claimExposure to credit card cues may trigger sensitivity to rewards, which manifests as an increase in reward anticipation in the striatum following the onset of a credit card logo in expectation of an imminent purchase decision.
claimIn an fMRI shopping task, credit card purchases were associated with strong activation in the striatum, which coincided with the onset of the credit card cue and was not related to product price.
procedureThe researchers selected regions of interest (ROIs) for brain analysis using masks from meta-analyses of the striatum, the ventromedial prefrontal cortex (VMPFC), and the right anterior insula (rAIC), rather than using sample-dependent anatomical definitions.
claimWhole brain contrast analyses in the study verified that striatum activation is associated with product preference, ventromedial prefrontal cortex (VMPFC) activation is associated with choice, and right anterior insula activation is associated with higher prices.
claimCredit card cues lead to reward network sensitization in the striatum, which is a distinguishing feature of cue-triggered mechanisms observed in studies of chemical addiction to substances.
claimIn an fMRI shopping task, researchers observed that activation in the striatum (a classical reward network) differentiates credit card purchases from non-purchases, but bears little relation to the price of the item.
claimPrices modulate the association of neural signals and the decision to purchase, as shown by an analysis of differential purchasing signals in the striatum.
claimThe hypothesis supported by the evidence in the study 'Neural mechanisms of credit card spending' is that the reward network, specifically the striatum, has been chronically sensitized by prior experience with credit cards.
claimCredit cards reduce sensitivity to price information via heightened striatal activation exhibited during the periods in which product price is presented to participants.
claimThe key interaction effects in the striatum remain significant after Bonferroni corrections in the study of neural mechanisms of credit card spending.
claimIn an fMRI shopping task, activation in the striatum is a weak predictor of cash purchases, but interacts with price to predict purchases of cheaper items over more expensive ones.
measurementStriatal activation is a leading predictor of purchase in the SHOP task, appearing during the product and price screens, but it loses significance by the decision point.
claimWhen using cash, positive reward-related ROI activation in the striatum is associated with purchasing only among lower-priced items, while this differential purchasing signal is near zero for higher-priced items.
claimThe presentation of the credit card stimulus itself does not affect brain activity in the target regions of interest (striatum, VMPFC, and rAIC) when neural signals are collapsed across buy and no-buy decisions.

claimStudies on functional changes in the striatum during meditation report conflicting results: Lou et al. (1999, 2005) report decreased activity in the caudate, while Lazar et al. (2000), Tang et al. (2009), and Baerentsen et al. (2010) report increases in the caudate-putamen, and Kjaer et al. (2002) report increases in the ventral striatum.
referenceBrain areas critical for their interactions with the prefrontal cortex (PFC) in emotion regulation include the amygdala, hippocampus, striatum (including the nucleus accumbens), thalamus, and insula.
claimLong-term meditators show morphological increases in gray matter volume and concentration in areas related to the Experiential-Embodied-Self (EES) network, including the cerebellum, left supplementary motor area (SMA), thalamus, caudate, striatum, and parasympathetic control centers of the medulla, according to studies by Pagnoni and Cekic (2007), Luders et al. (2009), and Vestergaard-Poulsen et al. (2009).

claimReward-related neural activity in the striatum plays a key role during the evaluation phase as consumers integrate emotional and cognitive inputs, such as pricing and perceived benefits, when comparing alternatives.
