Senses, coordination and behaviour

What is the adequate stimulus for the sense of hearing?

What does a sensory cell produce once it picks up a stimulus?

What do we call the lowest intensity that can cause an impuls?

1. Adequate stimulus
2. Threshold value
3. impuls
4. habituation

If a stimulus does not go away for some time, it starts producing less impulses in the cell. What do we call this?

1. Adequate stimulus
