Bifurcation of the neuronal population dynamics of the modified theta model: transition to macroscopic gamma oscillation
Kiyoshi Kotani, Akihiko Akao, Hayato Chiba
Interactions of inhibitory neurons produce gamma oscillations (30--80 Hz) in the local field potential, which is known to be involved in functions such as cognition and attention.…
Nonlinear phase-amplitude reduction of delay-induced oscillations
Kiyoshi Kotani, Yutaro Ogawa, Sho Shirasaka +3
Spontaneous oscillations induced by time delays are observed in many real-world systems. Phase reduction theory for limit-cycle oscillators described by delay-differential equation…
Theta-gamma cross-frequency coupling enables covariance between distant brain regions
Akihiko Akao, Sho Shirasaka, Yasuhiko Jimbo +2
Cross-frequency coupling (CFC) is thought to play an important role in communication across distant brain regions. However, neither the mechanism of its generation nor the influenc…
Suppression of macroscopic oscillations in mixed populations of active and inactive oscillators coupled through lattice Laplacian
Ikuhiro Yamaguchi, Takuya Isomura, Hiroya Nakao +3
We consider suppression of macroscopic synchronized oscillations in mixed populations of active and inactive oscillators with local diffusive coupling, described by a lattice compl…
