Theta phase

WebFeb 23, 2011 · Lubenov and Siapas (2009) found that theta phase shifts along the mediolateral and rostrocaudal axes. In theory, this traveling wave property of hippocampal theta oscillation could introduce additional variance into our theta phase measurements. The magnitude of theta phase change was estimated to be 4–8°/mm in the CA1 region … WebFeb 5, 2014 · Much of the interest in theta phase precession comes from the observations that firing phase appears to code for distance travelled through the field rather than, for example, time spent in the field , and that firing phase contributes information about the animal's location beyond that encoded by firing rate alone . This ...
