Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

Advanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

Modeling And Design Of Low Impedance Microelectrodes [PDF]

, 2012
Microelectrodes are devices through which neural signals are obtained or delivered. The goals for designing microelectrodes are maximum selectivity (ability to select and record from a single cell) and minimum impedance.

On microelectrode ionophoresis

Biophysical Journal, 1984
An equation for ionophoresis in large tip microelectrodes is derived from Nernst-Planck equations for the general case of a completely dissociated electrolyte. The relation between the release of ions and the applied electric current is mainly determined by two parameters: the transference number of the ions under consideration and the diffusional leak
