Short- vs long-range white matter fibers

Myelination of axons enables faster signal propagation in the brain, but also requires more energy and space. Philip Ruthig, David Edler v.d. Planitz, Markus Morawski and colleagues reveal key differences between short- and long-range white matter fibers and show how these variations affect overall neural communication and processing efficiency.

Attractive serial dependence arises during decision-making

Our memory of a stimulus can be biased toward or away from previous stimuli, but when this bias arises is unclear. Jiangang Shan and coworkers show that attractive serial dependence emerges during decision-making, supported by neural evidence of late-stage attractive biases, while repulsive biases originate during early sensory encoding.

Early spillover events determine viral persistence

Virus spillover into new host species can lead to outcomes ranging from dead-end infections to sustained epidemics. Clara Shaw and David Kennedy use a nematode-virus model to show that early spillover traits, especially infection prevalence and shedding, are important predictors of viral persistence.

How are memories retrieved?

Involuntary memory retrieval is a common phenomenon in autobiographical memory and a symptom of posttraumatic stress disorder. In an electroencephalography study, Malte Kobelt, Gerd Waldhauser, Nikolai Axmacher and colleagues elucidate the neural mechanism of involuntary memory, revealing that involuntary and voluntary memories rely on distinct neural processes.

Expansion of immature neurons in the primate amygdala

Immature neurons have been identified in the adult amygdala of some mammalian species, but their prevalence has not been systematically examined. Marco Ghibaudi, Luca Bonfanti and co-workers characterize amygdalar immature neurons in eight mammalian species, revealing phylogenetic variation and a high prevalence in primates.

Plants mount cheaper defenses first

Plants encounter natural threats of varying intensity and respond by activating multiple defense traits. This study of six defense traits in Ambrosia artemisiifolia, by Jinlong Wan, Wei Huang and co-authors, reveals that when attacked by insect herbivores, less costly traits are induced first, while more costly traits are activated only after higher damage thresholds. Don't miss the accompanying Primer by Ethan Bass.

Transferring skills from one hand to the other...

How does the brain transfer motor skills between hands? Ali Rezaei, Jason Gallivan and colleagues reveal that transfer relies on re-expressing the neural patterns established during initial learning in distributed higher-order brain areas, offering new insights into learning generalization. Also see the Primer by Hiroshi Imamizu and Toshiyuki Kondo.

Perspective

Too few pathogens

Why are there so few pathogens, and what determines their emergence? John Drake argues in this Perspective that ecological and evolutionary forces (host availability, geographic exposure and microbial innovation) will shape future human diseases.

Essay

The ghost of infections past

This Essay argues that experimental disease ecology can offer powerful tools and approaches to better understand and predict the epidemiological consequences of variable infection history.

Perspective

Science and trust

What happens when the greatest strengths of science – openness, humility, self-criticism and self-correction – are exploited for political gain? Brian Nosek calls for scientists to affirm the genuine application of those strengths as the source of its trustworthiness.
