Abstract
A vast body of research suggests that the primary motor cortex is involved in motor imagery. This raises the issue of inhibition: how is it possible for motor imagery not to lead to motor execution? Bach et al. (Psychol Res Psychol Forschung. 10.1007/s00426-022-01773-w, 2022, this issue) suggest that the motor execution threshold may be "upregulated" during motor imagery to prevent execution. Alternatively, it has been proposed that, in parallel to excitatory mechanisms, inhibitory mechanisms may be actively suppressing motor output during motor imagery. These theories are verbal in nature, with well-known limitations. Here, we describe a toy-model of the inhibitory mechanisms thought to be at play during motor imagery to start disentangling predictions from competing hypotheses.
大量研究表明，初级运动皮层参与了运动想象。这就提出了一个抑制问题：运动想象怎么可能不导致运动执行？巴赫等人（Psychol Res Psychol Forschung.另一种观点认为，在运动想象过程中，抑制机制可能与兴奋机制同时积极抑制运动输出。这些理论都是口头上的，存在众所周知的局限性。在这里，我们描述了一个被认为在运动想象过程中起作用的抑制机制的玩具模型，以便开始从相互竞争的假说中分离出预测结果。
期刊介绍：
Psychological Research/Psychologische Forschung publishes articles that contribute to a basic understanding of human perception, attention, memory, and action. The Journal is devoted to the dissemination of knowledge based on firm experimental ground, but not to particular approaches or schools of thought. Theoretical and historical papers are welcome to the extent that they serve this general purpose; papers of an applied nature are acceptable if they contribute to basic understanding or serve to bridge the often felt gap between basic and applied research in the field covered by the Journal.
