Definition
The spike-triggered average (STA) is a measure to relate a continuous signal and a simultaneously recorded spike train. It represents the average signal taken at the times of spike occurrences and with proper normalization is equivalent to the cross-correlation between the continuous signal and the spike train.
Detailed Description
The STA is widely used to study the temporal relationship between a spike train and a simultaneously recorded continuous signal, such as the local field potential (Eckhorn et al. 1988; Gray and Singer 1989; Murthy and Fetz 1996; Fries et al. 2001; Okun et al. 2010; Denker et al. 2011), membrane potential (Matsumura et al. 1996; Lampl et al. 1999; Poulet and Petersen 2008), synaptic conductance (under dynamic clamp, Gauck and Jaeger 2000) and electromyogram (McKiernan et al. 1998). Even non-physiological signals, such as electric stimulation to a single neuron (Mainen and Sejnowski 1995)...
