As far as I know they are assymetric like other mammals. I don't have
any info on brain lateralisation, but it might be known in the
comparative neurophysiological literature. I seem to recall that
monkeys have lateralisation, and it is not unreasonable to expect in
"high level" areas that are not strictly connected to a symmetric
outside world (lateralisation is to some extent a kind of symmetry
breaking in the brain which saves space).
