It’s worth noting that in neuro speak, inhibition does not necessarily correlate with what would appear to be a “dis/inhibited” person; it’s referring to a specific process where signals are blocked from propagating, and because the brain is made of a complex web of inter-modulatory loops, this can show up in unintuitive ways

e.g. signals from the default mode network getting in the way of task-oriented behavior, which can result in people appearing “inhibited” where in actuality they’re failing to inhibit irrelevant internal signals and (errant bottom-up) attention to them (this is the case in ADHD).

Think of it like a relay with a normally closed contact.
