| Outline of Final Research Achievements |
We discovered that mormyrid weakly electric fish, B. brachyistius, occasionally pause discharging for approximately one second during electric communication. Such pauses facilitated the receiver’s behavioral response to the signals following pauses. The duration of pauses corresponded to the time course of recovery from a short-term synaptic depression in the midbrain nucleus ELp, which is necessary for analyzing temporal structure of mormyrid electric communication. Humans also pause during conversation and pausing is a key factor in making a speech impressive. Thus, the present study suggest the first neuronal mechanism underlying psycholinguistic effects of pausing.
