Right.  Of course, it depends on what he is talking about (and it may
be he does not know) when he asks about conductivity.

For example, while there are probably more fibers that normally
conduct from the cortex rather than to the cortex, it is also notable
that all these axons are capable of conducting action potentials in
either direction.
