| Outline of Final Research Achievements |
Appropriate timing and enough precision of speech production is essential for our vocal communication to represent our intention. In the present research, we aimed to establish an animal model which produces appropriate timing with enough precision to investigate the brain mechanism of timing production for quick actions such as speech, by using a conventional laboratory animal, guinea pig. We succeeded to condition guinea pigs to discriminate at most three timing cues and to switch timing of response for each cue. Guinea pigs produced timing with ±5% error (at minimum) for 0.3 sec timing, which is comparable to real vocal communication of guinea pig. Taken together, the animal model was successfully established and now we have a basis to study how brain produces timing to represent our intention with invasive techniques.
