Human cerebellar activity reflecting an acquired internal model of a new tool

H Imamizu, S Miyauchi, T Tamada, Y Sasaki, R Takino… - Nature, 2000 - nature.com
Theories of motor control postulate that the brain uses internal models of the body to control
movements accurately. Internal models are neural representations of how, for instance, the …

Brain mechanisms for predictive control by switching internal models: implications for higher-order cognitive functions

H Imamizu, M Kawato - Psychological Research PRPF, 2009 - Springer
Humans can guide their actions toward the realization of their intentions. Flexible, rapid and
precise realization of intentions and goals relies on the brain learning to control its actions …

[HTML][HTML] Explicit contextual information selectively contributes to predictive switching of internal models

H Imamizu, N Sugimoto, R Osu, K Tsutsui… - Experimental brain …, 2007 - Springer
Many evidences suggest that the central nervous system (CNS) acquires and switches internal
models for adaptive control in various environments. However, little is known about the …

Modular organization of internal models of tools in the human cerebellum

H Imamizu, T Kuroda, S Miyauchi… - Proceedings of the …, 2003 - National Acad Sciences
Human capabilities in dexterously manipulating many different tools suggest modular neural
organization at functional levels, but anatomical modularity underlying the capabilities has …

Internal forward models in the cerebellum: fMRI study on grip force and load force coupling

M Kawato, T Kuroda, H Imamizu, E Nakano… - Progress in brain …, 2003 - Elsevier
Internal models are neural mechanisms that can mimic the input-output or output-input
properties of the motor apparatus and external objects. Forward internal models predict sensory …

[HTML][HTML] A small number of abnormal brain connections predicts adult autism spectrum disorder

…, M Kuroda, T Yamada, F Megumi, H Imamizu… - Nature …, 2016 - nature.com
Although autism spectrum disorder (ASD) is a serious lifelong condition, its underlying
neural mechanism remains unclear. Recently, neuroimaging-based classifiers for ASD and …

Consensus paper: the cerebellum's role in movement and cognition

…, N Andreasen, S D'Arrigo, S Bulgheroni, H Imamizu… - The Cerebellum, 2014 - Springer
While the cerebellum's role in motor function is well recognized, the nature of its concurrent
role in cognitive function remains considerably less clear. The current consensus paper …

Quantitative examinations of internal representations for arm trajectory planning: minimum commanded torque change model

E Nakano, H Imamizu, R Osu, Y Uno… - Journal of …, 1999 - journals.physiology.org
Hiroshi ImamizuHiroshi Imamizu … The actual beginning and end positions of each movement
were determined using a two-dimensional curvature with a 3-mm −1 threshold (Imamizu et …

A neural correlate of reward-based behavioral learning in caudate nucleus: a functional magnetic resonance imaging study of a stochastic decision task

…, M Kimura, K Samejima, H Imamizu… - Journal of …, 2004 - Soc Neuroscience
Humans can acquire appropriate behaviors that maximize rewards on a trial-and-error basis.
Recent electrophysiological and imaging studies have demonstrated that neural activity in …

Activation of the human superior temporal gyrus during observation of goal attribution by intentional objects

J Schultz, H Imamizu, M Kawato… - Journal of cognitive …, 2004 - direct.mit.edu
Previous functional imaging experiments in humans showed activation increases in the
posterior superior temporal gyrus and sulcus during observation of geometrical shapes whose …
