Document Summary
Experience is highly subjective part 1: sensation & perception. Perception: involves the processing, organization and interpretation of sensory signals in the brain, which results in an internal relationship of the stimuli and your conscious experience of it. Sensation: involves the detection of external stimuli (ex: light, pressure, odours) responses to those stimuli, and the transmission of these responses to the brain. Taking the stimuli (from the world) and moving it to your brain to make sense of it. Stimuli need to be translated into chemical or electrical signals for you brain to understand them. Transduction: process by which sensory receptors pass impulses to connecting neurons when they receive stimulation. Ex: from pressure on the skin, in the case of touch. Most of this information (not smell) goes first to the thalamus, before being directed to a particular part of the cortex, where the information is then interpreted as sight, smell etc.
