Working memory (WM) describes the dynamic process of maintenance and manipulation information over a certain time delay. Neuronally, WM recruits distributed network cortical regions like visual dorsolateral prefrontal cortex as well subcortical hippocampus. How input dynamics subsequent neural impact remains unclear though. To answer this question, we combined analysis behavioral capacity with measuring through task-related power spectrum changes, e.g., median frequency (MF) in functional magnetic resonance imaging (fMRI). We show that processing dynamics, task structure's specific timescale, leads to changes unimodal cortex's corresponding timescale which also relates working capacity. While more transmodal hippocampus its balance across multiple timescales or frequencies. In conclusion, here relevance both different for uni - subject's performance.

Background Humans continuously maintain and adjust posture during gait, standing, sitting. The difficulty of postural control is reportedly increased unstable stances, such as unipedal standing with closed eyes. Although balance slightly impaired in healthy young adults they rarely fall. brain recognizes the change sensory inputs outputs motor commands to musculoskeletal system. However, changes cortical activity associated maintenance following periods instability require further clarified. Methods In this study, a total 15 male participants performed two tasks center pressure displacement electroencephalogram were simultaneously measured. addition, correlation between amplitude power spectral density was analyzed. Results movement larger than bipedal under both eye open conditions. It also condition compared when eyes standing. high-frequency bandwidth (1–3 Hz) more difficult easier ones, suggesting that continuous required. densities theta frontal area gamma parietal higher ones across tasks, these correlate increase displacement. Conclusions Taken together, specific activation patterns neocortex are suggested be important for stances.

The ground reaction force (GRF) recorded by a platform when person stands upright lies at the interface between neural networks controlling stance and body sway deduced from centre of pressure (CoP) displacement.
