PS267 Lecture Notes - Lecture 7: Stimulus Modality, Neural Pathway, Neural Adaptation
Document Summary
Lecture 7 sensation and perception part 1. Chapter 5: sensation & perception: sensation & perception: what"s the difference, processing similarities across the senses, audition, olfaction, gustation, somatosensation, vision, from sensation to perception, deficits in visual perception, multimodal perception, perceptual reorganization. Processing similarities across the senses: we will discuss many similarities across sensory modalities: Each sensory modality responds to a limited range of stimuli. The perceptual experience depends on more than the raw stimulus features. Ie. pupil focuses light, outer-ear sends sound inward. Receptors transduce environmental stimuli into neural signals: sound waves, light waves, molecules into signals. Neural signals are transmitted along specific sensory nerve pathways to thalamus: smell does not go to thalamus, protects us against poison is taste path compromised smell is still there. Processing similarities across the senses: at all levels of each sensory pathway, neural connections are going in both directions. Audition: structures of the inner ear, outer ear, middle ear:
