Hormonal Control of Symbiotic Nitrogen Fixation. Ethylene (ET) represses calcium spiking induced upon recognition of a compatible Nod factor (1). Rhizobial infection is countered by the hormones ET, jasmonic acid (JA), and gibberellic acid (GA).

We show that it successfully captures trial-to-trial fluctuations in the weighting of sensory stimuli, bias, and task-irrelevant covariates such as choice and stimulus history. This analysis reveals dramatic differences in learning across mice and rapid adaptation to changes in task statistics.

2021年10月18日 · Roy et al. present a method for inferring the time course of behavioral strategies in sensory decision-making tasks, which they use to analyze how behavior evolves during training in rats, mice, and humans. Decision-making strategies evolve during training and can continue to vary even in well-trained animals.

2020年1月9日 · In this issue of the JCI, Roy et al. show that Aβ complexed with nucleic acids triggers an antiviral type I interferon response in neuroglia, resulting in complement-mediated synapse elimination in AD models.

2020年1月13日 · Expert opinion and consensus approaches (Roy et al., 2014, 2019) were used to develop a ranked list of potentially invasive non-native species, currently absent, that are considered likely to arrive, establish and have an impact on native biodiversity and ecosystems over the next decade. The exercise also aimed to identify high-risk pathways to ...

Our model consists of a dynamic logistic regression model, parametrized by a set of time-varying weights that express dependence on sensory stimuli as well as task-irrelevant covariates, such as stimulus, choice, and answer history.

Our results demonstrate multiple lines of evidence that these fossil microbodies are indeed melanosomes: the geometry of decay-associated microbes differs significantly from fossil microbodies; fossil microbodies are very strongly localized to in vivo melanized tissues and are absent in tissues typically unmelanized in vivo, in all fossils exami...
