WebNov 13, 2024 · The encoding of a fully temporal code is dependent on the precise timing of all spikes. Evidence from neuroscience suggests that spike-timing can be incredibly precise and repeatable. Timings are related to a certain (internal or external) event in a fully temporal code (such as the onset of a stimulus or spike of a reference neuron). Latency ... Webcodes also use different subsets of cells in signaling but the latency codes turn out to need orders of magnitude less cells to achieve equivalent precision and conﬁdence levels. Another important consequence of a latency code is that it is compatible with spike timing dependent plasticity (STDP; Bi and Poo, 1998). sensory ecology definition

However, in most cases it remains unclear whether and how such … WebDec 3, 2008 · A particular example for a temporal code is the “latency code,” where the arrival time of the first spike after the onset of a stimulus contains the stimulus information (Thorpe, 1990; Gawne et al., 1996; Johansson and Birznieks, 2004; Gollisch and Meister, 2008). As a reference time for a spike in a temporal code, one typically considers ... WebTo model this idea, binary symbols can be used to mark the spikes: 1 for a spike, 0 for no spike.
