Fukushima K, Fukushima J, Barnes G
Exp Brain Res
. 2017 Mar;
235(5):1309-1321.
PMID: 28258438
Parkinson's disease (PD) is a progressive neurodegenerative disorder of the basal ganglia. Most PD patients suffer from somatomotor and oculomotor disorders. The oculomotor system facilitates obtaining accurate information from the...

Fukushima K, Ito N, Barnes G, Onishi S, Kobayashi N, Takei H, et al.
Physiol Rep
. 2015 Apr;
3(3).
PMID: 25825544
While retinal image motion is the primary input for smooth-pursuit, its efficiency depends on cognitive processes including prediction. Reports are conflicting on impaired prediction during pursuit in Parkinson's disease. By...

Fukushima K, Barnes G, Ito N, Olley P, Warabi T
Exp Brain Res
. 2014 Apr;
232(7):2369-79.
PMID: 24736861
Aging affects virtually all functions including sensory/motor and cognitive activities. While retinal image motion is the primary input for smooth-pursuit, its efficiency/accuracy depends on cognitive processes. Elderly subjects exhibit gain...

Burke M, Barnes G
PLoS One
. 2013 Sep;
8(9):e73326.
PMID: 24039911
How the brain stores motion information and subsequently uses it to follow a moving target is largely unknown. This is mainly due to previous fMRI studies using paradigms in which...

Ito N, Barnes G, Fukushima J, Fukushima K, Warabi T
Exp Brain Res
. 2013 Jun;
229(1):23-35.
PMID: 23736523
Using a cue-dependent memory-based smooth-pursuit task previously applied to monkeys, we examined the effects of visual motion-memory on smooth-pursuit eye movements in normal human subjects and compared the results with...

Fukushima K, Fukushima J, Warabi T, Barnes G
Front Syst Neurosci
. 2013 Mar;
7:4.
PMID: 23515488
Smooth-pursuit eye movements allow primates to track moving objects. Efficient pursuit requires appropriate target selection and predictive compensation for inherent processing delays. Prediction depends on expectation of future object motion,...

Bennett S, ODonnell D, Hansen S, Barnes G
J Vis
. 2012 Dec;
12(13):17.
PMID: 23262149
Smooth pursuit during prolonged occlusion is improved in the presence of sensorimotor signals when tracking self-generated target motion. The current study investigated whether concurrent arm tracking of externally-generated target motion...

Barnes G, Collins C
Exp Brain Res
. 2011 May;
212(2):225-40.
PMID: 21590260
When humans pursue motion stimuli composed of alternating constant velocity segments of randomised duration (RD), they nevertheless initiate anticipatory eye deceleration before stimulus direction changes at a pre-programmed time based...

Burke M, Barnes G
J Cogn Neurosci
. 2011 Apr;
23(11):3294-303.
PMID: 21452936
A previous study has shown that actively pursuing a moving target provides a predictive motor advantage when compared with passive observation of the moving target while keeping the eyes still...

Ackerley R, Barnes G
J Physiol
. 2011 Feb;
589(Pt 7):1627-42.
PMID: 21300755
The ability to co-ordinate the eyes and head when tracking moving objects is important for survival. Tracking with eyes alone is controlled by both visually dependent and extra-retinal mechanisms, the...
