A mechanical device for precise self-administration of ocular drugs Open
Individuals with glaucoma are routinely prescribed and required to self-administer eye drop-based medication multiple times a day. Unfortunately, the process of self-administering eye drops requires a level of dexterity, strength, and visu…

Digital wearable insole-based identification of knee arthropathies and gait signatures using machine learning Open
Gait is impaired in musculoskeletal conditions, such as knee arthropathy. Gait analysis is used in clinical practice to inform diagnosis and monitor disease progression or intervention response. However, clinical gait analysis relies on su…

Visual perception of highly memorable images is mediated by a distributed network of ventral visual regions that enable a late memorability response Open
Behavioral and neuroscience studies in humans and primates have shown that memorability is an intrinsic property of an image that predicts its strength of encoding into and retrieval from memory. While previous work has independently probe…

Theta-phase-specific modulation of dentate gyrus memory neurons Open
The theta rhythm, a quasi-periodic 4–10 Hz oscillation, is observed during memory processing in the hippocampus, with different phases of theta hypothesized to separate independent streams of information related to the encoding and recall …

BOLD Moments: modeling short visual events through a video fMRI dataset and metadata Open
Studying the neural basis of human dynamic visual perception requires extensive experimental data to evaluate the large swathes of functionally diverse brain neural networks driven by perceiving visual events. Here, we introduce the BOLD M…

Machine learning analysis of a digital insole versus clinical standard gait assessments for digital endpoint development Open
Biomechanical gait analysis informs clinical practice and research by linking characteristics of gait with neurological or musculoskeletal injury or disease. However, there are limitations to analyses conducted at gait labs as they require…

Cochlea to categories: The spatiotemporal dynamics of semantic auditory representations Open
How does the auditory system categorize natural sounds? Here we apply multimodal neuroimaging to illustrate the progression from acoustic to semantically dominated representations. Combining magnetoencephalographic (MEG) and functional mag…

The Algonauts Project 2021 Challenge: How the Human Brain Makes Sense of a World in Motion Open
The sciences of natural and artificial intelligence are fundamentally connected. Brain-inspired human-engineered AI are now the standard for predicting human brain responses during vision, and conversely, the brain continues to inspire inv…

Spatiotemporal Dynamics of Sound Representations reveal a Hierarchical Progression of Category Selectivity Open
As the human brain transforms incoming sounds, it remains unclear whether semantic meaning is assigned via distributed, domain-general architectures or specialized hierarchical streams. Here we show that the spatiotemporal progression from…

Emergence of Visual Center-Periphery Spatial Organization in Deep Convolutional Neural Networks Open
Research at the intersection of computer vision and neuroscience has revealed hierarchical correspondence between layers of deep convolutional neural networks (DCNNs) and cascade of regions along human ventral visual cortex. Recently, stud…

Neural Dynamics of Category Representations Across Space and Time in the Ventral Visual Cortex Open
Previous neuroscience works have established a functional organization across ventral visual stream such that distinct categories are processed in different brain areas; e.g. the parahippocampal cortex (PHC) for places, the object-selectiv…

Spatiotemporal neural representations in high-level visual cortex evoked from sounds Open
It is well established that areas of high-level visual cortex are selectively driven by visual categories such as places, objects, and faces. These areas include the scene-selective parahippocampal place area (PPA), occipital place area (O…

Assessing Reproducibility of MEG and fMRI Data Fusion Method in Neural Dynamics of Object Vision Open
Visual object recognition arises from a series of spatio-temporal activity patterns within the ventral and dorsal streams. To reveal human brain neural dynamics, Cichy et al. (2014, 2016) integrated measurements of functional magnetic reso…
