Feature uncertainty activates anterior cingulate cortex [PDF]
Human Brain Mapping, 2003 AbstractIn visual discrimination tasks, the relevant feature to discriminate is defined before stimulus presentation. In feature uncertainty tasks, a cue about the relevant feature is provided after stimulus offset. We used 15O‐butanol positron emission tomography (PET) in order to investigate brain activation during a feature uncertainty task.

Anterior cingulate cortex encoding of effortful behavior [PDF]
Journal of Neurophysiology, 2019 An animal’s ability to assess the value of their behaviors to minimize energy use while maximizing goal achievement is critical to its survival. The anterior cingulate cortex (ACC) has been previously shown to play a critical role in this behavioral optimization process, especially when animals are faced with effortful behaviors. In the present study,

The neural correlates of desire. [PDF]
PLoS ONE, 2008 In an event-related fMRI study, we scanned eighteen normal human subjects while they viewed three categories of pictures (events, objects and persons) which they classified according to desirability (desirable, indifferent or undesirable).

The distressed brain: a group blind source separation analysis on tinnitus. [PDF]
PLoS ONE, 2011 Tinnitus, the perception of a sound without an external sound source, can lead to variable amounts of distress.In a group of tinnitus patients with variable amounts of tinnitus related distress, as measured by the Tinnitus Questionnaire (TQ), an ...

Bayesian Prediction and Evaluation in the Anterior Cingulate Cortex [PDF]
The Journal of Neuroscience, 2013 The dorsal anterior cingulate cortex (dACC) has been implicated in a variety of cognitive control functions, among them the monitoring of conflict, error, and volatility, error anticipation, reward learning, and reward prediction errors. In this work, we used a Bayesian ideal observer model, which predicts trial-by-trial probabilistic expectation of ...
