 The second component of the Bereitschaftspotential (BP2 oder BPlate) is generated by the primary motor cortex M1, and BP2 is asymmetrical with unilateral movements, namely dominant over the contralateral hemisphere.In Ulm, Deecke had projects with the DFG (German Research Foundation), and a productive team with research on the vestibular system and the motor system emerged including vestibular and neck interaction.In 1982 during Deecke's visiting professorship on invitation of Hal Weinberg in Vancouver, the Magnetoencephalographic-(MEG-) analogue of the Bereitschaftspotential, the Bereitschaftsmagnetfeld (Bereitschaftsfield, BF) was first recorded.
