Do neurons process information by relative intervals in spike trains?
Neuroscience and Biobehavioral Reviews
|January 1, 1982
Summary
Neurons may process information using relative durations of action potential intervals, termed "bytes." This study presents evidence for these unrecognized interval patterns in published neural data, suggesting a new hypothesis for neural coding.
Area of Science:
- Neuroscience
- Computational Neuroscience
- Information Theory
Background:
- Neurons communicate via action potentials, with interval timing being a key feature.
- Existing models primarily focus on spike rate, potentially overlooking other coding mechanisms.
Purpose of the Study:
- To propose and provide preliminary evidence for a novel neural coding hypothesis based on relative durations of action potential intervals.
- To investigate the potential for 'bytes' of intervals to represent information within neural processing.
Main Methods:
- Re-examination of published illustrations of neural spike trains.
- Identification of patterns in the relative duration of adjacent and successive inter-action potential intervals.
Main Results:
- Evidence of 'byte patterns' in interval durations was observed in existing published data.
- These patterns were present even when not recognized by the original authors.
Conclusions:
- The relative-interval-pattern concept is a plausible scientific hypothesis for neural coding.
- Further specific testing is warranted to determine the validity and applicability of this interval-pattern code.
