  • 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.

  • The mechanisms of recognition and response to emotional stimuli are not fully understood. Here, the authors reveal tuning to semantic and emotional image features within occipital temporal cortex that efficiently encodes information suited to guiding behavior.

  • The neural dynamics underlying speech comprehension are not well understood. Here, the authors show that phonemic-to-lexical processing is localized to a large region of the temporal cortex, and that segmentation of the speech stream occurs mostly at the level of diphones.

  • Recent functional magnetic resonance imaging (fMRI) studies have shown that it is possible to deduce simple features in the visual scene or to which category it belongs. A decoding method based on quantitative receptive field models that characterize the relationship between visual stimuli and fMRI activity in early visual areas has now been developed. These models make it possible to identify, out of a large set of completely novel complex images, which specific image was seen by an observer.

  • Previous studies have attempted to decode functional imaging data to infer the perceptual state of an observer, but the level of detail has been limited. A new decoding study reconstructs accurate pictures of what an observer has seen.

  • The authors use functional magnetic resonance imaging to measure how the semantic representation changes when searching for different object categories in natural movies. They find tuning shifts that expand the representation of the attended category and of semantically related, but unattended, categories, and compress the representation of categories semantically dissimilar to the target.

  • In this Opinion article, Hunt and Hayden highlight that many of the models for reward-based choice are based on distinct component processes that occur in series and are functionally localized. They argue that, instead, such choice emerges from repeated computations that are undertaken in many brain areas.
