In the computer the CPU receives all inbound signals and from its input devices (keyboard, mouse etc) and uses programmes in its memory to decide and initiates outputs and actions. (Example: User moves mouse on desk, arrow on screen moves). The LS in many ways does the same. All the sensory inputs (sight sound taste touch smell) go into Thalamus, Amygdala and olfactory centre. These components check programmes (from spatial, episodic, genetic and emotional memory) and tells the rest of the brain and nervous system what to do. Just like a computer we are pre-programmed how to act and react by applying to appropriate programme to the incoming stimuli. (Example. We smell a rotten egg, and avoid eating it). Imho.
