Serotonin 5-HT1A receptor binding and self-transcendence in healthy control subjects—a replication study using Bayesian hypothesis testing

Editor rating: 8 / 10

Kevin Black –– The authors do real science here, following up on an initial finding from a pilot study and reporting the outcome appropriately. That may sound obvious, but in the real world of research these days it is a delightful breath of fresh hair.
Saccades and handedness interact to affect scene memory

Editor rating: 6 / 10

Anthony Barnhart –– This paper is one of the first to explore the limits of Saccade-Induced Retrieval Enhancement and its relationship with multiple memory systems.
Clustering of fMRI data: the elusive optimal number of clusters

Editor rating: 9 / 10

Jafri Abdullah –– the number of clusters have always been debatable,
Does Twitter language reliably predict heart disease? A commentary on Eichstaedt et al. (2015a)

Editor rating: 8 / 10

Tjeerd Boonstra –– The article re-examines the results of an influential paper and challenges the idea that social media data analysed on a county-level may provide a reliable predictor of health outcomes. The authors raise several questions on the reliability of data and study design that need to be addressed for this field going forward.
Parvalbumin expression and gamma oscillation occurrence increase over time in a neurodevelopmental model of NMDA receptor dysfunction

Editor rating: 6 / 10

Maria Concetta Geloso –– The article provides new experimental tools to explore alterations of neurotransmission which are frequently involved in neurodevelopmental and neuropsychiatric diseases.
Explanation of observational data engenders a causal belief about smoking and cancer

Section Editor rating: 7 / 10

Claire Fletcher-Flinn –– I agree with the reviewers comments re causality.
A short, robust brain activation control task optimised for pharmacological fMRI studies

Editor rating: 6 / 10

Kevin Black –– The authors provide a simple set of tasks that, collectively, activate a large fraction of brain regions in BOLD fMRI. They further provide the code and their analysis results, to facilitate adoption of these tasks.
Episodix: a serious game to detect cognitive impairment in senior adults. A psychometric study

Section Editor rating: 7 / 10

Stephen Macknik –– This advance will potentially have significant impact in diagnosis and therapeutic tracking for mild cognitive impairment.
The influence of residual force enhancement on spinal and supraspinal excitability

Editor rating: 7 / 10

Tjeerd Boonstra –– The paper further enhances our understanding of muscle mechanics and muscular contraction
A computer-based avatar task designed to assess behavioral inhibition extends to behavioral avoidance but not cognitive avoidance

Editor rating: 7 / 10

Jafri Abdullah –– Methodology looks interesting and reproducible

Our human-data interaction paper studying the question of whether explanation implies causation for consumers of data analysis is out today. Randomized, replicated trial, but just the first look at an important question! https://t.co/4YVzxWL51p.

Hey all - new paper out today! This one was led by the inimitable @brainsandbanter, and also featured the talents of @Lysia9. We developed a new brief fMRI paradigm that we hope will be useful for others. Paper URL: https://t.co/juRMaWjOg7
