That's ok; let me go ahead and give you some tools that may help you in your research journey. These may or may not apply to your reference.
1. There's a 1:1 correspondence from the retina, through the thalamus, and back to the visual cortex. The term used is the retinotopic map. In other words, because of this causal chain from the retina to the cortex, the retina is fully represented in the cortex. Because of this, any brain scan of this area will not actually be observing consciousness, it's just observing the flow of information from the retina. The parts of the visual system that seem to correlate most with visual consciousness are further upstream, either in the ventral stream or the dorsal stream. From what I remember, I think studies with binocular rivalry placed the correlation most heavily in the IT region of the ventral stream. So when you read through your reference look for these areas. Are they scanning the visual cortex, V1, or are they scanning further upstream.
2. There's a double dissociation between perception and imagery. In other words, seeing something vs. imagining something. One paper that showed up in my attempt to Google your reference made mention of imagery. Just keep in mind these are not the same thing, and shouldn't be localized in the same region, though they may share some overlap. So check if the researcher makes mention of that, and tells you what region they're scanning for each task.
That's pretty much it. Good luck!
