Summary 1The role of phenotypic plasticity in evolution has historically been a contentious issue because of debate over whether plasticity shields genotypes from selection or generates novel opportunities for selection to act.

Top-down inputs enhance orientation selectivity in neurons of the primary visual cortex during perceptual learning. [PDF]
Perceptual learning has been used to probe the mechanisms of cortical plasticity in the adult brain. Feedback projections are ubiquitous in the cortex, but little is known about their role in cortical plasticity.

Sensory plasticity in a socially plastic bee [PDF]
AbstractThe social Hymenoptera have contributed much to our understanding of the evolution of sensory systems. Attention has focussed chiefly on how sociality and sensory systems have evolved together. In the Hymenoptera, the antennal sensilla are important for optimizing the perception of olfactory social information.

Effect of competitive cues on reproductive morphology and behavioral plasticity in male fruitflies [PDF]
Phenotypic plasticity will be favored whenever there are significant fitness benefits of responding to environmental variation. The extent and nature of the plasticity that evolves depends on the rate of environmental fluctuations and the capacity to ...

Plasticity, plasticity, plasticity…and the rigid problem of sex [PDF]
Why is popular understanding of female-male differences still based on rigid models of development, even though contemporary developmental sciences emphasize plasticity? Is it because the science of sex differences still works from the same rigid models?

Diversity, Mechanisms, and Significance of Macrophage Plasticity.
Macrophages are a diverse set of cells present in all body compartments. This diversity is imprinted by their ontogenetic origin (embryonal versus adult bone marrow-derived cells); the organ context; the activation or deactivation of various signals in ...

Lineage plasticity in prostate cancer depends on JAK/STAT inflammatory signaling
Drug resistance in cancer is often linked to changes in tumor cell state or lineage, but the molecular mechanisms driving this plasticity remain unclear. Using murine organoid and genetically engineered mouse models, we investigated the causes of lineage

Pancreas homeostasis is based on replication of differentiated cells in order to maintain proper organ size and function under changing physiological demand. Recent studies suggest that acinar cells, the most abundant cell type in the pancreas, are facultative progenitors capable of reverting to embryonic-like multipotent progenitor cells under injury ...

Tool use induces complex and flexible plasticity of human body representations [PDF]
Plasticity of body representation fundamentally underpins human tool use. Recent studies have demonstrated remarkably complex plasticity of body representation in humans, showing that such plasticity: (1) occurs flexibly across multiple time-scales, and (

Macrophage plasticity, polarization, and function in health and disease
Macrophages are heterogeneous and their phenotype and functions are regulated by the surrounding micro‐environment. Macrophages commonly exist in two distinct subsets: 1) Classically activated or M1 macrophages, which are pro‐inflammatory and polarized ...
