About the cover

It is thought that the meanings of words and language are represented in a semantic system distributed across much of the cerebral cortex. However, little is known about the detailed functional and anatomical organization of this network. Alex Huth, Jack Gallant and colleagues set out to map the functional representations of semantic meaning in the human brain using voxel-based modelling of functional magnetic resonance imaging (fMRI) recordings made while subjects listened to natural narrative speech. They find that each semantic concept is represented in multiple semantic areas, and each semantic area represents multiple semantic concepts. The recovered semantic maps are largely consistent across subjects, however, providing the basis for a semantic atlas that can be used for future studies of language processing. An interactive version of the atlas can be explored at http://gallantlab.org/huth2016. The cover shows the cortical surface of one subject, overlaid with words predicted to cause particularly strong responses at the corresponding cortical location. Word colours indicate semantic categories: for example, green words are mostly visual and tactile concepts, and red words are mostly social concepts. White lines show the outlines of previously known regions of interest. Cover: Alex Huth

  • Natural speech reveals the semantic maps that tile human cerebral cortex

    • Jack L. Gallant

    It has been proposed that language meaning is represented throughout the cerebral cortex in a distributed ‘semantic system’, but little is known about the details of this network; here, voxel-wise modelling of functional MRI data collected while subjects listened to natural stories is used to create a detailed atlas that maps representations of word meaning in the human brain.

    Plankton communities in the top 150 m of the nutrient-depleted, oligotrophic global ocean that are most associated with carbon export include unexpected taxa, such as Radiolaria, alveolate parasites, and Synechococcus and their phages, and point towards potential functional markers predicting a significant fraction of the variability in carbon export in these regions.

  • Dynamics from noisy data with extreme timing uncertainty

    A data-analytical approach that can extract the history and dynamics of complex systems from noisy snapshots on timescales much shorter than the uncertainty with which the data were recorded is described; the approach is demonstrated by extracting the dynamics on the few-femtosecond timescale from experimental data recorded with 300-femtosecond timing uncertainty.

    The simplest form of the Hubbard model includes only on-site interactions, but by placing an optical lattice filled with ultracold rubidium atoms into an optical cavity the Hubbard model is implemented with competing long- and short-range interactions; four phases emerge, namely, a superfluid phase, a Mott insulating phase, a supersolid phase and a charge density wave phase.

    A modification to the classic Diels–Alder [4 + 2] cycloaddition reaction, termed the pentadehydro-Diels–Alder reaction, is reported; this reaction generates a highly reactive intermediate, an α,3-dehydrotoluene, that can be captured using various trapping agents to produce structurally diverse products.

    Aircraft measurements, laboratory photolysis experiments and modelling calculations reveal a mechanism for the recycling of nitric acid into nitrogen oxides; this enables observations to be reconciled with model studies, and suggests that particulate nitrate photolysis could be a substantial tropospheric nitrogen oxide source.

  • Bubble accumulation and its role in the evolution of magma reservoirs in the upper crust

    Here, the authors model the fluid dynamics that controls the transport of the magmatic volatile phase (MVP) in crystal-rich and crystal-poor magmas; they find that the MVP tends to migrate efficiently in crystal-rich parts of a magma reservoir but to accumulate in crystal-poor parts—possibly explaining why crystal-poor silicic magmas are particularly prone to erupting.
