Document Summary

Behaviourist and physiologists use graphics to display degree of phase locking of neural activity or acoustic behaviour. Examples of common graphical phase locking displays include: phase or period histogram (examples is a phase histogram, interspike interval histogram. The responses from n presentations are counted and summed into discrete time bins. Response plotted as bar graph or histogram. Neural responses plotted with the wave form of a complex stimulus. Spikes counted at same starting phase of stimulus. Histogram builds up spike counts over repeated stimulus presentations and shows count over one period (but not in textbook example) Discharges usually occur only to one phase of waveform (i. e. responses are rectified) Coefficient of synchronization quantifies phase locking as synchrony of spike discharges. Clustering at a particular phase angle would suggest that there is phase locking. Timing of spikes is usually synchronized to specific period of stimulus waveform. Coefficient of synchronization quantifies phase locking as synchrony of spike discharge.
