10:20 Towards Increased Precision, Interpretability, and Impact: The Future of fMRI
ABSTRACT
Since its inception over 30 years ago, fMRI has catalyzed neuroscience research, showing a steady progression in precision, interpretability, and applicability due to improvements in acquisition and processing methods, as well as increased integration with other modalities that have helped establish the relationship between the fMRI signal and other measures, including behavior. In this lecture, I will first present a perspective of fMRI, highlighting its most significant advances and impact on neuroscience. I will then present work from my lab highlighting our approaches to advancing spatial and temporal precision and interpretability. I will highlight several of our studies showing a) whole-brain, ultra-high resolution, cortical depth resolved fMRI, b) insights into resting state fluctuations, c) approaches to increasing temporal precision of fMRI. Finally, I will speculate on the potential future impact of fMRI, highlighting current directions.

11:00 Computational Diffusion MRI for Microstructure Imaging
ABSTRACT
Magnetic Resonance (MR) imaging is the gold standard for both functional and structural studies of the human brain. Diffusion MR imaging enables the measurement of water diffusion properties in each voxel of a volume, making it highly sensitive to the characteristics of the underlying tissue. Diffusion-based microstructural imaging aims to estimate tissue microstructural properties, such as cell size and density, by analyzing the diffusion MR signal from each voxel. In this presentation, we will introduce the computational framework we have developed to estimate tissue microstructural properties from diffusion MRI data. This framework encompasses signal modeling, diffusion MRI protocol design, in-silico realistic diffusion simulations, and inverse model estimation. Applications in brain imaging and oncology will also be discussed.

11:30 Treatment Planning and Disease Subtyping with Imaging for Precision Medicine
ABSTRACT
Precision medicine approaches aim to improve patient care by focusing therapies on specific subgroups of patients. They rely on precise characterisation of patients and disease by using different technologies, including genomic analysis and imaging. Within the imaging context, precision medicine leads to ever-increasing demand for imaging procedures, improved image quality, and types of images. While patient outcomes can be measurably improved, the richness of the data also comes with heavier workloads for medical professionals. Automation approaches, mainly based on classical and deep machine learning, have emerged as a potential solution to this data deluge. The first part of the talk will focus on acute stroke, showing how imaging protocol changes can affect critical estimates of infarct volume obtained with clinical standard approaches, and potentially lead to different treatment options with severe consequences. Robustness of deep learning models for the same task will be discussed. The second part of the talk will focus on subtying of heart failure patients, and how imaging genetics of cardiac function measured through MRI offers a promising way to uncover disease pathways and potential drug targets.

13:00 Translational Neuromodeling, Computational Psychiatry and Computational Psychosomatics
ABSTRACT
For many brain diseases, particularly in psychiatry and psychosomatic medicine, we lack clinical tests for detecting individual disease mechanisms and cannot predict optimal treatment for individual patients. Over the last two decades, computational approaches to addressing these problems have gained traction. In this presentation, I summarise work that spans (i) the construction of computational theories of mental disorders, (ii) the development of computational assays for neuroimaging and behavioural data that target mechanisms proposed by these theories, and (iii) the application to concrete clinical problems.

13:30 Exploring Parallel-Transmit (pTx) MRI Applications with Multi-nuclei RF Coil Design, Multi-modal Imaging and RF Safety for Implanted Electrodes
ABSTRACT
The talk will address the stages of RF coil design from conceptualization into prototyping and finally validation concepts covering imaging of multiple nuclei in human body. The examples will cover some of 7T MRI RF coil array prototypes she worked on so far. Then, it will raise some solutions for simultaneous scalp electroencephalogram (EEG)-MRI at 7T to record good quality EEG data and MRI image. At 7T, parallel-transmit (pTx) is required to extend the field -of-view of the image with better homogeneity and efficiency. In addition, pTx allows steering of RF amplitude and phase of the signal by independently controllable RF coils and to design excitations that induce minimal RF currents in surrounded or implanted conductors in tissues. The investigations of the RF current mitigation methods on implants with pTx will be shown for clinical MRI scanners.

14:00 Neurometabolic Links Between Anxiety and Motivation
ABSTRACT
The interplay between brain mitochondria and metabolism and, on the other hand, the regulation of anxiety and motivation represents a cutting-edge frontier in psychiatric neuroscience, challenging the conventional understanding of the etiology and management of these intricate emotional disorders. Emphasizing corticostriatal pathways, this talk aims to uncover the intricate relationships between mitochondria, metabolism, and neural circuitry in modulating behaviors associated with anxiety and depression (i.e., low motivation). Through diverse experimental approaches in both rodent models and human studies employing magnetic resonance spectroscopy (MRS) and functional magnetic resonance imaging (fMRI), our research sheds light on novel pathways and mechanisms underlying the pathophysiology of these conditions, highlighting potential targets for therapeutic intervention. Specifically, our findings reveal the significant role of mitochondrial function and metabolism across the nucleus accumbens and the dorsomedial prefrontal cortex/dorsal anterior cingulate (dmPFC/dACC). Additionally, we explore the impact of key hormonal systems on the functioning of the nucleus accumbens and motivated behavior, elucidating anxiety-related differences. Our work uncovers novel insights into the pathophysiology of anxiety and depression, paving the way for innovative therapeutic strategies.

14:30 Brain Networks and Multimodality: Building on 100 Years of EEG
ABSTRACT
EEG is a versatile technique, that allows recording brain activity non-invasively in a wide range of contexts: from well controlled lab conditions, including freely moving subjects, to hospital bedsides including in intensive care and surgical theaters. Intracranial EEG offer sensitive and specific recordings of brain activity, from cortical patches to single neurons. Multimodal and multiscale recordings or post-processing combination allow to investigate complex relationships between single neurons and scalp signals as well as brain structure and function. This talk will highlight some recent methodological developments and applications and present some perspectives and challenges for the integration of these advances into clinical practice.
