Nerves alone do not ctrl behaviour, interaction b/w animal + environment very important. Stimulating a behaviour fixed action patterns (faps) instinctive class of behaviours: performed perfectly first time and w/o pratice/tuition instinctive behaviours not genetically determined + can be modified. Yawns classified under this behaviour (6 seconds, fully open mouth, nearly impossible to stop)
