Extracellular electrical recordings of Pseudo-nitzschia fraudulenta. (a) Current response with time comprising dark and light exposure. Grow light refers to a flux of 120 µmol m−2 s−1. (b) Histogram of current spikes counted in 45 minutes as a function of light intensity. The current evolves from sporadic and weak, through asynchronous and bipolar signals, to strong quasi-periodic oscillations. Low light indicates a flux of 50 µmol m−2 s−1. (c) Magnified view of sporadic single cell spike. (d) Zoom in on region with asynchronous bipolar spikes (e) Quasi-periodic current oscillations.
