Grasping at the organization of object knowledge: testing different object-related dimensions as organizational principles of ventral temporal cortex.

The paper tests how object-related dimensions like animacy, graspability, and texture organize object representations in ventral temporal cortex using fMRI and multivariate analysis.

Subliminal beauty engages the brain's valuation circuits

This study shows that subjective value signals in the brain's valuation circuits can be computed without conscious awareness of the stimuli.

Subliminal risk influences subjective value in the ventromedial prefrontal cortex

The paper shows subliminal probability cues influence subjective value representations in vmPFC and aVS without conscious awareness, suggesting global access of subliminal information.

Neural and behavioral similarity-driven tuning curves for manipulable objects

The paper investigates how the brain represents manipulable objects based on similarity, finding that increasing similarity between objects leads to slower reaction times and weaker fMRI release from adaptation.

A structural MRI marker predicts individual differences in impulsivity and classifies patients with behavioral-variant frontotemporal dementia from matched controls

The paper develops a structural MRI signature of impulsivity using machine learning, validates it across multiple samples, and shows its diagnostic value in behavioral-variant frontotemporal dementia.

Multivariate analysis of multimodal brain structure predicts individual differences in risk and intertemporal preference

Neural and behavioral signatures of the multidimensionality of manipulable object processing.

The paper investigates the multidimensionality of manipulable object processing by analyzing behavioral and neural data to identify interpretable dimensions that guide object categorization and neural representation.

Less cortical complexity in ventromedial prefrontal cortex is associated with a greater preference for risky and immediate rewards

Disentangling hand and tool processing: distal effects of neuromodulation

The paper uses tDCS and training tasks to dissociate neural processing of hands and tools in the pMTG, showing category-specific effects and distal network influences.

A reduced level of consciousness affects non-conscious processes

This study shows that sedation affects non-conscious processes more than conscious ones, suggesting consciousness level and content are distinct.
