20 April 2007 Results of field tests: 1. Moths detect bats up to 120 feet. 2. Bats detect moths up to 20 feet.

20 April 2007 Results of field tests: 1. Moths detect bats up to 120 feet. 2. Bats detect moths up to 20 feet. 3. Behaviorally, moth turns and flies away if bat farther than 20 feet, loops and turns if closer.

20 April 2007 Conclusion: Input from the ears is integrated in the nervous system and fed to the motor control system to generate behavior that is appropriate to the circumstances.

Inputs from the cerci are integrated in the nervous system and fed to the motor control system to generate behavior that is appropriate to the circumstances.

20 April 2007 Behavior in “higher” animals – how is the vertebrate brain organized to generate behavior?
20
20 April 2007 The vertebrate brain is regionally specialized.
21
20 April 2007
22
The vertebrate brain uses distributed processing.
23

24
Nevertheless, the vertebrate brain acts like a unified organ.

28
20 April 2007 Neural Basis of Behavior Question – How does an animal’s nervous system orchestrate its behavior? By processing relevant sensory information and using it to make decisions about what action to take.

20 April 2007 Neural Basis of Behavior Question – How does an animal’s nervous system orchestrate its behavior? By processing relevant sensory information and using it to make decisions about what action to take. In higher animals, by processing information in specialized areas of the brain.
