Topic: time shifts

Interareal phase coherence (PC) is a common way to measure the synchronization of neural activity between different brain regions based on the phase relations between their oscillatory signals (Bastos et al., 2015, Curr Opin Neurobiol). Typically, PC between two sites (e.g. between visual areas V1 and V4) is calculated at t = 0 (Lachaux et al., 1999, Hum Brain Mapp.; Grothe et al., 2012, J Neurosci.), meaning no time delay between the signals of the two sites is included in PC calculations. However, neuronal signal exchange between brain areas requires significant amounts of time. Therefore, c
