Neuroscientists and researchers still do not know enough about the workings of the human brain to completely analyze its dynamics in terms of underlying chemistry or physics, according to a member of Durham's interdisciplinary consciousness group. While substantial progress has been made in mapping brain functions and the construction of a connectome, only 70% has been completed for the maggot brain, which consists of just 10,000 to 100,000 compared to the 86 billion of the human brain.
