Finally, we did not control for environmental factors, so it is possible that changes in excitability measures are caused by experimental factors such as locus of attention or visual feedback (Poh et al. 2013).
Sireteanu et al. [25] have shown non-specificity of perceptual learning effects specially in visual search tasks, and thus placed the locus of plasticity for learning a visual search task at a higher level than sensory cortices.
The locus of the TwAE within the visual pathway is not known.
In typical PL models, this specificity is interpreted as an indicator of the retinotopic early visual cortical locus of learning, where different orientations are processed separately [ 2– 4].
No apparent differences were identified in their scotoma properties, duration of disease, fixation locus or visual function.
Recently, some have broadened the definition of cognitive training to include strategy training, which involves the instruction and practice of strategies to minimize cognitive impairment and enhance performance (for example, method of loci and visual imagery) and cognitive exercise [ 22].
To test whether spatial visual attention influences the processing of visual target and hand information during online control, we manipulated the locus of attention via exogenous cuing.
As a result, the physiological locus of learning in a vernier acuity task was thought to lie in the primary visual cortex, where the first stages of visual cortical processing are carried out.
In conclusion, the findings of our study imply that remapping processes, as revealed by shifting of the locus of the MAE, extend to low level visual areas.
The side-by-side plotting of both loci facilitates visual comparison and helps the user to understand the relative position of the MSU loci with respect to the QTLs.
