It has been suggested that the function of sleep is to actively clear metabolites and toxins from the brain. Enhanced clearance is also said to occur during anesthesia. Here, we measure clearance and movement of fluorescent molecules in the brains of male mice and show that movement is, in fa...
As adjectives the difference between equimolar and equimolecular. is thatequimolar is (chemistry) containing the same number of moles (of two or more compounds)while equimolecular is (chemistry) containing the same number of molecules (of two or more compounds).
