Lecethin is a source of choline,which is like a stimulant for the synapses to fire better, in your brain, thereby setting up nueropathways, to help memory and cognition. A nuero pathway is like a rut in the road, if there is path for memory, and that path is maintained, by traveling along the same rut all the time, those nueral firings will always occur the same way, because the path has been made, if that makes sense. It makes it easier for the brain to find learned data, motor memory, say, for learning music, because the choline keeps the synapses "snappy". Sorry for the metaphorical explanation, its the only way I can understand things, I have no gift for straight data. Maybe I need more lecithin. Free range hens who have a lot of good sunlight and Vitamin D from sunshine, lay eggs that are loaded with lechitin, the yolks have that richness that almost coats your tongue.
