Spike Frequency Adaptation Implements Anticipative Tracking in Continuous Attractor Neural Networks

no code implementations • NeurIPS 2014 • Yuanyuan Mi, C. C. Alan Fung, K. Y. Michael Wong, Si Wu

To extract motion information, the brain needs to compensate for time delays that are ubiquitous in neural signal transmission and processing.

A Synaptical Story of Persistent Activity with Graded Lifetime in a Neural System

no code implementations • NeurIPS 2014 • Yuanyuan Mi, Luozheng Li, Dahui Wang, Si Wu

Here, in contrast to the view of attractor, we consider that the stimulus information is encoded in a marginally unstable state of the network which decays very slowly and exhibits persistent firing for a prolonged duration.
