While the spinal cord is not undergoing direct task-induced injury in this model, these findings indicate that repetitive high force tasks induce central neural responses associated with pain behaviors.
Then, we evaluated how these two tasks induce different patterns of connectivity.
Neuroimaging research has shown that different cognitive tasks induce relatively specific activation patterns, as well as less task-specific deactivation patterns.
However, concerns exist regarding confounds like stress, increased locomotor activity levels, and decreased motivation to perform operant tasks induced by the methods employed.
As it is still unknown whether the conventional BCI induction strategies that use different the types of stimuli and/or mental tasks induce cortical reorganization for disabled users.
The results revealed that the l/r working memory tasks induced augmented activation specifically in the right middle frontal gyrus (BA9, 46) and the right superior parietal lobule (BA7), compared with the b/n or d/n tasks.
In terms of presence and strength of each component, the tasks induced the same or different involvement loads: control (−N, −S, −E), definition (+N, −S, +E), combining (+N, −S, +E), translation (+N, −S, +E) and writing (+N, −S, ++E).
This statistical test showed that different TASKs induce statistically significant differences (p≪0.001) in the distribution of total strength, regardless of the ROIs, for all the frequency bands.
In most cases, performance of the HRHF task induced the greatest tissue degenerative changes, while performance of moderate level tasks induced bone adaptation and a suggestion of muscle adaptation.
Both high force tasks induced median nerve macrophage infiltration, spinal cord sensitization (increased substance P), grip strength declines and forepaw mechanical allodynia by task week 12.
