neuro-imaging is considered to have ignited a promising new area of research in the world of neuroscience. experiments conducted in the field of paleoneurology with the help of brain imaging that involved non-skilled and skilled tool makers shows the immense possibility of deeper understanding of the evolution of the human brain. another experiment conducted with skilled tool makers threw up further potential understanding of the co-evolution of cognitive development and technology "thus although imaging data derived from modern humans and their tool using abilities cannot offer a direct proof for the co-evolution of tool use and language they nonetheless clearly support the view that human technological social and linguistic capacities evolved together in a mutually reinforcing manner.
