Document Summary

Neuro 101 midterm ii review: sensory systems: explain the difference between sensation and perception. Know william james and his view of sensation/perception (from lecture). Sensation: occurs when receptors for sensory systems register energy from external environment (sound/light/odor/etc. : receptor level, initial neurons, transform energy into generator/spike potentials (graded or action potentials) William james: father of american psychology, wrote principles of psychology : opinion on sensation/perception: sensation triggers perception, which can trigger an emotional response; perception generates consciousness. Perception/sensation correlated, but fundamentally independent: refer to different levels in sensory processing, one can occur with or without the other. Example of sensation without perception: adaptation cells stop stop responding as strongly, habituation learned. Labeled lines: receptors specific to certain sensations that trigger certain generalized perceptions: enable us to readily discriminate many differences among stimuli. Ex: stimulation of optic nerve leads to visual experience. Cross-modal sensations experience of sensation in one modality causes a sensation in another.
