Brain Explorer - Neurotransmitters & PD...a visual model
 

For the curious or those fighting a bout of PD induced insomnia... ;)

I found this incredible resource providing a visual model of our brain's neurotransmission system and another with a model of how our brain is impacted in PD- it, of course, includes other brain disorders. It includes a brain atlas, and an entire sub-site on brain disorders including PD. Now if I could just find one that 'moved' showing how everything works in concert...this comes so close.
