Information processing

Information Processing

the afferent (sensory) branch of the nervous system conveys information regarding both the external and internal environments
information processing can be divided into 4 stages:

	Structural correlate	Physiological process
1		Stimulation
2	Receptor	Transduction
3	Neural pathways	Transmission and modulation
4	Primary and association cortex	Perception

another important distinction is between UNCONSCIOUS processing --- termed SENSATION ---, which occurs at a subcortical level, and CONSCIOUS processing (i.e. PERCEPTION)
