Abstract: Previous studies have suggested that chronic cannabis use has been associated with increased blood oxygen level–dependent (BOLD) response during a response inhibition task; however, these studies primarily included males. We investigated whether gender moderated the… read more here.

DOI: 10.1016/j.neuroimage.2016.12.045

Abstract: ABSTRACT A large number of fMRI studies have shown that the temporal dynamics of evoked BOLD responses can be highly heterogeneous. Failing to model heterogeneous responses in statistical analysis can lead to significant errors in… read more here.

DOI: 10.1016/j.neuroimage.2017.06.055

Abstract: Neuroimaging research has revealed that emotion processing recruits a widespread neural network including the dorsal anterior cingulate cortex (dACC), hippocampus, and amygdala. Recent studies have started to investigate the role of the primary inhibitory neurotransmitter… read more here.

Abstract: &NA; Studies of the neural mechanisms underlying value‐based decision making typically employ food or fluid rewards to motivate subjects to perform cognitive tasks. Rewards are often treated as interchangeable, but it is well known that… read more here.

DOI: 10.1038/s41598-018-26507-0

Abstract: We investigated the BOLD response of visual cortical and sub-cortical regions to fast drifting motion presented over wide fields, including the far periphery. Stimuli were sinusoidal gratings of 50% contrast moving at moderate and very… read more here.
