Is there any casual relationship between alpha-band activity and converting spacial attention #7

Thank you for presenting! In your paper, you finally concluded that "alpha-band activity plays a central role in covert orienting in a range of paradigms". Your results from the experiments show that alpha-band activity varies with covert orienting. But how do you decide that alpha-band activity is playing a role in the covert orienting, not that it's influenced by covert orienting?

Great question. We do not have causal evidence, which would require manipulation of brain activity. So, my claims about the "central role" come with the caveat that the direction of causality is not certain.
