The study describes how older adults made more false alarm errors during a Go/No-go task than their younger counterparts. They also recruited less neural resources for the execution of this task, more specifically in the middle temporal gyrus and showed delayed activation of the middle temporal gyrus, the prefrontal cortex and the pre-supplementary motor area. Among senior high-performers, they recruited more left prefrontal activation than low-performers. The study provides an interesting perspective on the longitudinal changes that take place in inhibition skills during the aging process, both at the behavioral and the neural activation levels.However, the sample is on the small side, which hinders the comparison of the different subgroups of interest. The writing is very confusing in certain sections, which makes it hard to understand the authors' point. I understand that 20 healthy subjects per group is already challenging for an MEG study. However, I still believe that such a sample size does not allow for subgrouping. Writing is considerably less messy in this version. However there are a few terms I still do not fully understand such as "neural activities" or cortical strength" and I would suggest replacing them with some more technical or specific ones.
