Cause and Effect-a loop

Every morning as we wake up groggy eyed we have set certain chains of events in motion. The brain stem sends little puffs of nitric oxide to thalamus, another part, which then directs itself elsewhere. Thalamus was earlier thought to be a fairly primitive structure and now it is thought to be more like a Club bouncer who checks out who goes in and who doesn’t.
Nitric acid a two atom molecule is the key component in processing information. Thu though bleary eyed we survey from bed for our slippers we know what we are looking at. Cognitive processing it is called. This molecule acts like a computer booting up its operating system before running more complex programs. In short how we process is not open and shut or simple. For example vision is not a straight run between eye and cortex but more of a loop.
This is how we need to understand cause and effect.
