Ambiguous Emotion Recognition in Temporal Lobe Epilepsy: The Role of Expression Intensity
Abstract The lateralization of emotion processing is cur- rently debated and may be further explored by examining facial expression recognition (FER) impairments in temporal lobe epilepsy (TLE). Furthermore, there is also debate in the literature whether...
Amygdala Functional Connectivity Is Reduced after the Cold Pressor Task
Abstract The amygdala forms a crucial link between central pain and stress systems. Previous research indicates that psychological stress affects amygdala activity, but it is less clear how painful stressors influence subsequent amygdala functional connectivity....
Better Living through Transparency: Improving the Reproducibility of fMRI Results through Comprehensive Methods Reporting
Abstract Recent studies suggest that a greater proportion of published scientific findings than expected cannot be replicated. The field of functional neuroimaging research is no exception to this trend, with estimates of false positive results ranging...
Candy and the Brain: Neural Response to Candy Gains and Losses
Abstract Incentive processing is a critical component of a host of cognitive processes, including attention, motivation, and learning. Neuroimaging studies have clarified the neural systems underlying processing of primary and secondary re- wards in...
Constraints on Decision Making: Implications from Genetics, Personality, and Addiction
Abstract An influential neurocomputational theory of the biological mechanisms of decision making, the "basal ganglia go/no-go model," holds that individual variability in decision making is determined by differences in the makeup of a striatal system...
Could Millisecond Timing Errors in Commonly Used Equipment Be a Cause of Replication Failure in Some Neuroscience Studies?
Abstract Neuroscience is a rapidly expanding field in which complex studies and equipment setups are the norm. Often these push boundaries in terms of what technology can offer, and increasingly they make use of a wide range of stimulus materials and...
Distinguishing Multi-Voxel Patterns and Mean Activation: Why, How, and What Does It Tell Us?
Abstract The introduction of multi-voxel pattern analysis (MVPA) to the functional magnetic resonance imaging (fMRI) community has brought a deeper appreciation for the diverse forms of information that can be present within fMRI activity. The conclusions...
Friendly Drug-Dealers and Terrifying Puppies: Affective Primacy Can Attenuate the N400 Effect in Emotional Discourse Contexts
Abstract Words that are semantically congruous with their preceding discourse context are easier to process than words that are semantically incongruous with their context. This facilitation of semantic processing is reflected by an attenuation of the...
Harnessing Graphics Processing Units for Improved Neuroimaging Statistics
Abstract Simple models and algorithms based on restrictive assumptions are often used in the field of neuroimaging for studies involving functional magnetic resonance imaging, voxel based morphometry, and diffusion tensor imaging. Nonparametric statistical...
How to Produce Personality Neuroscience Research with High Statistical Power and Low Additional Cost
Abstract Personality neuroscience involves examining relations between cognitive or behavioral variability and neural variables like brain structure and function. Such studies have uncovered a number of fascinating associations but require large samples,...
I Suffer More from Your Pain When You Act like Me: Being Imitated Enhances Affective Responses to Seeing Someone Else in Pain
Abstract Social-psychological research has suggested that being imitated changes the way that we experience others: We like someone who imitates us more, and the interaction with this person runs more smoothly. Whether being imitated also affects basic...
Limb-Specific Emotional Modulation of Cervical Spinal Cord Neurons
Abstract Emotional stimuli receive prioritized attentional and motoric processing in the brain. Recent data have indicat- ed that emotional stimuli enhance activity in the cervical spinal cord as well. In the present study, we used fMRI to investigate...
Mapping the Time Course of the Positive Classification Advantage: An ERP Study
Abstract The aim of the present study was to investigate the time course of the positive advantage in the expression classification of faces by recording event-related potentials (ERPs). Although neutral faces were classified more quickly than either...
Naloxone Modulates Visual Judgments of Similarity but Not Dissimilarity
Abstract Endogenous opioids have been implicated in mediating (placebo) analgesia, in reward processes, and in the regulation of socially relevant emotions. To explore their potential contributions to higher cognitive functions, we used a novel task...
Neural Networks Supporting Autobiographical Memory Retrieval in Posttraumatic Stress Disorder
Abstract Posttraumatic stress disorder (PTSD) affects the functional recruitment and connectivity between neural regions during autobiographical memory (AM) retrieval that overlap with default and control networks. Whether such univariate changes relate...
Number of Events and Reliability in fMRI
Abstract Relatively early in the history of fMRI, research focused on issues of power and reliability, with an important line concerning the establishment of optimal procedures for experimental design in order to maximize the various statisticalpropertiesofsuchdesigns.However,inrecentyears,tasks...
Probabilistic Models of Expectation Violation Predict Psychophysiological Emotional Responses to Live Concert Music
Abstract We present the results of a study testing the often- theorized role of musical expectations in inducing listeners' emotions in a live flute concert experiment with 50 participants. Using an audience response system developed for this purpose,...
Reproducibility of Functional Network Metrics and Network Structure: A Comparison of Task-Related BOLD, Resting ASL with BOLD Contrast, and Resting Cerebral Blood Flow
Abstract Network analysis is an emerging approach to functional connectivity in which the brain is construed as a graph and its connectivity and information processing estimated by mathematical characterizations of graphs. There has been little to no...
The Bivalency Effect Represents an Interference-Triggered Adjustment of Cognitive Control: An ERP Study
Abstract When bivalent stimuli (i.e., stimuli with relevant features for two different tasks) occur occasionally among univalent stimuli, performance is slowed on subsequent univalent stimuli even if they have no overlapping stimulus features. This finding...
Toward a Neurometric Foundation for Probabilistic Independent Component Analysis of fMRI Data
Abstract Improved fMRI data analysis methods hold promise for breakthroughs in cognitive and affective neuroscience. Group probabilistic independent component analysis (pICA), such as that implemented by MELODIC (Beckmann & Smith IEEE Transactions...
