The paper uses ultrafast fMRI and a Layer-based Connective Field model to distinguish feedforward and feedback signaling in cortical circuits, revealing distinct layer-specific connectivity patterns.

This study maps brain-wide visual receptive fields and spatial frequency tuning in adult rats after visual experience, showing topographic remapping and functional sharpening.

This study investigates neuroplasticity in adult glaucomatous visual cortex using fMRI and finds reduced fMRI signal amplitude and local pRF shifts in early visual areas.

This study investigates functional connectivity changes in primary open-angle glaucoma using resting-state fMRI and finds local network alterations linked to visual field deficits.

The paper introduces SANDI, a diffusion MRI method for characterizing cellular and neurite densities in mouse brains, showing strong correlation with the Allen brain atlas.

This study evaluates fMRI-based techniques for visual field reconstruction, finding they can detect large VF defects and provide reliable VF information comparable to standard automated perimetry.

The paper shows that foveal pRF properties in healthy controls change when peripheral visual field stimulation is restricted, suggesting caution in interpreting similar changes in patients with visual field defects.

This paper introduces micro-probing (MP), a method to map neuronal subpopulation receptive fields in humans using fMRI without prior assumptions, revealing subpopulations in both healthy and diseased states.

The paper investigates how the human visual cortex reconfigures neural populations in response to an artificial scotoma, finding shifts in receptive fields and connectivity guided by extrastriate signals.
