As someone else mentioned this looks a bit worrying, until you realize that 5g has much lower penetration (and this experiment was carried out with tissue with no skull/skin etc surrounding it), that a live brain is actively being cooled by bloodflow, and also were you to carry out this same experiment with regular sunlight the graph would be off the charts even compared to 5g. Although research like this is definitely very important. I would just be wary of drawing conclusions without listening to the opinions of people with more knowledge in the field than you or I.
