ELI5: What is happening to the human body during a seizure?

What are causes of seizures? And what is our body specifically trying to accomplish during the process of a seizure?

I know a little bit about this, so if someone wants to elaborate they can. 

So every time you do something, your brain has a neuron that fires. Anything from a thought to an action creates a pulse from a neuron. 

You see something, a neuron fires, you want to move your arm, another couple fire. 

When you're having a seizure, neurons begin to fire randomly. causing (in most cases) involuntary muscle movement and unconsciousness. 

edit: before i get comments saying there are synapses and goes over neural pathways, it's eli5.
