Can Sea Snails Fix Chemo Brain?

Aplysia Californica

It appears we have a few things in common with sea snails. In fact, neurobiolgists have long recognized the scientific possibilities of their nervous systems, using them in studies of Alzheimer’s and Parkinson’s. They are reflexive creatures, containing only about 20,000 neurons compared to the 100 billion in the typical adult brain. But the neurons are large and relay information much the same way as in humans. That simplicity helps scientists isolate how they—and we—learn.
