Human listeners rapidly form robust, long lasting (up to 7 weeks) memories of rarely encountered, featureless sound sequences presented among many similar stimuli.

A proposed model of optimal inference under cognitive costs accounts for human sequential effects, including subtle patterns of attractive and repulsive influence of past observations, in a binary prediction task across a wide range of stimulus conditions.

Hippocampal place cells modulate their firing rate during replay events to reflect the increases, or decreases, in firing rate experienced between contexts during behavior.
Inspired by the sparse, sequential neural activity patterns observed in striatum, a new circuit model implements variable-speed activity, the encoding of multiple sequences, and a tutor/student relationship between cortex and striatum.
Mental codes that track our position within complex, behavioral sequences, have been hard to pin down empirically, but can be identified and traced over time using oscillatory EEG activity.
The consolidation of newly acquired motor skills induces a functional reorganization of sequential information representations within secondary motor cortex, basal ganglia and hippocampus.

Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.
Time-related sequential activities in prefrontal cortex exhibit stable coding over weeks, while representations of other variables are dynamic, suggesting that neural sequences are consisted of unique group of neurons.
Low-dimensional external inputs are sufficient to control the speed of sequential activity, and to transition between persistent activity, in a network of neurons with both temporally symmetric and asymmetric learning.
Time-lapse recording and theoretical analysis of individual cells isolated from the zebrafish segmentation clock reveal that they behave as self-sustained, autonomous oscillators with distinctive noisy dynamics.
