Topic: low-dimensional neural manifold

In the mouse visual cortex, neural representations of stimuli fluctuate across repetitions (Schölvinck et al. 2015, Deitch et al. 2021). The single-trial dynamics, often termed as representational drift, were also found in other cortical structures (Rokni et al. 2007, Low et al. 2021, Schoonover et al. 2021). However, most of these studies focused on slow drift over days. Here, we demonstrated that representational drift occurs at a fast timescale of several minutes and is prevalent regardless of stimulus type and independent of behavioral state. Within sessions of the same day, repeats of the
