Abstract
Electrical signal data from a target location are recorded and collected. A signal analyzer analyzes the signal data and determines whether characteristics of the signal data resemble noise data or whether a departure from noise is present. If the characteristics show a departure from noise, neuronal activity at the target location is indicated.
Claims28
A system of positioning a microelectrode within a tissue, the system comprising:
- a microelectrode for collecting electrical signals;
- distribution logic that generates a statistical distribution of the electrical signals;
- identification logic that identifies whether the statistical distribution resembles a noise distribution;
- a position controller for controlling the position of microelectrode, the position controller moving or not moving the electrode based on the identification of the statistical distribution.
A software product for analyzing electrical signal data collected from tissue, the software product comprising:
- first computer executable instructions that cause a computer to generate a statistical distribution of the electrical signal data where the statistical distribution has a first shape which represents noise signal data or a second shape that represents noise data with neuronal activity;
- and
- second computer executable instructions that cause a computer to analyze the statistical distribution and indicate whether neuronal activity is present in the electrical signal data based on the shape of the statistical distribution.
A method of determining a nerve discharge from a plurality of electrical signals, the method comprising the steps of:
- statistically analyzing at least one characteristic of the plurality of electrical signals and generating a distribution curve from at least one characteristic;
- determining a statistical characteristic of the distribution curve;
- and
- determining whether at least one nerve discharge signal occurs within the electrical signal data based on the statistical characteristic of the distribution curve.
