What is spike frequency adaptation?
Spike-frequency adaptation is the reduction of a neuron's firing rate to a stimulus of constant intensity. In the locust, the Lobula Giant Movement Detector (LGMD) is a visual interneuron that exhibits rapid adaptation to both current injection and visual stimuli.
How is Spike frequency calculated?
The mean spike frequency or the average firing frequency is the number of inter-spike intervals (ISI's) divided by time difference between the first and the last spike: . The time difference between the first and the last spike, tn+1 – t1, can be calculated as the sum of the n inter-spike intervals .
What is Spike accommodation?
Spike accommodation, also termed spike-frequency adaptation (Benda and Herz, 2003), is an excitation property of many neurons defined as a decreasing rate of action potential firing during a steady excitatory driving current.
What is Spike rate neuron?
In spike-rate coding, the number of spikes within a time window or the reciprocal of a single interspike interval (ISI) (1/ISI = instantaneous rate) correlates with some stimulus attribute; in this case, ISIs must be shorter than the minimum time scale of the stimulus, as explained by the Nyquist theorem (Theunissen ...
