Significance of phase-locking measurements as a test for neural encoding models

摘要

The significance of phase-locking measurements is discussed by comparing the phase-locking behaviour of three structurally similar neural encoders. They are the integrator with dead time, the self-inhibited integrate-and-fire system with a voltage dependent inhibitory quantum and the (already analysed) leaky integrator. The analysis shows significant differences between these systems; the loss of phaselocking as the input modulation depth increases is typical of the leaky integrator model. Moreover, the analysis performed brings out the importance of the problem of attractiveness in analysing the phaselocking of neural encoder models.
