outputs from conscious mental activity

Conscious memory has (maybe) two, immediately observable output buffers :

1. Efferent signals, of the Motor Nervous System

2. Simulated (multi-modal) sense imagery, in the Imagination 

Less immediately observable buffers would include :

3. Subconscious thinking

4. Autonomic Nervous System 

I used to think about this a lot in college. Part of the broader anthropology of cognitive science, included trying to figure out what Eastern traditions from Vedic, to Buddhist, to Martial ... meant by various named concepts for mental activity, and effects which are either directly or indirectly observable. 

For example, one of the simplest training domains is 1. where you study the conscious relaxation and flexing of muscles. Slightly more complicated is 4. via 1., much of which has already flowed into modern military, self-care, and martial arts curricula.
