NEUROELECTRIC COMPUTATIONAL DEVICES AND NETWORKS

A neuroelectric device is defined by a substrate having a neuronal cell provided thereon, a stimulator for the neuron, and a transducer for detecting a signal produced in the neuron. The neuronal cell is positioned on the substrate in a predefined orientation. The neuronal cell is conveniently oriented by providing a patterned self-assembled monolayer on the substrate. In a preferred embodiment, a capacitative transducer serves as the transducer and is capable of detecting a signal propagating in the neuron. A network of neuroelectric devices that defines a logic device also is contemplated, which includes a plurality of neurons each in electrical communication with another neuron. The neurons are provided in synaptic relationship so that a signal propagating in one neuron can be attenuated upon stimulation of another neuron.
