Cambridge Brain MRI meeting schedule
Aims
The Cambridge Brain MRI meetings are intended to provide a forum for discussion and to facilitate new collaborations for anyone interested in magnetic resonance imaging or magnetic resonance spectroscopy in the brain. The meetings run from 3-5pm four times per year. Topics discussed include work on human brain imaging, animal imaging, and ex vivo or phantom imaging. We normally have one external invited speaker per session, followed by a series of presentations from researchers at Cambridge, particularly with a focus on those working at the postdoctoral / young principal investigator level. We often also have a "Data Blitz" which is an opportunity for anyone who wishes to present for 1 minute (exactly!!) with one slide. This is a great opportunity to advertise the availability of a new method, or to seek collaborators for a new project, or to showcase a piece of recently completed work.
Organisers
The Cambridge Brain MRI meetings are organised as a service to the Cambridge MRI/MRS community by Hugh Markus (on sabbatical), Chris Rodgers, Zoe Kourtzi (on sabbatical), Rik Henson and Tom Cope. Please do not hesitate to contact us if you would like to speak, have suggestions for future meetings, or other feedback on things you like or constructive comments on things that are not good.
Next Meeting
20 Nov 2019: Meeting #8
Dear Colleagues,
The eighth Cambridge Brain MRI Meeting will be held on Wednesday 20th Nov 2019 at 15.00 - 17.00. The meeting will be in the Herchel Smith Ground Floor Seminar Room, Forvie Site, Robinson Way, (https://goo.gl/oYgMtp).
We are delighted to welcome Lars Muckli from Glasgow and Shaihan Malik from London as external speakers, and Zhongzhao Teng from Cambridge.
Programme
Chair: TBC
15.00-15.40 Lars Muckli, Glasgow : Visual Predictions in different layers of visual cortex
Normal brain function involves the interaction of internal processes with incoming sensory stimuli. We have created a series of brain imaging experiments that sample internal models and feedback mechanisms in early visual cortex. Primary visual cortex (V1) is the entry-stage for cortical processing of visual information. We can show that there are two information counter-streams concerned with: (1) retinotopic visual input and (2) top-down predictions of internal models generated by the brain. Our results speak to the conceptual framework of predictive coding. Internal models amplify and disamplify incoming information. The brain is a prediction-machinery. Healthy brain function will strike a balance between precision of prediction and prediction update based on prediction error. Our results incorporate state of the art, layer-specific ultra-high field fMRI and other imaging techniques. We argue that fMRI with it’s capability of measuring dendritic energy consumption is sensitive to record activity in different parts of layer spanning neurons which enriches our computational understanding of counter stream brain mechanisms.
15.40.16.20 Shaihan Malik, King's College London : Parallel transmit MRI for improved data quality at (ultra)high field
In the last ten years parallel RF transmit (pTx) technology has become integrated into clinical MRI systems and is now a mainstay of 7T systems in particular. By introducing additional degrees of freedom to control the RF fields produced within the scanner, pTx offers the ability to improve uniformity of signal and contrast, and to make scanning more efficient. However use of pTx is not always straightforward, and there are different levels at which the technology can be used to interact with the pulse sequence being used. In this talk I will review the scope of how pTx could be used to enhance brain imaging at (ultra)high field and discuss some of the methods developed at KCL on both 3T and 7T systems.
16.20-16.40 Zhongzhao Teng, Dept of Radiology, Cambridge

Previous Meetings
18 Sep 2019: Meeting #7
The seventh Cambridge Brain MRI Meeting was on Wednesday 18th Sep 2019 at 15.00 - 17.00.
Programme
15.00-15.40 Emrah Duzel, DZNE
Emrah is Site Speaker and Head of Clinical Research of the site Magdeburg. His research centres around studying memory problems in Alzheimer's patients and healthy older people. These problems are an early symptom of Alzheimer's disease (AD) but they also often occur in healthy older people. Experimental and clinical data shows that cognitive and physical training can improve the memory function of healthy older people and might also improve the memory function in the early stage of AD.However, the specific prerequisites, neurobiological modes of action, and clinical conditions of training-dependent improvements have not been systematically studied yet.
