Scene perception allows humans to extract information from their environment and plan navigation efficiently. The automatic extraction of potential paths in a scene, also referred to as navigational affordance, is supported by scene-selective regions (SSRs) that enable efficient human navigation. Recent evidence suggests that the activity of...

Spatial navigation is an intricate ability, requiring multisensory and motor integration, that is particularly impacted in aging. The age-related decline in navigational capabilities is known to be associated with changes in brain regions such as the frontal, temporal, and cerebellar cortices. Age-related cerebellar differences in spatial...

Older adults have difficulties in navigating unfamiliar environments and updating their wayfinding behavior when faced with blocked routes. This decline in navigational capabilities has traditionally been ascribed to memory impairments and dysexecutive function, whereas the impact of visual aging has often been overlooked. The ability to...

Aging leads to a complex pattern of structural and functional changes, gradually affecting sensorimotor, perceptual, and cognitive processes. These multiscale changes can hinder older adults' interaction with their environment, progressively reducing their autonomy in performing tasks relevant to everyday life. Autonomy loss can further be...

Cognitive demands for postural control increase with aging and cognitive-motor interference (CMI) exists for a number of walking situations, especially with visuo-spatial cognitive tasks. Such interference also influences spatial learning abilities among older adults; however, this is rarely considered in research on aging in spatial...

Gaze is an excellent metric for understanding human attention. However, research on identifying gaze behaviors saccades, fixations, and smooth pursuits for example for large (i e more than one meter viewing distance), interactive 3D scenes with virtual reality headsets is still in its early stages. The understanding of gaze behaviors is...

In this preliminary study, we introduce the use of personalized high-density optodes montage for cerebellar fNIRS acquisitions. One subject performed left or right finger tapping tasks consecutively with fNIRS and fMRI. Conclusive ipsilateral cerebellar activations were observed in the fNIRS HRF and supported by strong clusters in the fMRI.

Towards an fMRI validation of our previous fNIRS-based explorations of cerebellar activity [Rocco et al. EMBC 2021], we introduce here a joint sequential fNIRS/fMRI study based on finger tapping that provides both finer time and space granularities for the assessment of BOLD effect in the cerebellum.

fNIRS and fMRI sequences were simultaneously recorded from the cerebellum and motor cortex during a motor task. Spatial and temporal concordance between modalities and various data processing pipelines were assessed. The results confirm high spatial and temporal correlation and highlight the necessity of using an ad-hoc pipeline for the...

Apathy is a pervasive clinical syndrome in neurocognitive disorders, characterized by a quantitative reduction in goal-directed behaviors. The brain structures involved in the physiopathology of apathy have also been connected to the brain structures involved in probabilistic reward learning in the exploration-exploitation dilemma. This dilemma...

We present the CREATTIVE3D dataset of human interaction and navigation at road crossings in virtual reality. The dataset has three main breakthroughs: (1) it is the largest dataset of human motion in fully-annotated scenarios (40 hours, 2.6 million poses), (2) it is captured in dynamic 3D scenes with multivariate-gaze, physiology, and...
