New Neuron Production Can Be Increased In The Hippocampus Of Aged Rats

Although new neurons (green) are routinely produced in the dentate gyrus (red, neurons of the dentate gyrus) of young animals (a, b), this phenomenon drastically disappears during ageing (c, d). A low, non-psychoactive dose of a synthetic endocannabinoid receptor agonist (WIN-55,212-2) for 3 weeks promoted neurogenesis again (e, f), thus demonstrating the potential of using cannabinoids in treating learning/memory deficits occurring during normal and pathological ageing.
