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.

Genetic polymorphism of CYP2C19 and subcortical variability in the human adult brain

This study examines the association between CYP2C19 genetic polymorphism and subcortical brain volume in adults, finding a gender-specific link between CYP2C19 activity and brain structure.

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.

Signals of anticipation of reward and of mean reward rates in the human brain

This study uses reinforcement learning models to investigate brain regions involved in processing reward expectations and mean reward rates, identifying distinct brainstem regions associated with mean reward rates.

Choosing between personal values: The Pavlovian substrates of intrinsic preferences

The paper identifies neural substrates involved in choosing between intrinsic life values, finding amygdala activation instead of typical consumer choice circuits.
