Parallel processes of temporal control in the supplementary motor area and the frontoparietal circuit
Durations in the several seconds' range are cognitively accessible during active timing. Functional neuroimaging studies suggest the engagement of the basal ganglia (BG) and supplementary motor area (SMA). However, their functional relevance and arrangement remain unclear because non-timing cognitive processes temporally coincide with the active timing. To examine the potential contamination by parallel processes, we introduced a sensory control and a motor control to the duration-reproduction task. By comparing their hemodynamic functions, we decomposed the neural activities in multiple brain loci linked to different cognitive processes. Our results show a dissociation of two cortical neural circuits: the SMA for both active timing and motor preparation, followed by a prefrontal–parietal circuit related to duration working memory. We argue that these cortical processes represent duration as the content but at different levels of abstraction, while the subcortical structures, including the BG and thalamus, provide the logistic basis of timing by coordinating the temporal framework across brain structures.
期刊介绍:
PsyCh Journal, China''s first international psychology journal, publishes peer‑reviewed research articles, research reports and integrated research reviews spanning the entire spectrum of scientific psychology and its applications. PsyCh Journal is the flagship journal of the Institute of Psychology, Chinese Academy of Sciences – the only national psychology research institute in China – and reflects the high research standards of the nation. Launched in 2012, PsyCh Journal is devoted to the publication of advanced research exploring basic mechanisms of the human mind and behavior, and delivering scientific knowledge to enhance understanding of culture and society. Towards that broader goal, the Journal will provide a forum for academic exchange and a “knowledge bridge” between China and the World by showcasing high-quality, cutting-edge research related to the science and practice of psychology both within and outside of China. PsyCh Journal features original articles of both empirical and theoretical research in scientific psychology and interdisciplinary sciences, across all levels, from molecular, cellular and system, to individual, group and society. The Journal also publishes evaluative and integrative review papers on any significant research contribution in any area of scientific psychology
