The sequence of steps that occur in odour perception following the attachment of a
chemical to a sensory receptor is , , , and .
1. An interneuron in the cerebrum is stimulated.
2. Acetylcholine attaches to an interneuron’s dendrites.
3. A wave of depolarization moves down the sensory neuron.
4. Sodium ions start to move rapidly into the sensory neuron.
