From: Recording and modeling of pinched hysteresis loops, the fingerprint of a memristor, in neurons
Results from current clamp shown for four different neurons (processed data with averaging to 100 data points per cycle). Pinched hysteresis loops were obtained in neurons 1 and 2. (a) Results from neuron 1 shown for different frequencies (0.01 Hz, 0.02 Hz, and 0.1 Hz) and an amplitude of 8 pA. (b) Results from neuron 2 shown for different amplitudes (10 pA, 14 pA, and 18 pA) and a frequency of 0.1 Hz. The green arrows indicate the trajectory of the pinched hysteresis loops. Neurons 3 and 4 in (c) do not show pinched hysteresis loops. The results of both neurons contain more noise and are thus less smooth than the results of neurons 1 and 2. The grey dashed plots show the first cycle of recordings with 0.02 Hz. For better visibility, the different colors represent first (red), second (grey), third (dark cyan) and fourth (light cyan) quarter of each cycle.
