Spatial reasoning via recurrent neural dynamics in mouse retrosplenial cortex.

Nature neuroscience Jun 6, 2025
From visual perception to language, sensory stimuli change their meaning depending on previous experience. Recurrent neural dynamics can interpret stimuli based on externally cued context, but it is unknown whether they can compute and employ interna...

Egocentric value maps of the near-body environment.

Nature neuroscience Jun 2, 2025
Body-part-centered response fields are pervasive in single neurons, functional magnetic resonance imaging, electroencephalography and behavior, but there is no unifying formal explanation of their origins and role. In the present study, we used reinf...

Humans take the visuospatial perspective of robots and objects that imply social presence.

Acta psychologica Feb 18, 2025
Visual perspective-taking (VPT) plays a crucial role in social interactions. Although the mechanisms behind VPT have been thoroughly studied in human-human interactions, there are only a few studies examining whether humans can also adopt the visuosp...

Enhancing spatial perception and contextual understanding for 3D dense captioning.

Neural networks : the official journal of the International Neural Network Society Feb 10, 2025
3D dense captioning (3D-DC) transcends traditional 2D image captioning by requiring detailed spatial understanding and object localization, aiming to generate high-quality descriptions for objects within 3D environments. Current approaches struggle w...

Self-supervised learning of scale-invariant neural representations of space and time.

Journal of computational neuroscience Jan 22, 2025
Hippocampal representations of space and time seem to share a common coding scheme characterized by neurons with bell-shaped tuning curves called place and time cells. The properties of the tuning curves are consistent with Weber's law, such that, in...

Object and spatial discrimination makes weakly supervised local feature better.

Neural networks : the official journal of the International Neural Network Society Sep 12, 2024
Local feature extraction plays a crucial role in numerous critical visual tasks. However, there remains room for improvement in both descriptors and keypoints, particularly regarding the discriminative power of descriptors and the localization precis...

Mammalian-brain-inspired neuromorphic motion-cognition nerve achieves cross-modal perceptual enhancement.

Nature communications Mar 11, 2023
Perceptual enhancement of neural and behavioral response due to combinations of multisensory stimuli are found in many animal species across different sensory modalities. By mimicking the multisensory integration of ocular-vestibular cues for enhance...

An integrated deep learning-based model of spatial cells that combines self-motion with sensory information.

Hippocampus Aug 10, 2022
A special class of neurons in the hippocampal formation broadly known as the spatial cells, whose subcategories include place cells, grid cells, and head direction cells, are considered to be the building blocks of the brain's map of the spatial worl...

Recurrent amplification of grid-cell activity.

Hippocampus Oct 6, 2020
High-level cognitive abilities such as navigation and spatial memory are thought to rely on the activity of grid cells in the medial entorhinal cortex (MEC), which encode the animal's position in space with periodic triangular patterns. Yet the neura...

Decoding attention control and selection in visual spatial attention.

Human brain mapping Jun 16, 2020
Event-related potentials (ERPs) are used extensively to investigate the neural mechanisms of attention control and selection. The univariate ERP approach, however, has left important questions inadequately answered. We addressed two questions by appl...
