Sensory prediction errors drive cerebellum-dependent adaptation of reaching

…, R Shadmehr, AJ Bastian - Journal of …, 2007 - journals.physiology.org
The cerebellum is an essential part of the neural network involved in adapting goal-directed
arm movements. This adaptation might rely on two distinct signals: a sensory prediction …

Throwing while looking through prisms: I. Focal olivocerebellar lesions impair adaptation

TA Martin, JG Keating, HP Goodkin, AJ Bastian… - Brain, 1996 - academic.oup.com
Normal human subjects and patients with lesions of the olivocerebellar system threw balls of
clay at a visual target while wearing wedge prism spectacles. Normal subjects initially threw …

Learning to predict the future: the cerebellum adapts feedforward movement control

AJ Bastian - Current opinion in neurobiology, 2006 - Elsevier
The role of the cerebellum in motor control and learning has been largely inferred from the
effects of cerebellar damage. Recent work shows that cerebellar damage produces greater …

Cerebellar ataxia: abnormal control of interaction torques across multiple joints

AJ Bastian, TA Martin, JG Keating… - Journal of …, 1996 - journals.physiology.org
1. We studied seven subjects with cerebellar lesions and seven control subjects as they
made reaching movements in the sagittal plane to a target directly in front of them. Reaches …

Cerebellar contributions to locomotor adaptations during splitbelt treadmill walking

SM Morton, AJ Bastian - Journal of Neuroscience, 2006 - Soc Neuroscience
Locomotor adaptability ranges from the simple and fast-acting to the complex and long-lasting
and is a requirement for successful mobility in an unpredictable environment. Several …

Interlimb coordination during locomotion: what can be adapted and stored?

…, HJ Block, AJ Bastian - Journal of …, 2005 - journals.physiology.org
Interlimb coordination is critically important during bipedal locomotion and often must be
adapted to account for varying environmental circumstances. Here we studied adaptation of …

Locomotor adaptation on a split-belt treadmill can improve walking symmetry post-stroke

DS Reisman, R Wityk, K Silver, AJ Bastian - Brain, 2007 - academic.oup.com
Human locomotion must be flexible in order to meet varied environmental demands. Alterations
to the gait pattern occur on different time scales, ranging from fast, reactive adjustments …

Cerebellar control of balance and locomotion

SM Morton, AJ Bastian - The neuroscientist, 2004 - journals.sagepub.com
The cerebellum is important for movement control and plays a particularly crucial role in
balance and locomotion. As such, one of the most characteristic signs of cerebellar damage is …

Throwing while looking through prisms: II. Specificity and storage of multiple gaze—throw calibrations

TA Martin, JG Keating, HP Goodkin, AJ Bastian… - Brain, 1996 - academic.oup.com
Human subjects threw balls of clay at a visual target while looking through wedge prism
spectacles. In studies of short-term adjustment, subjects threw in the direction of their prism-bent …

Understanding sensorimotor adaptation and learning for rehabilitation

AJ Bastian - Current opinion in neurology, 2008 - journals.lww.com
Adaptation is inherently important for rehabilitation by making movement flexible, but can
also be used to ascertain whether some patients can generate a more normal motor pattern. …
