Nauki; 1983; (8):103-7. PubMed ID: 6626617.
    Abstract:
    A device designed to determine the position of a biological object within the experimental field used to investigate behavioral reactions has been described. By means of light sources focusing the photodetector objective lens the square experimental field is divided into 9 equal sections. The movement of an animal in question from one section of the experimental field to another excites electric signals at the output of the corresponding photodetectors. These signals are processed and stored in the location unit made of integrated circuits. Further data processing for their convey to the pen-and-ink recorder is accomplished in the write pulse forming unite which is also made of microcircuits and discontinuous semiconductors. The device permits to document all the movement parameters of animals within the experimental field throughout the experiment.
