The processing of temporal concepts is known to be intertwined with spatial cognition. For instance, reaction times (RTs) are shorter when participants classify past- and future-related words with left- and right-lateral responses, respectively, in line with the so-called mental time line hypothesis. While some…

Cell-cell communication (CCC) is essential for maintaining tissue organization and driving biological progression, yet its inference from transcriptomic data has long been limited by the absence of spatial context. Advances in spatial transcriptomics (ST) now enable mechanistically grounded analyses of CCC by…

Bilaterian animals must integrate sensory input from both sides of their bodies to make coherent perceptual decisions. In Drosophila larvae, olfactory receptor neurons target the ipsilateral brain hemisphere. Using calcium imaging, unilateral sensory perturbations, connectome analysis, and optogenetics, we identified…

The primary goal of a brain-computer interface (BCI) is to enable interactions with the environment by generating control signals directly from brain activity, independent of physical movement including gaze shifts. Attentional selection of peripheral objects has been used to control a BCI but requires sufficient…

Animals need to infer properties of the environment that are only ambiguously encoded by neurons in the sensory periphery. In vision, local edge motion seen through small receptive fields does not uniquely specify the direction of global or object motion. Can these ambiguous local motion signals drive behavior…

Parallel visual streams segregate information into pathways specialized for distinct computations, but how this segregation is achieved by anatomical segregation of primary visual cortex output remains unclear. This problem is complicated because individual neurons frequently send broadcasting projections to multiple…

How transient neural representations become integrated and stable enough to function as internal neural models remains incompletely understood. Grounded in efficient coding, Bayesian and predictive frameworks, recurrent and attractor dynamics, neural state-space models, and systems neuroscience, the Principle of…

Memory consolidation during sleep depends on the precisely timed coordination of hippocampal reactivation with cortical slow oscillations and spindles. In humans this coupling has been characterised correlationally, while causal investigations have required intracranial stimulation in restricted patient cohorts or used…

Working memory representations of multiple items are maintained within quasi-orthogonal neural subspaces, a mechanism thought to reduce interference between memory contents. Previous studies in both non-human and human primates have demonstrated the existence of such subspaces, but it remains unclear how cognitive…

Neuronal magnetic signal recording intrinsically provides vector information and tissue transparency, offering a potential route to overcome the spatial resolution limitations of conventional electrophysiological recordings. However, in situ detection of neuronal magnetic signals at the cellular level remains highly…
