The medial subdivision of the inferior pulvinar (PIm) has been implicated in motion processing, visuomotor integration, and residual visual function, yet a comprehensive account of its cortical inputs remains unresolved. Previous studies often relied on indirect cortical injections or tracer deposits spanning multiple…

To better understand the cortical connections and organization of visual areas in galagos, we examined the interconnections among cortical visual fields and their relationships with posterior parietal cortex (PPC) and temporal regions associated with dorsal and ventral streams of visual processing. In five galagos, two…

Cortical visual prostheses aim to restore sight by stimulating the visual cortex, yet current approaches remain limited. Implants targeting V1 typically evoke isolated phosphenes that do not support coherent object recognition. We asked whether mid-level visual features, specifically curve segments associated with area…

Progress in vision research has been slower downstream than upstream of primary visual cortex (V1). Traditional frameworks have largely overlooked a central constraint: only a tiny fraction of retinal input is recognized. Thus, to a first approximation, vision is better formulated as looking and seeing through a…

Primary visual cortex (V1) is a critical substrate for mammalian vision. Traditionally, visual inputs are thought to be the main drivers of V1 activity, with internal signals playing a modulatory role. Here we show that this relationship is inverted for a large fraction of V1 neurons. In rats completing a navigation…

Influential models of primate visual cortex describe two functionally distinct pathways: a ventral pathway for object recognition and the dorsal pathway for spatial and action processing. However, recent human and non-human primate research suggests the existence of a third visual pathway projecting from early visual…

If you peel off the gray matter of the cerebral cortex, like the rind from an orange, you will recover a sheet of tissue. This sheet contains the neuron cell bodies responsible for sensory perception, long-term memory, problem solving, and decision-making. Understanding how it works is daunting because science…

Neurons in cortical areas often integrate signals from different origins. In the primary visual cortex (V1), neural responses are modulated by non-visual context such as the animal's position. However, the spatial profile of these position signals across the environment remains unknown. Here, we propose a new framework…

One major distinction between artificial neural networks and biological brains is the prevalence of extensive, long-range feedback connections in biological systems. Here we investigate unique contributions of these hierarchical feedback signals beyond feedforward processing and local recurrence by exploring their…

A fine-grained account of functional selectivity in the cortex is essential for understanding how visual information is processed and represented in the brain. Classical studies using designed experiments have identified multiple category-selective regions; however, these approaches rely on preconceived hypotheses…

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…

A central goal in understanding human vision is to uncover the visual features that drive neuronal activity. A growing body of work has used artificial neural networks as encoding models to predict cortical responses to natural images, revealing the visual content that activates category-selective regions. However…

Visual recognition is a fundamental human brain function, supported by a network of regions in the ventral occipito-temporal cortex (VOTC). This network is thought to be organized hierarchically, with definite processing stages increasing in invariance and time-course from posterior to anterior cortical regions. Here…

For decades, visual perception was treated as a linear, feature-extracting mechanism driven almost exclusively by bottom-up sensory inputs. Emerging insights from affective neuroscience and cognitive psychology have systematically dismantled this view, revealing that vision operates within a continuous, bidirectional…

Mammals rely on their senses to establish their position in space. Neural activity in the hippocampus maps position, yet how sensory signals reach the hippocampus remains poorly understood. Here we uncover the visual pathways informing spatial maps in the mouse hippocampus. Hippocampal activity in mice traversing a…

The role of the cerebellum has long been thought to be limited to sensorimotor processes. Recently, its involvement in a broader set of cognitive and associative tasks has challenged this view. Recent studies have expanded the cerebellum's functional repertoire into the visual domain, by identifying three…

Eidetic imagery is experienced as “seen” in external space, unlike typical visual mental imagery, which occurs in the mind’s eye. To investigate whether eidetic imagery and perception share common neural substrates, we measured brain activity in eidetikers and typical imagers using fMRI while they performed perception…

This paper formally defines an operational isomorphism between spectral damping in molecular vibronic systems and neuromodulatory control in biological sensory systems. Without asserting causal continuity or physical identity across scales, we show that both domains instantiate the same class of output-selective…

The extrastriate body area is a functional region of the human brain located in the lateral occipitotemporal cortex and was originally identified by its greater activation in response to images of human bodies compared with several other object categories. In subsequent research, the extrastriate body area was…
