Накратко на български

Функционалната организация на мозъка се изследва, за да се разбере дали едни и същи зони обработват движението, независимо дали то е визуално, слухово или се усеща чрез допир. Резултатите ще помогнат при разработването на програми за рехабилитация след загуба на сетивно възприятие.

Functional organization of the multisensory motion system

One of the most significant current discussions in the understanding of the human brain is the functional recruitment of some regions of the cortex for specific tasks, regardless the sensory modality (e.g. visual, tactile or auditory) in which the stimuli is received. The ability to perceive motion, among others visual properties, is a fundamental faculty of the human brain. Brain lesions that impair the detection and processing of motion have a profound impact on daily activity. Consequently, visual motion processing is one of the most fundamental and well-studied systems in the human brain, canonically known to develop mainly for the purpose of visual perception. A great deal of study on the multisensory responses to motion processing in the human brain focused on the middle temporal complex and superior temporal sulcus. Several studies using both neurophysiological and neuroimaging techniques showed the multisensory properties of these areas, showing their recruitment during both tactile and auditory motion stimulation. Despite the large amount of study on the topic it is still unclear whether the recruitment of these areas directly mediates the perception of motion through the different sensory input or regulates responses within primary sensory areas involved in the task. The outcome of this MSCA will inspire novel research lines on how the brain reorganize in case of a sensory loss and on clinical applications such as rehabilitation programs that aim at restoring function through other sensory modalities.

Цел на проекта

One of the most significant current discussions in the understanding of the human brain is the functional recruitment of some regions of the cortex for specific tasks, regardless the sensory modality (e.g. visual, tactile or auditory) in which the stimuli is received. The ability to perceive motion, among others visual properties, is a fundamental faculty of the human brain. The predisposition to detect motion is present since the first months of life and is one of the main prerequisites for a child’s healthy brain development. Brain lesions that impair the detection and processing of motion have a profound impact on daily activity. Consequently, visual motion processing is one of the most fundamental and well-studied systems in the human brain, canonically known to develop mainly for the purpose of visual perception. The aim of this proposal is to elucidate in humans whether the functional recruitment and specialization of the visual motion system is independent of the sensory modality in which the stimuli are perceived, to characterize the sensory independent functional mesoscopic architecture within the brain regions involved and to establish their causal role in perception. I will answer these questions using advanced methods such as ultra-high field fMRI at 7T, intracranial electrodes, transcranial magnetic stimulation and advanced neural based analyses. The integrated approach I propose here provides a unique multiangle perspective to investigate the neural substrate of multisensory processes. The fact that motion sensitive brain regions exhibit sensory-independent responses and that the same neuronal ensemble may respond to aspecific sensory features will challenge our notions on brain sensory segregation and functional development and will impact other high-level cognition studies at large. Moreover, it will provide essential knowledge for novel research on sensory substitution devices for rehabilitation in sensory-impaired individuals.
