This really applies to all drugs but I’m curious as to how getting anaesthetics injected into your bloodstream can flow through your entire body and find the exact place in your brain that it needs to target. I believe the ones that are strong enough to put you to sleep target the amygdala as well as some other areas (I could be wrong) but how is it that only those areas of the brain area affected?
In: Biology
Different brain nerves have different shaped holes that only specific shaped stuff can get inside. We put stuff with this specific shape in your body OR close enough shape OR something that is shaped like it but that blocks the hole making it stop working.
