WebMar 23, 2024 · Introduction. Phase amplitude coupling (PAC), whereby the phase of a slow neuronal oscillation modulates the amplitude of a fast oscillation is found in many brain areas in multiple species with a variety of neuronal recording techniques and plays important functional roles [1–5].In the hippocampus the phase of a 3 to 10 Hz theta … 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 …

WebMar 16, 2024 · One of the consequences of phase precession is that correlates of behaviour, such as position in space, are compressed onto the timescale of a single theta cycle and thus coincide with the time-window of STDP ( Skaggs et al., 1996b; Mehta et al., 2000; Mehta, 2001; Mehta et al., 2002 ). This combination of theta sweeps and STDP has been … Theta waves generate the theta rhythm, a neural oscillation in the brain that underlies various aspects of cognition and behavior, including learning, memory, and spatial navigation in many animals.
