Spectro-temporal interpretation of activity patterns of auditory neurons. (English) Zbl 0671.92005

Math. Biosci. 93, No. 1, 31-51 (1989).
Summary: Sensory receptors transform an external sensory stimulus into an internal neural activity pattern. This mapping is studied through its inverse. An earlier paper [see C. C. Gielen and the authors, ibid. 88, No.1, 15-35 (1988; Zbl 0637.92005)] showed that within the context of a neuron model composed of a linear filter followed by an exponential pulse generator and a Gaussian stimulus ensemble a unique “most plausible” first-order stimulus estimate can be constructed.
This method, applicable only to neurons showing phase-lock, is extended to neurons without phase-lock. In this situation second-order spectro- temporal stimulus estimates are produced; examples are given from simulation. The method is applied to activity of neurons in the auditory system of the frog.
