Gradient expansion approach to nonlinear superhorizon perturbations II -- a single scalar field -- (2007)

Tanaka, Yoshiharu, Sasaki, Misao

We formulate nonlinear perturbations of a scalar field dominated universe on super-horizon scales. We consider the case of a single scalar field. We take the gradient expansion approach. We adopt the...

Gradient expansion approach to nonlinear superhorizon perturbations (2006)

Tanaka, Yoshiharu, Sasaki, Misao

Using the gradient expansion approach, we formulate a nonlinear cosmological perturbation theory on super-horizon scales valid to $O(\epsilon^2)$, where $\epsilon$ is the expansion parameter...

CHOREIC MOVEMENTS IN THE MACAQUE MONKEY INDUCED BY KAINIC ACID LESIONS OF THE STRIATUM COMBINED WITH L-DOPA: PHARMACOLOGICAL, BIOCHEMICAL AND PHYSIOLOGICAL STUDIES ON NEURAL MECHANISMS (1990)

KANAZAWA, ICHIRO, KIMURA, MINORU, MURATA, MIHO, TANAKA, YOSHIHARU, CHO, FUMIAKI

In order to produce choreic movements in monkeys (Macaca species), we have used the combination of unilateral kainic acid injections into the striatum and the systemic administration of L-DOPA. Two...
