The role of visual salience in directing eye movements in visual object agnosia. by Mannan, S, Kennard, C, Husain, M

Eye movements in visual search indicate impaired saliency processing in Parkinson's disease. by Mannan, S, Hodgson, T, Husain, M, Kennard, C

“…Previous studies have produced contradictory evidence on the nature of the visual search impairment in patients with Parkinson's disease (PD). Eye movements were measured during multi-target search in nine individuals with mild-to-moderate PD. …”

Compensatory strategies following visual search training in patients with homonymous hemianopia: an eye movement study. by Mannan, S, Pambakian, A, Kennard, C

“…Taken together these results suggest that visual training facilitates the development of specific compensatory eye movement strategies in patients with homonymous visual field defects.…”

Eye movements discriminate fatigue due to chronotypical factors and time spent on task--a double dissociation by Cazzoli, D, Antoniades, C, Kennard, C, Nyffeler, T, Bassetti, C, Müri, R

“…However, eye movements have not been used so far to investigate the circadian synchronicity effect and the resulting differences in fatigue. …”

Disorders of higher gaze control. by Kennard, C

“…The neural centers in the cerebral hemispheres, both cortex and basal ganglia, involved in the generation of saccadic and smooth pursuit eye movements have been well delineated in terms of their location and function. …”

Pallidal Deep Brain Stimulation Improves Higher Control of the Oculomotor System in Parkinson's Disease by Antoniades, CA, Rebelo, P, Kennard, C, Aziz, TZ, Green, AL, Fitzgerald, JJ

“…Our aim was to compare the effects of STN DBS and GPi DBS on the AER. We tested eye movements in 14 human DBS patients and 10 controls. …”

The role of the ventrolateral frontal cortex in inhibitory oculomotor control. by Hodgson, T, Chamberlain, M, Parris, B, James, M, Gutowski, N, Husain, M, Kennard, C

“…However, the contribution of this region to the control of eye movements has not been clearly established. Here, we describe the performance of a group of 23 frontal lobe damaged patients in an oculomotor rule switching task for which the association between a centrally presented visual cue and the direction of a saccade could change from trial to trial. …”

Generalisation of new sequence knowledge depends on response modality by Rosenthal, C, Ng, T, Kennard, C

“…Here, we examined whether learning a visuospatial sequence either via manual (key presses, without eye movements), oculomotor (obligatory eye movements), or perceptual (covert reorienting of visuospatial attention) responses supported generalisation to direct and indirect tests administered either in the same (baseline conditions) or a novel response modality (transfer conditions) with respect to initial study. …”

Oculomotor Dysfunction in Parkinson's Disease by Kennard, C, Nachev, P

“…In this chapter, we shall give a brief overview of the anatomy and physiology of eye movements before proceeding to a detailed examination of the oculomotor abnormalities in patients with PD. © Springer Science+Business Media New York 2013.…”

The neuro-ophthalmological examination. by Rucker, J, Kennard, C, Leigh, R

“…Covered examination topics include visual acuity, visual field testing, color vision, external eye exam, pupils, ophthalmoscopy, and eye movements. The final section discusses ancillary tests that supplement the bedside neuro-ophthalmological examination, including formal visual field analysis, electroretinography, fluorescein angiography, ocular coherence tomography, visual-evoked potentials, neuroimaging, and quantitative eye movement recordings.…”

Revisiting previously searched locations in visual neglect: role of right parietal and frontal lesions in misjudging old locations as new. by Mannan, S, Mort, D, Hodgson, T, Driver, J, Kennard, C, Husain, M

“…Here, we not only tracked the eye movements of 16 neglect patients during search, but also asked them to click a response button only when they judged they were fixating a target for the very first time. …”

Cognitive processes in saccade generation. by Kennard, C, Mannan, S, Nachev, P, Parton, A, Mort, D, Rees, G, Hodgson, T, Husain, M

“…A series of studies in a patient with a focal lesion of the right SEF has indicated an important role for the SEF in the rapid self-control of saccadic eye movements and in set-switching (i.e., implementing control in situations of response conflict when ongoing saccadic plans have to be changed rapidly), rather than monitoring errors. …”

Learning and switching between stimulus-saccade associations in Parkinson's disease. by Hodgson, T, Sumner, P, Molyva, D, Sheridan, R, Kennard, C

“…Previous work in patients with focal lesions has shown that the control of saccadic eye movements in such contexts relies on a network of areas in the frontal cerebral cortex. …”

A comparison of change blindness in real-world and on-screen viewing of museum artefacts by Attwood, J, Kennard, C, Harris, J, Humphreys, G, Antoniades, C

“…We discuss possible implications of these results for understanding change blindness, such as the role of binocular vs. monocular vision and that of head and eye movements, as well as reflecting on the evolution of change detection systems, and the impact of the experimental design itself on our results. …”

Magnetic oculomotor prosthetics for acquired nystagmus by Nachev, P, Rose, GE, Verity, DH, Manohar, SG, MacKenzie, K, Adams, G, Theodorou, M, Pankhurst, QA, Kennard, C

“…These improvements were maintained throughout a follow-up of 4 years and enabled him to return to paid employment.This work opens a new field of implantable therapeutic devices-oculomotor prosthetics-designed to modify eye movements dynamically by physical means in cases where a purely neural approach is ineffective. …”

Ocular motor abnormalities in neurodegenerative disorders. by Antoniades, C, Kennard, C

“…Eye movements are a source of valuable information to both clinicians and scientists as abnormalities of them frequently act as clues to the localization of a disease process. …”

Distinct cortical and collicular mechanisms of inhibition of return revealed with S cone stimuli. by Sumner, P, Nachev, P, Vora, N, Husain, M, Kennard, C

“…Critically, however, we found that S cone stimuli did not cause IOR when saccadic eye movement responses were required. This demonstrates that saccadic IOR is not the same as traditional IOR, providing support for two separate cortical and collicular mechanisms of IOR. …”
