As in prior years, the University will adopt a schedule for summer office hours which varies slightly from the normal schedule followed during the academic year. Members of the staff who are required to work on a holiday will be compensated in accordance with the University s published holiday policy. Please note that the Class of 2004 arrives on Friday, August 25 . Some staff will be required to be on duty for the Labor Day holiday, Monday, September 4. The brain and thus behavior and cognition to a considerable extent are at the mercy of the infor-mation provided by sensory systems.
Sense organs function like biological interfaces between the environment and the organism.
They enable an animal to draw a picture of its environment sufficiently detailed to be used for the guidance of its behavior. This applies to a protozoan in the same way it does to a fish, a monkey, and humans. However, the sensory worlds animals live in are highly filtered, species-specific, and diverse. They can only be fully understood in a broad and organismic context. Examples will be given to illustrate this at several levels of organization and to clarify a few principles at work when sensory information is acquired and used by the organism in a way that obviously makes sense.
