Most neuroimaging techniques require the participant to remain still for reliable recordings be made. Optically pumped magnetometer (OPM) based magnetoencephalography (OP-MEG) however, is a technique which can used measure neural signals during large movement (approximately 1 m) within magnetically shielded room (MSR) (Boto et al., 2018; Seymour 2021). Nevertheless, environmental magnetic fields vary both spatially and temporally OPMs only operate limited field range, constrains movement....
Most people have strong left-brain lateralisation for language, with a minority showing right- or bilateral language representation. On some receptive tasks, however, appears to be reduced absent. This contrasting pattern raises the question of whether and how laterality may fractionate within individuals. Building on our prior work, we postulated (a) that there can dissociations in different components (b) these would more common left-handers. A subsidiary hypothesis was indices will...
Although there is consensus that the left hemisphere plays a critical role in language processing, some questions remain. Here we examine influence of overt versus covert speech production on lateralization, relationship between lateralization and behavioural measures performance strength across subcomponents language. The present study used functional transcranial Doppler sonography (fTCD) to investigate phonological semantic fluency during both word generation right-handed adults....
The assessment of active language lateralization in infants and toddlers is challenging. It requires an imaging tool that unintimidating, quick to setup, robust movement, addition engaging cognitively simple processing task. Functional Transcranial Doppler Ultrasound (fTCD) offers a suitable technique here we report on method elicit production young children. 34-second "What Box" trial presents animated face "searching" for object.

The effect of sensory experience on hemispheric specialisation for language production is not well understood. Children born deaf, including those who have cochlear implants, drastically different perceptual experiences than their hearing peers. Using functional transcranial Doppler sonography (fTCD), we measured lateralisation during in a heterogeneous group 19 deaf children and children, matched ability. In observed significant left (British Sign Language, spoken English, or combination...
Studies to date that have used fTCD examine language lateralisation predominantly word or sentence generation tasks.Here we sought further assess the sensitivity of by using a metalinguistic task which does not involve novel speech generation: rhyme judgement in response written words.Line array was included as non-linguistic visuospatial relative strength left and right hemisphere within same individuals when output requirements tasks are matched.These externally paced allowed us manipulate...
Neuroimaging studies suggest greater involvement of the left parietal lobe in sign language compared to speech production. This stronger activation might be linked specific demands encoding and proprioceptive monitoring. In Experiment 1 we investigate hemispheric lateralization during generation hearing native users English British Sign Language (BSL). Participants exhibited BSL than 2 investigated whether this increased index could due exclusively higher motoric naïve participants performed...
The neural systems supporting speech and sign processing are very similar, although not identical. In a previous fTCD study of hearing native signers (Gutierrez-Sigut, Daws, et al., 2015) we found stronger left lateralization for than speech. Given that this increased could be explained by hand movement alone, the contribution motor versus 'linguistic' processes to strength hemispheric during production remains unclear. Here directly contrast covert overt signing phonological semantic...
Background: Lateralised representation of language in monolinguals is a well-established finding, but the situation much less clear when there more than one language. Studies to date have identified number factors that might influence brain organisation bilinguals. These include proficiency, age acquisition and exposure second The question as whether cerebral lateralisation first languages are same or different yet unresolved. Methods: We used functional transcranial Doppler sonography...
