What does "brain signals traveling" even mean? The brain is highly interconnected with both forward and feedback connections at all levels. Both of the mentioned regions are always active and always sending signals bidirectionally. fMRI is a slow, low resolution approximation of brain activity, so I'd really like to know what they are actually measuring as opposed to some clearly reductive analogy of what they suspect might be an underlying cause for that observation.
