Fig. 4. (A) Electrophysiological recording of RPd7 during a magnetic stimulus
treatment. Conventions as in Fig.
2. (B) Recordings of LPd7 (Bi) and RPd7 (Bii) before and after a
single 60° clockwise rotation of the magnetic field. The white and black
bars indicate a period of 900 s. In both traces, the number of spikes
decreased after the 60° rotation. Action potentials are between 90 and 100
mV in amplitude.
