      Evaluation Summary:

      This manuscript is of broad interest to readers in the field of human vision and its cortical topography as well as behavioral and genetic links. The investigation of the neurobiological basis of visual task performance asymmetries represents an important contribution to our understanding of how visual system architecture shapes perception. The key claims of the manuscript are well supported by the data, and the approaches used are thoughtful and rigorous.

      Evaluation Summary:

      This paper is of interest to psychologists and neuroscientist investigating systems memory consolidation. It describes an experimental protocol that allows precise, quantitative behavioural measurements to assess the development and interactions of item and gist memory traces over extended time periods. The study design and hypotheses are elegant and bring together ideas from several other fields of cognitive psychology (working memory, category learning). However, additional analyses, and in particular, comparison of some simple computational models, are needed before the conclusions are justified.

      Evaluation Summary:

      This paper provides further evidence for hemispheric asymmetry in the cortical control of manual actions based on intracranial (ECoG) recordings in human participants. Specifically, based a linear encoding model, the authors argue that movement encoding is more bilateral in the left hemisphere than the right hemisphere. The paper is well-written and the analyses are largely appropriate for addressing the primary hypothesis, though it would be helpful to detail the variability of electrode placement across individuals (which arises for the clinical intervention being undertaken) and incorporate this variability into the statistical analysis. Given the novelty of this type of human data and the well established question being addressed, this paper will be of interest to both basic and clinical researchers in motor neuroscience.

  4. Separable neural signatures of confidence during perceptual decisions

      Evaluation Summary:

      This paper is of interest to neuroscientists and psychologists working on perceptual decision-making and metacognition. Using a novel task varying the timing of covert decisions, together with sophisticated computational modelling, allowed identifying neural correlates of latent states related to confidence. The conclusions are in line with other papers identifying a dissociation between brain activity supporting performance and confidence, but provide a novel lens through which to understand these differences by focusing on confidence noise. An open issue is how to interpret conclusions about neural correlates of deviations from an ideal-observer model.

  5. Motor planning brings human primary somatosensory cortex into action-specific preparatory states

      Evaluation Summary:

      The authors studied the neural correlates of planning and execution of single finger presses in a 7T fMRI study focusing on primary somatosensory (S1) and motor (M1) cortices. BOLD patterns of activation/deactivation and finger-specific pattern discriminability indicate that M1 and S1 are involved not only during execution, but also during planning of single finger presses. These results contribute to a developing story that the role of primary somatosensory cortex goes beyond pure processing of tactile information and will be of interest for researchers in the field of motor control and of systems neuroscience.

      Evaluation Summary:

      This paper examines the visual-ocular response in participants when exposed to the static magnetic field of a 3T MRI system. Historically, this problem has been approached from a safety perspective. In the present study, the authors ask about the behavioral consequences of this field given that it induces a response in the vestibular system, hypothesized to mimic that of a caloric vestibular stimulation event. As such, one should anticipate a biased vestibulo-ocular reflex in the static field as well as biases in spatial attention. These predictions were confirmed, with the attentional bias manifest in eye movements during a visual search task. This is an important finding because it reveals functional "artifacts" that may arise during fMRI studies, effects that may need to be considered by those conducting research in the MR environment (especially functional studies).
