reflex actions

How do they work

receptor cells → sensory nuerone → relay nuerone ( in CNS ) → motor nuerone → effector

What is a synapse

1. when the impulse reaches the end of the first nueron, a chemical is released into the synapse

2. the chemical diffuses across the synapse

innate behaviour

• isn’t learnt by the animal

habituation

• happens when a stimulus is repeated time and time again, the animal stops responding to it

imprinting

• (very young animals) attatch itself to a large organism usually the parent

classic conditioning

• animals associate an existing unconditioned reflex to a new stimulus ( pavlov)

operant conditioning

• trial and error learning ( reward or punished )

training sniffer dogs

• movement of drugs

• terrorist attacks

• → developed smell ( rewarded )

police horses

• operant conditioning

• gets used to loud crowds

• gets rewarded, will remain calm under loud enviornments
