Objective To explore the lived experiences and extent of cognitive symptoms in Long COVID (LC) a UK-based sample. Design This study implemented mixed-methods design. Eight focus groups were conducted to collect qualitative data, Framework Analysis was used reveal impact symptoms. A self-report questionnaire quantitative data assess perceived change symptomology post COVID-19. Setting Focus April 2023 online via Zoom in-person at University Leeds, UK. Participants 25 people with LC living UK...

Recent electrophysiological and behavioral studies have found similarities in the neurology of pursuit saccadic eye movements. In a previous study on movements using closely matched paradigms for saccades, we revealed that both exhibit bimodal distributions latency to predictable (PRD) randomized (RND) stimuli; however, each type stimulus was different, there more segregation latencies saccades than (Burke MR, Barnes GR. 2006. Quantitative differences smooth humans. Exp Brain Res....

Abstract Introduction This study investigated the validity of two brief cognitive tests (Memory Alteration Test [M@T] and Your Memory [TYM] test) for identifying people with aMCI in community. Methods Older were invited to participate by their general practitioner practice. Eligible participants assessed using an operationalized approach Petersen criteria M@T TYM. Results Both demonstrated significant ability discriminating between controls (AUC = 0.91 0.80 TYM [ P < .001 both])....

The corpus callosum (CC) is the largest bundle of white matter tracts in brain connecting left and right cerebral hemispheres. posterior region CC, known as splenium, seems to be relatively preserved throughout lifespan regularly examined for indications various pathologies, including Alzheimer's disease (AD) Mild Cognitive Impairment (MCI). However, splenium has rarely been investigated terms its distinct inter-hemispheric tract bundles that project bilateral occipital, parietal temporal...

Sequence learning is common to all motor systems and an essential aspect of human behavior necessary for the acquisition skill. Many previous studies have demonstrated ability observe, store, repeat sequences in a variety modalities resulting reduced reaction time. Recently, it has been found that subjects can make predictive smooth eye movements sequence discrete horizontal target motions (C. J. Collins & Barnes, 2005). The present study extends paradigm into two dimensions motion order...

Objectives To identify the needs of people with long COVID (LC) in UK. Design Qualitative study using Framework Analysis to analyse focus group discussions. Participants 25 adults LC aged 19–76 years including 17 men and 8 women. Average disease duration was 80.1 weeks. Setting Eight groups were conducted April 2023 online in-person at University Leeds (UoL), Recruitment routes included advertisement via Community Healthcare services, English National Opera Breathe Programme within UoL....

The ability to use advance information prepare and execute a movement requires cognitive control of behaviour (e.g., anticipation inhibition). Our aim was explore the integrity saccadic eye in developmental coordination disorder (DCD) typically developing (TD) children (8-12 years) assess how these plan inhibit responses, principal mechanisms within visual attention control. Eye movements touch responses were measured (separately concurrently) Cued Non-Cued conditions. We found that with DCD...

Healthy aging is associated with a decline in visuospatial working memory. The nature of the changes leading to this response eye and/or hand still under debate. This study aims establish whether impairments observed performance on cognitive tasks are due actual effects or caused by motor-related eye-hand coordination.We implemented computerized version Corsi span task. and touch responses healthy young older adults were recorded series remembered targets screen.Results revealed differences...

A previous study has shown that actively pursuing a moving target provides predictive motor advantage when compared with passive observation of the while keeping eyes still [Burke, M. R., & Barnes, G. R. Anticipatory eye movements evoked after active following versus predictable motion stimulus. Brain Research, 15, 74-81, 2008b]. By using novel paradigm based on combining smooth pursuit stimulus go/no-go task, we have been able to reveal significant differences in brain activity for...

Recent behavioural and biological evidence indicates common mechanisms serving working memory attention (eg Awh et al, 2006 Neuroscience139 201–208). This study explored the role of spatial visual search in an adapted Corsi task. Eye movements touch responses were recorded from participants who recalled locations (signalled by colour or shape change) array presented either simultaneously sequentially. The time delay between target presentation recall (0,5, 10 s) number to be remembered (2–5)...
