Understand what happens in the brains of individuals experiencing psychosis related language difficulties down to a millisecond precision.
00:00:10.383 --> 00:00:19.383
Hi, I am Hsi Tiana Wei, a postdoctoral researcher at McGill University and Douglas Mental Health Institute, and I'm excited to share with you what we found.
00:00:20.583 --> 00:00:26.583
Schizophrenic patients struggle with daily communication in the form of flattened affect.
00:00:26.483 --> 00:00:34.483
Reduced and disorganized speech. To study speech, which is such a dynamic behavioral symptom.
00:00:34.418 --> 00:00:43.418
MEG is an excellent neuroimaging tool that allows us to record high precision of spatial temporal, spectral.
00:00:43.833 --> 00:00:51.833
And network level connectivity information. And these are all neuronal aspects that have shown deviations in schizophrenic patients.
00:00:53.083 --> 00:01:04.083
And importantly, without understanding the associations between these deviated neural dynamics with communicative symptoms and clinical symptoms in schizophrenic patients.
00:01:04.618 --> 00:01:16.618
The development of treatments focusing on neurochemical alterations using drugs or neural oscillatory modulations using non-invasive brain stimulations would be considerably limited.
00:01:17.283 --> 00:01:29.283
So to improve the understanding of these associations, the current study that we ran, recruiting We are recruiting 25 schizophrenic patients and 25 healthy controls.
00:01:29.383 --> 00:01:39.383
For three main domains of data. Including one session of MEG recording during a sensorimotor task so that we can characterize their neural dynamic.
00:01:39.921 --> 00:01:47.921
And a natural speech task where we will extract the linguistic and acoustic features using large language models.
00:01:47.384 --> 00:02:02.384
And a battery of clinical assessments. This is a rich data set that allowed us to look into the associations and interactions between neural dynamics, speech, and clinical symptoms in our patients and control groups.
00:02:02.333 --> 00:02:07.333
So we're not only looking at factors and features that differentiate patients from control.
00:02:07.833 --> 00:02:18.833
We're also looking into individual differences within each population group. So come to my presentation on April 1st at 5 p.m. In Regency Ballroom C.
00:02:18.979 --> 00:02:26.979
To hear more about what we found and discuss how this study can inform the development of neuromodulatory treatments for psychosis. Looking forward to seeing you there.
