Near-field potentials index local neural computations more accurately than population spiking
Local field potentials (LFP) contain masked information. Near-field LFP (nfLFP) offers more local stimulus details than regular LFP or neuronal spiking, improving brain signal decoding.
Area of Science:
- Neuroscience
- Computational Neuroscience
- Systems Neuroscience
Background:
- Local field potentials (LFP) reflect synaptic activity but lack spatial specificity due to volume conduction.
- Distinguishing local neural processing from widespread signals is crucial for accurate interpretation of LFP data.
Conclusions:
- The local contributions to LFP (nfLFP) are optimal for reading out local computational processing.
- Regular LFP and local spiking lead to significant information loss for understanding local neural computations.
- Careful interpretation of LFP frequency bands and laminar patterns is necessary due to spectral and spatial differences.

Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....
