A 10 nanosecond (10^-8 second) delay is detected by the bats about 75% of
the time. Bob Stites tells me that comparable performance is seen in a
species of insect-eating bird from Australia, but he didn't have the
reference handy. A number of the presenters at the Georgetown neuroscience
workshop will be discussing aspects of intraneuronal cognitive functioning
that may provide insight here. I'll post a report on the workshop to this
board next week.
