Comparative study of the synfire chain and ring attractor model for timing in the premotor nucleus in male Zebra Finches

Year: 2023

Type: conference-paper

Abstract: Timing is crucial for the generation of a wide range of sensorimotor tasks.However, the underlying mechanisms remain unclear.In the order of milliseconds, premotor nucleus HV C (proper name) in male zebra finches is an outstanding model in studying the sequential neuronal activity encoding action timing.Current computational models of HV C rely on the synfire chains, which are not robust to noise and function for a narrow range of weights.An alternative with robust functional properties [11][5] are attractors.Here, we compare the two models and show that not only the ring attractor is more robust, but can also reproduce the brief activity bursts of HV C neurons.
