Functional imaging of time on task and the involvement of dopaminergic and cholinergic substrates in cognitive effort and reward

The paper investigates neural substrates involved in cognitive effort and reward using neuroimaging, identifying the basal forebrain's role in sustaining task sets and cognitive efforts.

Basal forebrain and neural correlates of self-regulation traits in sustained attention

This study investigates neural correlates of self-regulation traits in sustained attention using functional imaging data, confirming increased recruitment of cholinergic substrates in the basal forebrain.

Reassessing the Neural Correlates of Social Exclusion: A Replication Study of the Cyberball Paradigm Using Arterial Spin Labelling

This study replicates previous findings of social exclusion neural correlates using arterial spin labelling but suggests these areas may also be involved in other cognitive processes.

The fMRI global signal and its association with the signal from cranial bone

The paper investigates the association between the fMRI global signal and the signal from cranial bone and subdural vessels, finding strong correlations in some individuals.

The gradient model of brain organization in decisions involving 'empathy for pain'

The paper investigates the relationship between high-level pain empathy representations and cortical deactivations in a decision-making task using representational similarity analysis.

Segregation, connectivity, and gradients of deactivation in neural correlates of evidence in social decision making

The paper identifies two distinct neural networks associated with evidence in social decision making and explores their connectivity and deactivation gradients in associative cortex.
