From: Recording and modeling of pinched hysteresis loops, the fingerprint of a memristor, in neurons
Results from voltage clamp with holding potential (HP) of 0 mV shown for three different neurons. Pinched hysteresis loops were exhibited by neurons 8 and 9. (a) Results of neuron 8 shown for different frequencies (0.01 Hz, 0.02 Hz, and 0.05 Hz) and an amplitude of 12 mV. (b) Results of neuron 9 shown for different amplitudes (8 mV, 12 mV, and 16 mV) and frequency of 0.02 Hz. The green arrows indicate the trajectories of the pinched hysteresis loops. Neuron 10 in (c) did not exhibit a pinched hysteresis loop. The result of neuron 10 contains more noise and is thus less smooth than the results of neurons 8 and 9. The number of data points per cycle is around 100. For better visibility, the different colors represent first (red), second (grey), third (dark cyan) and fourth (light cyan) quarter of each cycle. The first cycle of recordings with 0.02 Hz and the first four cycles of the recording with 0.05 Hz are presented as grey dashed plots.
