The method is magnetoencephalography (MEG), and the work you described
was done in the Cold Temperature Lab in Otaniemi (Helsinki University
of Technology, Espoo, Finland). 
They have a 122 channel Neuromag device... The reference you are
looking for is: Salmelin, R., Hari, R., Lounasmaa, O: & Sams, R. (1994)
Dynamics of brain activation during picture naming. Nature, 368, 463-465.
hope this helps,
