The perils of global signal regression for group comparisons: a case study of Autism Spectrum Disorders.
Published in Frontiers in human neuroscience
We have previously argued from a theoretical basis that the standard practice of regression of the Global Signal from the fMRI time series in functional connectivity studies is ill advised, particularly when comparing groups of participants. Here, we demonstrate in resting-state data from participants with an Autism Spectrum Disorder and matched co...
Control beliefs can predict the ability to up-regulate sensorimotor rhythm during neurofeedback training.
Published in Frontiers in human neuroscience
Technological progress in computer science and neuroimaging has resulted in many approaches that aim to detect brain states and translate them to an external output. Studies from the field of brain-computer interfaces (BCI) and neurofeedback (NF) have validated the coupling between brain signals and computer devices; however a cognitive model of th...
Single trial decoding of belief decision making from EEG and fMRI data using independent components features.
...Published in Frontiers in human neuroscience
The complex task of assessing the veracity of a statement is thought to activate uniquely distributed brain regions based on whether a subject believes or disbelieves a given assertion. In the current work, we present parallel machine learning methods for predicting a subject's decision response to a given propositional statement based on independe...
Oxytocin and socioemotional aging: Current knowledge and future trends.
Published in Frontiers in human neuroscience
The oxytocin (OT) system is involved in various aspects of social cognition and prosocial behavior. Specifically, OT has been examined in the context of social memory, emotion recognition, cooperation, trust, empathy, and bonding, and-though evidence is somewhat mixed-intranasal OT appears to benefit aspects of socioemotional functioning. However, ...
Mindfulness starts with the body: somatosensory attention and top-down modulation of cortical alpha rhythms in mindfulne...
Published in Frontiers in human neuroscience
Using a common set of mindfulness exercises, mindfulness based stress reduction (MBSR) and mindfulness based cognitive therapy (MBCT) have been shown to reduce distress in chronic pain and decrease risk of depression relapse. These standardized mindfulness (ST-Mindfulness) practices predominantly require attending to breath and body sensations. Her...
Using time-to-contact information to assess potential collision modulates both visual and temporal prediction networks
Accurate estimates of the time-to-contact (TTC) of approaching objects are crucial for survival. We used an ecologically valid driving simulation to compare and contrast the neural substrates of egocentric (head-on approach) and allocentric (lateral approach) TTC tasks in a fully factorial, event-related fMRI design. Compared to colour control task...
Multi-voxel pattern analysis in human hippocampal subfields.
Published in Frontiers in human neuroscience
A complete understanding of the hippocampus depends on elucidating the representations and computations that exist in its anatomically distinct subfields. High-resolution structural and functional MRI scanning is starting to permit insights into hippocampal subfields in humans. In parallel, such scanning has facilitated the use of multi-voxel patte...
The modulatory influence of the functional COMT Val158Met polymorphism on lexical decisions and semantic priming.
Published in Frontiers in human neuroscience
The role of the prefrontal Cortex (PFC) in higher cognitive functions - including working memory, conflict resolution, set shifting and semantic processing - has been demonstrated unequivocally. Despite the great heterogeneity among tasks measuring these phenotypes, due in part to the different cognitive sub-processes implied and the specificity of...
