Speech and Brain Research Group (Prof. Kate Watkins) Department of Experimental Psychology University of Oxford Email: [email protected] INSTEP TRIAL: Investigating non-invasive brain stimulation to enhance fluency in people who stutter CUREC Ref. No.: R52173/RE001 Version 1.0 Date 15th September 2017 VOLUNTEERS NEEDED FOR SPEECH RESEARCH Researchers at the Department of Experimental Psychology University of Oxford are seeking healthy fluent speaking male participants for a study investigating stuttering. Volunteers should be male, aged 18-45 years, and native English speakers. You will be asked questions about your medical history to check your suitability for an MRI scan and brain stimulation. The study involves MRI scanning of the brain and vocal tract, and transcranial magnetic stimulation (TMS), which will take place during one or two visits to the OHBA Centre at the Warneford Hospital in Oxford. MRI gives very detailed pictures of structure and function. TMS is used here to measure the excitability of the brain areas involved in speech production. These methods are non-invasive and do not involve ionising radiation. We will reimburse volunteers for their time and cover reasonable travel expenses. If you are interested in participating in this study and/or would like further information, please contact the Speech and Brain Research Group on [email protected] [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group [email protected] Speech & Brain Research Group Research Group Research .

I am also interested in research questions that relate to this goal, such as how brain circuits for speech/language change over childhood, what factors explain individual diﬀerences in speech/ language performance, how speech/language learning can be improved, and what neural changes occur as a function of learning and training in the auditory-motor domain. To address my research questions, I use classical behavioural paradigms, as well as structural and functional magnetic resonance imaging.

These findings are consistent with the theory that altered language lateralization may be a cause or consequence of stuttering. Here, we re-examined these findings in a larger sample of PWS. Methods: We evaluated planum temporale asymmetry in structural MRI scans obtained from 67 PWS and 63 age-matched controls using: 1) manual measurements of the surface area; 2) voxel- based morphometry to automatically calculate grey matter density. We examined the influences of gender, age, and stuttering severity on planum temporale asymmetry. Results: The size of the planum temporale and its asymmetry were not different in PWS compared with Controls using either the manual or the automated method. Both groups showed a sig- nificant leftwards asymmetry on average (about one-third of PWS and Controls showed right- ward asymmetry).

Abstract 563.19 Summary Senior author: Kate E. Watkins, PhD (44-18) 6522-2581 University of Oxford [email protected] Oxford, United Kingdom People Who Stutter Show Abnormal Brain Activity When Reading and Listening Study suggests abnormalities exist in speech processing as well as production A new imaging study finds that people who stutter show abnormal brain activity even when reading or listening. The results suggest that individuals who stutter have impaired speech due to irregular brain circuits that affect several language processing areas — not just the ones for speech production. The research was presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. Stuttering affects about one in every 20 children; most grow out of it, but one in five continues to struggle. While the particular cause of stuttering is still unknown, previous studies showed reduced activity in brain areas associated with listening, and increased activity in areas involved in speech and movement. In the new study, researchers considered whether irregular activity would also be apparent when stuttering speakers silently read. “If those patterns are also abnormal, the differences could be considered typical of the stuttering brain and not just the result of the difficulties that people who stutter have with speech production,” said senior author Kate Watkins, PhD, of the University of Oxford. Using functional magnetic resonance imaging (fMRI), Watkins and her team compared the brain activity in 12 adults who stutter with 12 adults who do not. The researchers conducted the scans in three trials: in one, volunteers simply listened to sentences; in the second, they read sentences silently; in the third, they read sentences silently while another person read the same sentence aloud.

1 Speech movement variability in people who stutter: a 2 vocal-tract MRI study 3 4 5 6 Charlotte E. E. Wiltshire, Mark Chiew, Jennifer Chesters, Máiréad P. Healy & Kate E. Watkins 7 Wellcome Centre for Integrative Neuroimaging, Department of Experimental Psychology, 8 Radcliffe Observatory Quarter, University of Oxford, OX2 6GG, UK 9 10 [email protected] (corresponding author) 11 [email protected] 12 [email protected] 13 [email protected] 14 [email protected] 15 16 Declarations of interest: none 17 18 19 Abstract 20 21 Purpose: People who stutter (PWS) have more unstable speech motor systems than people 22 who are typically fluent (PWTF). Here, we used real-time MRI of the vocal tract to assess 23 variability and duration of movements of different articulators in PWS and PWTF during fluent 24 speech production. 25 Method: The vocal tracts of 28 adults with moderate to severe stuttering and 20 PWTF were 26 scanned using MRI while repeating simple and complex pseudowords. Mid-sagittal images of 27 the vocal tract from lips to larynx were reconstructed at 33.3 frames per second. For each 1 28 participant, we measured the variability and duration of movements across multiple 29 repetitions of the pseudowords in three selected articulators: the lips, tongue body, and velum. 30 Results: PWS showed significantly greater speech movement variability than PWTF during 31 fluent repetitions of pseudowords. The group difference was most evident for measurements 32 of lip aperture, as reported previously, but here we report that movements of the tongue body 33 and velum were also affected during the same utterances.

Modulation of Motor Excitability During Speech Perception: the Role of Broca’S Area
Modulation of Motor Excitability during Speech Perception: The Role of Broca’s Area Kate Watkins and Toma´ˇs Paus Abstract & Studies in both human and nonhuman primates indicate regions that modulate the excitability of the motor system that motor and premotor cortical regions participate in during speech perception. Our results show that during auditory and visual perception of actions. Previous studies, auditory speech perception, there is increased excitability of using transcranial magnetic stimulation (TMS), showed that motor system underlying speech production and that this perceiving visual and auditory speech increased the excitability increase is significantly correlated with activity in the posterior of the orofacial motor system during speech perception. Such part of the left inferior frontal gyrus (Broca’s area). We propose studies, however, cannot tell us which brain regions mediate that this area ‘‘primes’’ the motor system in response to heard this effect. In this study, we used the technique of combining speech even when no speech output is required and, as such, positron emission tomography with TMS to identify the brain operates at the interface of perception and action. & INTRODUCTION perceptions to phonetic gestures and that such a system The division between the brain regions involved in might be at the origin of the evolution of human speech action production and perception is becoming increas- (Rizzolatti & Arbib, 1998; Gallese et al., 1996). ingly blurred as evidence accumulates that in the In humans, transcranial magnetic stimulation (TMS) primate brain, motor and premotor regions also par- applied over the primary motor cortex has been used ticipate in action perception.

Watkins Department of Experimental Psychology, University of Oxford, Oxford, UK E-mail: [email protected] Brenda Milner—the renowned neuroscientist who changed our understanding of brain and behaviour—celebrates her 100th birthday this year on St Swithun’s Day: 15 July 2018. We have known Brenda for the past quarter of that century initially as postdocs at the Montreal Neurological Institute (the MNI or the ‘Neuro’) and latterly as colleagues and friends. In this arti- cle, we summarize the impact and legacy of Brenda’s work. Brenda’s early life and career have been well documented (Milner, 1998). She grew up in Manchester, England. Her father was the music critic of the Manchester Guardian and died when Brenda was 8 years old. Brenda’s mother, who died aged 95, endowed her with longevity, a love of lan- guages, and taught her French so she could advance at school. Brenda won a scholarship to study at Newnham College, Cambridge University, initially to read Mathematics. She claims to have realized quite quickly that she would not excel in that subject and, fortuitously, took the decision to switch to Psychology.
