But if you let them live in an "enriched enclosure"--the marmoset equivalent of Versailles, featuring "branches, hidden food, and a rotation of toys"--neurogenesis kicks in, along with an increase in the number and strength of synaptic connections. We contrasted neuritic outgrowth and cholinergic synaptic development in neonatal rats given different organophosphates (chlorpyrifos, diazinon, parathion) at doses spanning the threshold for impaired growth and viability. This leads to increased neuronal development and synaptic activity that enhances brain function, and it serves to improve athletic performance as well as to symptomatically improve, forestall the progression of, and possibly prevent many disease states. |
