Abstract
A method and apparatus for evaluating the response of a biological or nonbiological system to an external or internal stimulus (optical, thermal, auditory, tactile, taste, electrical, magnetic, chemical, biochemical, pharmacological, hormonal, internal cellular transformations, etc.). The system is exposed to the stimulus while at least one electrophysiological signal is recorded. The recorded data is digitized, stored, and analyzed using RQA or other suitable techniques to ascertain the properties of the system's response to the stimulus.

A method for evaluating the effects of a stimulus on a system, said method comprising the steps of:
- while said system is exposed to a stimulus, monitoring at least one time-dependent output signal of said system;
- recording said output signal;
- digitizing said recorded signal;
- applying a unitary transformation to said digitized signal;
- transforming said digitized signal to the time domain;
- unfolding said transformed signal in phase space;
- applying a filter to said unfolded signal;
- and
- deriving from said filtered signal at least one quantifier characterizing a deterministic structure of said signal.
A method for evaluating the effects of a stimulus on a system, said method comprising the steps of:
- while said system is exposed to a stimulus, monitoring at least one output signal of said system;
- recording said output signal;
- digitizing said recorded signal;
- preprocessing said recorded signal,
- applying a phase-space filter to said preprocessed signal;
- and
- deriving from said filtered signal at least one quantifier characterizing a deterministic structure of said signal.
An apparatus for evaluating the effects of a stimulus on a system, said apparatus comprising:
- means for monitoring at least one time-dependent output signal of said system,
- means for digitizing said output signal;
- means for preprocessing said digitized signal;
- phase-space filter means for removing nonuseful portions of said digitized signal;
- and
- means for generating at least one quantifier characterizing a deterministic structure of said phase-space-filtered signal.
