Serial correlations in single-subject fMRI with sub-second TR

S Bollmann, AM Puckett, R Cunnington, M Barth - NeuroImage, 2018 - Elsevier
When performing statistical analysis of single-subject fMRI data, serial correlations need to
be taken into account to allow for valid inference. Otherwise, the variability in the parameter …

Measuring the effects of attention to individual fingertips in somatosensory cortex using ultra-high field (7T) fMRI

AM Puckett, S Bollmann, M Barth, R Cunnington - Neuroimage, 2017 - Elsevier
Attention to sensory information has been shown to modulate the neuronal processing of
that information. For example, visuospatial attention acts by modulating responses at …

[HTML][HTML] Bayesian population receptive field modeling in human somatosensory cortex

AM Puckett, S Bollmann, K Junday, M Barth… - Neuroimage, 2020 - Elsevier
Somatosensation is fundamental to our ability to sense our body and interact with the world.
Our body is continuously sampling the environment using a variety of receptors tuned to …

Using multi-echo simultaneous multi-slice (SMS) EPI to improve functional MRI of the subcortical nuclei of the basal ganglia at ultra-high field (7T)

AM Puckett, S Bollmann, BA Poser, J Palmer, M Barth… - NeuroImage, 2018 - Elsevier
The nuclei of the basal ganglia pose a special problem for functional MRI, especially at ultra-high
field, because T2* variations between different regions result in suboptimal BOLD …

The attentional field revealed by single-voxel modeling of fMRI time courses

AM Puckett, EA DeYoe - Journal of Neuroscience, 2015 - Soc Neuroscience
The spatial topography of visual attention is a distinguishing and critical feature of many
theoretical models of visuospatial attention. Previous fMRI-based measurements of the …

[HTML][HTML] Manipulating the structure of natural scenes using wavelets to study the functional architecture of perceptual hierarchies in the brain

AM Puckett, MM Schira, ZJ Isherwood, JD Victor… - NeuroImage, 2020 - Elsevier
Functional neuroimaging experiments that employ naturalistic stimuli (natural scenes, films,
spoken narratives) provide insights into cognitive function “in the wild”. Natural stimuli …

An investigation of positive and inverted hemodynamic response functions across multiple visual areas

AM Puckett, JR Mathis, EA DeYoe - Human brain mapping, 2014 - Wiley Online Library
Recent studies have demonstrated significant regional variability in the hemodynamic
response function (HRF), highlighting the difficulty of correctly interpreting functional MRI (fMRI) …

[HTML][HTML] Predicting the retinotopic organization of human visual cortex from anatomy using geometric deep learning

FL Ribeiro, S Bollmann, AM Puckett - NeuroImage, 2021 - Elsevier
Whether it be in a single neuron or a more complex biological system like the human brain,
form and function are often directly related. The functional organization of human visual …

Highly accurate retinotopic maps of the physiological blind spot in human visual cortex

PWB Urale, AM Puckett, A York, D Arnold… - 2022 - Wiley Online Library
The physiological blind spot is a naturally occurring scotoma corresponding with the optic disc
in the retina of each eye. Even during monocular viewing, observers are usually oblivious …
