Canadian COVID-19 travel restrictions imposed in March 2020 greatly reduced SARS-CoV-2 importations, but were insufficient to prevent new sublineages of similar transmissibility from being introduced and replacing early sublineages.

A two-part neural network models reward-based training and provides a unified framework in which to study diverse computations that can be compared to electrophysiological recordings from behaving animals.

Separating behaviorally relevant signals from irrelevant signals reveals that neural signals previously considered to contain little information encode rich information and suggests that linear readout may be performed in motor cortex.

Humans perseverate on previously instructed goals in a novel multigoal reinforcement learning task, and do this to a greater extent for punishment avoidance goals.

De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

Behavioral and computational results show that the perception of our body as our own depends on Bayesian probabilistic reasoning that take into account the variations in sensory uncertainty when integrating visual and somatosensory cues.

Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

For mice, knowing when it is time to feed is dependent on the neurotransmitter dopamine and the D1R receptor of neurons in the dorsal striatum.
