Neuromorphic

Neuron Coding†

There are three known types of neuron coding:

• 1. Rate Code - neuroscience have been using this coding quite successful (80th)

The rate code- the average number of action potentials/spikes per unit time

Rate code alone is insufficient for account for many sofisticated spike trains especially from a population of neurons [1].

In motor neurons, the strength of an innervated muscle flexion depends solely on the firing rate.

• Stochastic means nondeterministic or unpredictable. Random generally means unrecognizable, not adhering to a pattern.

• 2. Inter-spike interval: Frequency, Correlation, Modeling (earlier 90th)

• 3. Temporal Code (Price timing of spikes)
