BIO310H5 Chapter Notes - Chapter 11: Central Pattern Generator, Fixed Action Pattern, Motor Neuron
Document Summary
Chapter 11: behaviour initiation, patterns, and control. Sensory side of the nervous system is responsible for: acquiring and analyzing information from the outside world. This information needs to be passed on to neurons that are responsible for generating coordinated movements. Motor patterns have different degree of complexity. They can either be simple networks that control repetitive actions, or they can be very complex. This different degree of complexity allows different amounts of flexibility. Fixed action pattern: a behaviour that is performed in a stereotype fashion in response to a specific stimuli. The all or nothing property of the fixed action pattern behaviour suggests that a neuronal decision might generate them. Decision in this sense means: the activation of a single neuronal switch in the cns start the behavioural pattern. A hierarchy can be created for this motor control system. In this system, the input is used to select the motor output.
