Greater Neural Pattern Similarity Across Repetitions Is Associated with Better Memory
This result addresses a longstanding debate in the study of memory by showing that successful episodic memory encoding occurs when the same neural representations are more precisely reactivated across study episodes, rather than when patterns of activation are more variable across time. Expand
Engagement of large-scale networks is related to individual differences in inhibitory control
Results clearly show a relationship between individual differences in stopping ability in specific activated networks, including regions known to be critical for the behavior, and highlight the usefulness of using dimensionality reduction to increase the power to detect brain/behavior correlations in individual differences research.

Common neural substrates for inhibition of spoken and manual responses.
A functional dissociation of left and right IFC in initiating versus inhibiting vocal responses is suggested, and it is suggested that manual responses and speech acts share a common inhibitory mechanism localized in the right I FC and pre-SMA. Expand
Neural bases of asymmetric language switching in second-language learners: An ER-fMRI study
The results suggest that neural correlates of language switching differ depending on the direction of the switch and that there does not seem to be a specific brain area acting as a "language switch". Expand
Neural correlates of envisioning emotional events in the near and far future
It is argued that the anterior part of the vmPFC might assign emotional values to mental representations of future events that pertain to long-term goals, and the caudate nucleus might support more concrete simulations of action plans to achieve rewarding situations in the near future. Expand
Abnormal affective decision making revealed in adolescent binge drinkers using a functional magnetic resonance imaging study.
Results showed that binge drinkers performed worse on the Iowa Gambling Task and showed higher activity in the subcomponents of the decision-making neural circuitry implicated in the execution of emotional and incentive-related behaviors, namely, the left amygdala and insula bilaterally. Expand
Functional dissociations of risk and reward processing in the medial prefrontal cortex.
Using functional magnetic resonance imaging and a task that simulates risky decisions, it is found that the dorsal region of the medial prefrontal cortex was activated whenever a risky decision was made, but the degree of this activity across subjects was negatively correlated with their risk preference.

The Neural Substrates of Visual Perceptual Learning of Words: Implications for the Visual Word Form Area Hypothesis

The results confirm conjecture that the fusiform visual word form area is not dedicated to words, and visual expertise acquired with training reduces rather than increases its activity. Expand
Transformed Neural Pattern Reinstatement during Episodic Memory Retrieval
Strong pattern reinstatement is found in the frontoparietal cortex, but not in the ventral visual cortex, that represents visual details, suggesting that memory retrieval is not a faithful replay of past event but rather involves additional constructive processes to serve adaptive functions. Expand
Language experience shapes fusiform activation when processing a logographic artificial language: An fMRI training study
The results suggest that visual familiarity, phonological processing, and semantic processing all make significant but different contributions to shaping the fusiform activation. Expand
