Something 'excitatory' has the property of causing excitation or stimulation. It's not just generally exciting but specifically triggers a response, often in a biological or neurological context. Think of it as a switch that turns on activity. It's similar to 'stimulatory,' but often used in scientific or medical fields. Unlike something inhibitory, an excitatory influence encourages action. Imagine it like a key fitting perfectly into a lock and starting an engine π.
