“…The anatomical location of the control areas that are modulated by the congruency between unconscious primes and visible target stimuli used in this study seems to be consistent with the view that inverse priming is generated in the response system (Boy and Sumner, 2010;Jaśkowski and Verleger, 2007;Klapp and Hinkley, 2002;Lleras, and Enns, 2006;Schlaghecken and Eimer, 2002) rather than at perceptual levels of processing (Huber, 2008;Krüger and Mattler, 2012;Krüger et al, 2011;Mattler, 2006Mattler, , 2007Sohrabi and West, 2009). Clearly, this interpretation depends on the current functional specification of the responsive brain areas.…”

“…However, some authors have suggested that the NCE may arise from processes that are entirely perceptual or even attentional3435. Indeed, the mask-induced priming hypothesis proposes that the NCE may be produced by positive priming of the alternative response instead of motor inhibition3436.…”

While it is increasingly recognized that voluntary movements are produced by an interaction between conscious and unconscious processes, the role of the latter in Parkinson's disease has received little attention to date. Here, we administered a subliminal masked prime task to 15 Parkinson's disease patients and 15 age-matched healthy elderly subjects. Compatibility effects were examined by manipulating the direction of the arrows and the interstimuli interval. Analysis of the positive compatibility effect revealed performance differences between the most and the least affected hand in Parkinson's disease patients. Additionally, patients did not show the same tendency toward a negative compatibility effect as compared to elderly controls. These novel findings provide evidence supporting the role of basal ganglia circuits in controlling the balance between automatic motor response facilitation and inhibition.

“…Some authors argue for reciprocal inhibition processes involving only the motor system (Praamstra & Seiss, 2005), whereas others suggest involvement of the frontal cognitive system, through attentional neuromodulation (e.g. Sohrabi & West, 2009). In line with the latter theory, we showed a pattern of activation similar to what happens in traditional interference task such as the Stroop task, the EFT, or the Simon task (Wager et al, 2005;Nee et al, 2007), suggesting that unconscious information can influence the cognitive control system.…”

Masked prime tasks have shown that sensory information that has not been consciously perceived can nevertheless modulate behavior. The neuronal correlates of behavioral manifestations of visuomotor priming remain debated, particularly with respect to the distribution and direction (i.e. increase or decrease) of activity changes in medial frontal areas. Here, we predicted that these discrepant results could be accounted for by two automatic and unconscious processes embedded in this task: response conflict and facilitation. We used event-related functional magnetic resonance imaging (fMRI), as 24 healthy participants had to respond, as fast as possible, to a target arrow presented immediately after a subliminal masked prime arrow. There were three experimental conditions defined by the prime-target relationship: compatible, incompatible, and neutral. The classical visuomotor priming effect was reproduced, with relatively longer reaction times (RTs) in incompatible trials. Longer RTs in incompatible than in neutral trials were specifically associated with stronger blood oxygen level-dependent (BOLD) activity in a conflict-related network comprising the anterior cingulate cortex and right frontal associative areas. Motor response facilitation as shown by shorter RTs in compatible than in neutral trials was associated with reduced activation in a motor preparation network including the medial and lateral premotor cortices, as a result of the repetition suppression of the fMRI BOLD signal. The present results provide new insights into automatic and unconscious visuomotor priming processes, suggesting an involvement of either a cognitive or motor network, depending on the prime-target relationship.
