The paper measures cortical magnification in human visual cortex and finds it correlates with visual field task performance and heritability in twins.

The paper uses population receptive field modeling to show a functional hierarchy in human primary somatosensory cortex, with increasing pRF sizes from BA3 to BA2.

The paper evaluates the shape of population receptive fields in early visual cortex, finding that aspect ratios are less than 2, contradicting previous claims of highly elliptical shapes.

This study systematically examines contrast sensitivity asymmetries across visual field meridians under varying stimulus parameters and finds consistent patterns despite parameter changes.

The paper introduces a framework for validating neuroimaging software using ground-truth testing, applied to population receptive field analysis in fMRI data.

The paper presents a computational model of temporal dynamics in visual cortex that explains diverse temporal phenomena across multiple measurement types and cortical areas.

The paper develops a model to predict gamma oscillation responses to arbitrary images and validates it on human ECoG data, finding that gamma responses are stimulus-specific and may indicate gain control rather than information transfer.

The paper develops a computational observer model to investigate how early visual system properties like optics and cone density contribute to polar angle-dependent visual performance differences, finding they cannot fully explain the observed asymmetries.

This paper introduces a Bayesian method for retinotopic mapping that improves accuracy by combining fMRI data with a learned atlas, enabling automated analysis and quantification of map differences.

The paper estimates visual onset latencies in human posterior parietal cortex using ECoG recordings and finds early responses in the posterior intra-parietal sulcus comparable to peristriate visual areas.

The paper describes a large-scale retinotopy dataset from the HCP and presents population receptive field analysis results from both individual subjects and group averages.

This paper develops a denoising method for MEG to quantify broadband spectral responses in human visual cortex, showing they correlate with spike rates and can be reliably measured non-invasively.

This paper investigates temporal processing in the human visual cortex using fMRI, finding sub-additive summation and adaptation, and proposes a model that parallels spatial compressive summation.

The paper models neuronal population responses and their transformations into BOLD and ECoG signals, finding that BOLD and ECoG provide complementary information with distinct relationships to neuronal synchrony.

The paper maps and characterizes visual field map clusters in human frontoparietal cortex using a novel task and nonlinear population receptive field modeling, revealing topographic organization similar to visual cortex.
