What is Spontaneous Neural Firing
   - A Leaky Integrator is a Simplified Model of a Neuron
 
   - A neuron gets activation (from its dendrites)
 
   - If the activation surpasses a threshold, the neuron fires sending
       activation down its axons
 
   - If it doesn't get enough activation, the activation leaks away. Future 
       incoming activation can add to the remaining old activation to surpass
       the threshold
 
   - Neural fatigue from repeated firing plays a part
 
   - Sometimes, even with low stored activation, neurons spontaneously 
       fire
 
   - This may have something to do with not having fired in a long time. 
       Fatigue may have a flip side.
 
   - This may be a biological necessity. The neurons need to fire 
       occasionally or they develop a chemical imbalance.
 
   - Is there also a computational reason?
