Characterization and optimization of the cell-electrode interface James J. Hickman |

| IDEA
|
The cell electrode interface can be optimized by modifying the electrode surface. The behavior of the interface can be modeled in appropriate details which makes the optimization possible. |
|
| GOAL |
Optimization of the cell-electrode interface in order to obtain high-quality extracellular action potential signals which enable the calculation of intracellular action potential shapes from the extracellular signal |
|
| APPROACH |
Combined patch clamp recording and computer modeling of the extracellular and intracellular signals at different interface conditions. |
|
| RESULTS |
We have developed a ‘data-true’ approach to modeling of the neuron-electrode junction by estimating a nonlinear dynamic model from the experimentally obtained input-output data records employing Volterra-Wiener characterization.
