The issues at the edge of neuroscience are clear.
The first and most important issue at the edge is the biology underlying conscious experience, particularly the biology of self-awareness: How do you study it? Where is it located in the brain? How does it develop over time?
A second problem is how is memory perpetuated to last the lifetime of an individual.
A third problem is the future of stem cell biology in the brain. To what degree will we be able to replace cells in the nervous system that die with stem cells that take on similar properties?
