General Properties of Sensory Systems Lectures OUTLINE VII. Sensory Systems: General Introduction VII.A. Basic Concepts VII.A.1 Example of an illusion VII.A.2 Different types of sensory systems VII.A.3. Sensory transduction and receptor potentials VII.A.4. Categories of sensory information VII.A.4.a Sensory modality VII.A.4.b Intensity VII.A.4.c. Duration VII.A.5. The concept of the Receptive Field (RF) VII.A.6 The concept of a map VII.A.6.a.What are maps VII.A.6.b. how do we get maps from RFs (IMPORTANT the two are DIFFERENT) VII.A.6.c. Important stimuli are over-represented in maps VII.B. The brain determines perception (rather than the physical world) VII.B.1. Explaining the flag illusion VII.B.2 Selective adaptation and illusions (also do spiral illusion) VII.B.3. Scene Analysis VII.B.3.a.

VII.A.2 Different types of sensory systems Present Flag illusion Sensory systems are those parts of the nervous system which give an organism information about the external world and the organism’s internal state. In this course we will not talk about visceroreceptors which give us information about blood pressure, blood pH, etc. NPB 101 talks about these sorts of sensory systems extensively. Sense
