Two-Dimensional Population Receptive Field Mapping of Human Primary Somatosensory Cortex (2023)
Journal Article

Functional magnetic resonance imaging can provide detailed maps of how sensory space is mapped in the human brain. Here, we use a novel 16 stimulator setup (a 4 × 4 grid) to measure two-dimensional sensory maps of between and within-digit (D2–D4) spa...

fRAT: an interactive, Python-based tool forregion-of-interest summaries of functional imaging data (2023)
Journal Article

Functional magnetic resonance imaging (fMRI) is widely used to address basic cognitive as well as clinical neuroscience questions. The specific choice of imaging sequence and parameters used for image acquisition can have a marked effect on the acqui...

fMRI evidence that hyper-caricatured faces activate object-selective cortex (2023)
Journal Article

Many brain imaging studies have looked at the cortical responses to object categories and faces. A popular way to manipulate face stimuli is by using a “face space,” a high dimensional representation of individual face images, with the average face l...

The effects of simulated hemianopia on eye movements during text reading (2022)
Journal Article

Vision loss is a common, devastating complication of cerebral strokes. In some cases the complete contra-lesional visual field is affected, leading to problems with routine tasks and, notably, the ability to read. Although visual information crucial...

Fast Event-Related Mapping of Population Fingertip Tuning Properties in Human Sensorimotor Cortex at 7T (2022)
Journal Article

fMRI studies that investigate somatotopic tactile representations in the human cortex typically use either block or phase-encoded stimulation designs. Event-related (ER) designs allow for more flexible and unpredictable stimulation sequences than the...

Linking Multi-Modal MRI to Clinical Measures of Visual Field Loss After Stroke (2022)
Journal Article

Loss of vision across large parts of the visual field is a common and devastating complication of cerebral strokes. In the clinic, this loss is quantified by measuring the sensitivity threshold across the field of vision using static perimetry. These...

A probabilistic atlas of finger dominance in the primary somatosensory cortex (2020)
Journal Article

With the advent of ultra-high field (7T), high spatial resolution functional MRI (fMRI) has allowed the differentiation of the cortical representations of each of the digits at an individual-subject level in human primary somatosensory cortex (S1). H... Read More about A probabilistic atlas of finger dominance in the primary somatosensory cortex.

Somatotopy in the human somatosensory system (2018)
Journal Article

Previous functional magnetic resonance imaging (fMRI) studies have demonstrated digit somatotopy in primary somatosensory cortex (SI), and even shown that at high spatial resolution it is possible to resolve within-digit somatotopy. However, fMRI stu... Read More about Somatotopy in the human somatosensory system.

Exploring structure and function of sensory cortex with 7 T MRI (2017)
Journal Article

In this paper, we present an overview of 7 Tesla magnetic resonance imaging (MRI) studies of the detailed function and anatomy of sensory areas of the human brain. We discuss the motivation for the studies, with particular emphasis on increasing the... Read More about Exploring structure and function of sensory cortex with 7 T MRI.

Do perceptual biases emerge early or late in visual processing? Decision-biases in motion perception (2016)
Journal Article

Visual perception is strongly influenced by contextual information. A good example is reference repulsion, where subjective reports about the direction of motion of a stimulus are significantly biased by the presence of an explicit reference. These p...

7 Tesla fMRI reveals systematic functional organization for binocular disparity in dorsal visual cortex (2015)
Journal Article

© 2015 the authors. The binocular disparity between the views of the world registered by the left and right eyes provides a powerful signal about the depth structure of the environment. Despite increasing knowledge of the cortical areas that process... Read More about 7 Tesla fMRI reveals systematic functional organization for binocular disparity in dorsal visual cortex.

The influence of spatial pattern on visual short-term memory for contrast (2014)
Journal Article

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not dec... Read More about The influence of spatial pattern on visual short-term memory for contrast.

Event-related fMRI at 7T reveals overlapping cortical representations for adjacent fingertips in S1 of individual subjects (2013)
Journal Article

Recent fMRI studies of the human primary somatosensory cortex have been able to differentiate the cortical representations of different fingertips at a single-subject level. These studies did not, however, investigate the expected overlap in cortical...

Decoding working memory of stimulus contrast in early visual cortex (2013)
Journal Article

Most studies of the early stages of visual analysis (V1-V3) have focused on the properties of neurons that support processing of elemental features of a visual stimulus or scene, such as local contrast, orientation, or direction of motion. Recent evi... Read More about Decoding working memory of stimulus contrast in early visual cortex.

Regional structural differences across functionally parcellated Brodmann areas of human primary somatosensory cortex (2013)
Journal Article

Ultra-high-field (UHF) MRI is ideally suited for structural and functional imaging of the brain. High-resolution structural MRI can be used to map the anatomical boundaries between functional domains of the brain by identifying changes related to the...
