Are Humans Brains Unique?
     


An interesting Edge
article by Michael Gazzaniga ponders the questions of whether humans
brains are unique among animals and, if so, what makes them unique. Are
the neurons in human brains different from those in other animals? Is
the wiring different? Is it just the size of the brain that matters? Do
comparative neuroanatomy
studies shed light on whether or not findings from rat and monkey brains
can be extrapolated to human brains? Most interesting of all are recent
genetic findings that reveal unique changes appearing at key points in
our cultural evolution
37,000 years ago with the rise of modern humans and 5800 years ago with
the rise
of agriculture. There are also signs of continuing accelerated evolution in
genes responsible for brain structure in humans. All of this is
particularly interesting when considered in relation to the attempts to
replicate human mental capabilities in robots. Michael
Gazzaniga is professor of Psychology and directory of the SAGE
Center for the Study of the Mind at the University of California Santa
Barbara.
