2006 An asynchronous architecture for modeling intersegmental neural communication
abstract
This paper presents an asynchronous VLSI architecture for modeling the oscillatory patterns seen in segmented biological systems. The architecture emulates the intersegmental synaptic connectivity observed in these biological systems. The communications network uses address-event representation (AER), a common neuromorphic protocol for data transmission. The asynchronous circuits are synthesized using communicating hardware processes (CHP) procedures. The architecture is scalable, supports multichip communication, and operates independent of the type of silicon neuron (spiking or burst envelopes). A 16-segment prototype system was developed, tested, and implemented; data from this system are presented.

2000 Modeling Alternation to Synchrony with Inhibitory Coupling: A Neuromorphic VLSI Approach
abstract
We developed an analog very large-scale integrated system of two mutually inhibitory silicon neurons that display several different stable oscillations. For example, oscillations can be synchronous with weak inhibitory coupling and alternating with relatively strong inhibitory coupling. All oscillations observed experimentally were predicted by bifurcation analysis of a corresponding mathematical model. The synchronous oscillations do not require special synaptic properties and are apparently robust enough to survive the variability and constraints inherent in this physical system. In biological experiments with oscillatory neuronal networks, blockade of inhibitory synaptic coupling can sometimes lead to synchronous oscillations. An example of this phenomenon is the transition from alternating to synchronous bursting in the swimming central pattern generator of lamprey when synaptic inhibition is blocked by strychnine. Our results suggest a simple explanation for the observed oscillatory transitions in the lamprey central pattern generator network: that inhibitory connectivity alone is sufficient to produce the observed transition.

1995 An Analog VLSI Loser-Take-All Circuit
abstract
An analog circuit that performs a loser-take-all computation is presented. This circuit takes an array of analog input current and produces an array of binary output voltages/currents. The circuit functions such that the output at the node with the minimum input current is a non-zero constant while all of the other outputs are equal to zero. This circuit can also be used to compute the global minimum of the input array. Theory of operation for this circuit is developed and compared with experimental results.
