Abstract

We have designed, built, and tested a neuromorphic model of the lamprey unit pattern generator using analog VLSI CMOS circuits. The lamprey is an eel-like fish with 100 segments in the spinal cord. Our neuromorphic single-segment model utilizes 6 neurons, 4 excitatory synapses, 8 inhibitory synapses, and 6 tonic synapses with simplified biophysical properties. The chip exhibits fixed point and oscillatory behaviors similar to the numerical model of the biological spinal cord.
