在这篇文章中回顾的研究与行为，电生理和功能成像的方法如何潜意识呈现掩蔽启动刺激影响反应相关的过程进行了调查。由这些引发的初始响应激活被发现是随后的抑制这种响应趋势，提供的初始激活是足够强的，以超过一个“抑制阈值”。这种双相模式被认为反映了运动控制中自我抑制回路的存在。相反，内源性反应抑制，观察到的反应相关的信号时，有意识地认为，这种外源性模式的反应抑制似乎是由皮质纹状体，而不是由前额机制介导的。总体而言，结果表明，抑制机制参与控制的反应过程，即使当电机激活是由刺激，是无法访问的有意识的意识。(C)2003 Elsevier B.V.保留所有权利。
The research reviewed in this article has investigated with behavioural, electrophysiological, and functional imaging methods how subliminally presented masked prime stimuli affect response-related processes. An initial response activation triggered by these primes was found to be followed by an inhibition of this response tendency, provided that the initial activation was strong enough to exceed an 'inhibition threshold'. This biphasic pattern is assumed to reflect the presence of self-inhibitory circuits in motor control. In contrast to endogenous response inhibition, observed when response-relevant signals are consciously perceived, this exogenous mode of response inhibition appears to be mediated by corticostriate rather than by prefrontal mechanisms. Overall, results demonstrate that inhibitory mechanisms are involved in the control of response processes, even when motor activations are triggered by stimuli that are not accessible to conscious awareness.
