the brain

emporal lobe

This lobe controls two senses: hearing and smell. It also helps to control emotion, memory, speech and behaviour.

If a seizure affects this part of your brain:

* You may smell strange smells (such as onions being fried) and hear odd sounds that aren't really there
* You may get an odd feeling in your stomach
* Your speech may be slurred
* You may have changes in your mood and behaviour. For example, you may get déjà vu (when something feels familiar even though it hasn't happened before).So, I believe the sinuses that trigger the vertigo are agervating this part of the brain,this would explain the strange odd stong odders I smell when I get vertigo.
