Enhanced unblocking from sustained post-trial surprise (2013)
Journal Article

Two appetitive conditioning experiments with rats investigated the mechanisms and properties of unblocking that results from the surprising omission of an expected post-trial unconditioned stimulus (US). Experiment 1 demonstrated unblocking under cir... Read More about Enhanced unblocking from sustained post-trial surprise.

Looking for a face in the crowd: Fixation-related potentials in an eye-movement visual search task (2013)
Journal Article

Despite the compelling contribution of the study of event related potentials (ERPs) and eye movements to cognitive neuroscience, these two approaches have largely evolved independently. We designed an eye-movement visual search paradigm that allowed... Read More about Looking for a face in the crowd: Fixation-related potentials in an eye-movement visual search task.

Can Adults With Autism Spectrum Disorders Infer What Happened to Someone From Their Emotional Response? (2013)
Journal Article

Can adults with autism spectrum disorders (ASD) infer what happened to someone from their emotional response? Millikan has argued that in everyday life, others' emotions are most commonly used to work out the antecedents of behavior, an ability terme...

Motor excitability during movement preparation in Tourette syndrome (2013)
Journal Article

Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the occurrence of motor and vocal tics. TS has been linked to the impaired operation of cortical-striatal-thalamic-cortical circuits that give rise to hyper-excitability of cort...

Visual motion integration is mediated by directional ambiguities in local motion signals (2013)
Journal Article

The output of primary visual cortex (V1) is a piecemeal representation of the visual scene and the response of any one cell cannot unambiguously guide sensorimotor behavior. It remains unsolved how subsequent stages of cortical processing combine (“p... Read More about Visual motion integration is mediated by directional ambiguities in local motion signals.

Self-Related Consequences of Death Fear and Death Denial (2013)
Journal Article

This study explores self-related outcomes (e.g., esteem, self-concept clarity, existential well-being) as a function of the interaction between self-reported levels of death fear and death denial. Consistent with the idea that positive existential gr... Read More about Self-Related Consequences of Death Fear and Death Denial.

Temporary inhibition of dorsal or ventral hippocampus by muscimol: Distinct effects on measures of innate anxiety on the elevated plus maze, but similar disruption of contextual fear conditioning (2013)
Journal Article

Studies in rats, involving hippocampal lesions and hippocampal drug infusions, have implicated the hippocampus in the modulation of anxiety-related behaviors and conditioned fear. The ventral hippocampus is considered to be more important for anxiety... Read More about Temporary inhibition of dorsal or ventral hippocampus by muscimol: Distinct effects on measures of innate anxiety on the elevated plus maze, but similar disruption of contextual fear conditioning.

Cortical thickness, cortical and subcortical volume, and white matter integrity in patients with their first episode of major depression (2013)
Journal Article

Background The uncertainty over the true morphological changes in brains with major depressive disorder (MDD) underlines the necessity of comprehensive studies with multimodal structural brain imaging analyses. This study aimed to evaluate the dif... Read More about Cortical thickness, cortical and subcortical volume, and white matter integrity in patients with their first episode of major depression.

Oxytocin Receptor Genotype Modulates Ventral Striatal Activity to Social Cues and Response to Stressful Life Events (2013)
Journal Article

Background Common variants in the oxytocin receptor gene (OXTR) have been shown to influence social and affective behavior and to moderate the effect of adverse experiences on risk for social-affective problems. However, the intermediate neurobiologi... Read More about Oxytocin Receptor Genotype Modulates Ventral Striatal Activity to Social Cues and Response to Stressful Life Events.

Learning on the IGT follows emergence of knowledge but not differential somatic activity (2013)
Journal Article

The importance of unconscious autonomic activity vs. knowledge in influencing behavior on the Iowa Gambling Task (IGT) has been the subject of debate. The task's developers, Bechara and colleagues, have claimed that behavior on the IGT is influenced...

Risk Prediction Error Coding in Orbitofrontal Neurons (2013)
Journal Article

Risk is a ubiquitous feature of life. It plays an important role in economic decisions by affecting subjective reward value. Informed decisions require accurate risk information for each choice option. However, risk is often not constant but changes... Read More about Risk Prediction Error Coding in Orbitofrontal Neurons.

Incentives, expertise, and medical decisions: Testing the robustness of natural frequency framing (2013)
Journal Article

Is the masked priming same-different task a pure measure of prelexical processing? (2013)
Journal Article

To study prelexical processes involved in visual word recognition a task is needed that only operates at the level of abstract letter identities. The masked priming same-different task has been purported to do this, as the same pattern of priming is...

Event-related fMRI at 7T reveals overlapping cortical representations for adjacent fingertips in S1 of individual subjects (2013)
Journal Article

Recent fMRI studies of the human primary somatosensory cortex have been able to differentiate the cortical representations of different fingertips at a single-subject level. These studies did not, however, investigate the expected overlap in cortical...

Extraversion differentiates between model-based and model-free strategies in a reinforcement learning task (2013)
Journal Article

Prominent computational models describe a neural mechanism for learning from reward prediction errors, and it has been suggested that variations in this mechanism are reflected in personality factors such as trait extraversion. However, although trai... Read More about Extraversion differentiates between model-based and model-free strategies in a reinforcement learning task.

Adaptation to implied tilt: extensive spatial extrapolation of orientation gradients (2013)
Journal Article

To extract the global structure of an image, the visual system must integrate local orientation estimates across space. Progress is being made toward understanding this integration process, but very little is known about whether the presence of struc...

Randomized controlled trial of computerized cognitive behavioural therapy for depressive symptoms: effectiveness and costs of a workplace intervention (2013)
Journal Article

Background Depression and anxiety are major causes of absence from work and underperformance in the workplace. Cognitive behavioural therapy (CBT) can be effective in treating such problems and online versions offer many practical advantages. The aim...

Decoding working memory of stimulus contrast in early visual cortex (2013)
Journal Article

Most studies of the early stages of visual analysis (V1-V3) have focused on the properties of neurons that support processing of elemental features of a visual stimulus or scene, such as local contrast, orientation, or direction of motion. Recent evi... Read More about Decoding working memory of stimulus contrast in early visual cortex.

Probabilistic inference of short-term synaptic plasticity in neocortical microcircuits (2013)
Journal Article

Short-term synaptic plasticity is highly diverse across brain area, cortical layer, cell type, and developmental stage. Since short-term plasticity (STP) strongly shapes neural dynamics, this diversity suggests a specific and essential role in neural...

Do personality traits predict individual differences in excitatory and inhibitory learning? (2013)
Journal Article

Conditioned inhibition (CI) is demonstrated in classical conditioning when a stimulus is used to signal the omission of an otherwise expected outcome. This basic learning ability is involved in a wide range of normal behavior – and thus its disruptio...
