Psilocybin alters visual contextual computations [PDF]

Nature Communications
Psilocybin alters perception and brain dynamics. Here, we investigate the effects of psilocybin using psychophysics, ultra-high field functional MRI, and computational modeling.

Individualized cognitive neuroscience needs 7T: Comparing numerosity maps at 3T and 7T MRI

NeuroImage, 2021
The field of cognitive neuroscience is weighing evidence about whether to move from the current standard field strength of 3 Tesla (3T) to ultra-high field (UHF) of 7T and above.

Topographic numerosity maps cover subitizing and estimation ranges

Nature Communications, 2021
Here, the authors show that the brain represents small and large numerosity ranges in a continuous topographic map, in line with the idea that differences in map properties underlie differences in perception.

Topographic maps representing haptic numerosity reveals distinct sensory representations in supramodal networks

Nature Communications, 2021
Topographically organized tuned responses to haptic numerosity were found in the human brain. The responses to visual or haptic numerosity shared a similar large-scale cortical network, yet the maps of the two modalities only partially overlapped ...

Can 7T MPRAGE match MP2RAGE for gray-white matter contrast?

NeuroImage, 2021
Ultra-High Field (UHF) MRI provides a significant increase in Signal-to-Noise Ratio (SNR) and gains in contrast weighting in several functional and structural acquisitions. Unfortunately, an increase in field strength also induces non-uniformities in the

Comparing hand movement rate dependence of cerebral blood volume and BOLD responses at 7T

NeuroImage, 2021
Functional magnetic resonance imaging (fMRI) based on the Blood Oxygenation Level Dependent (BOLD) contrast takes advantage of the coupling between neuronal activity and the hemodynamics to allow a non-invasive localisation of the neuronal activity.

Comparing BOLD and VASO-CBV population receptive field estimates in human visual cortex

NeuroImage, 2022
Vascular Space Occupancy (VASO) is an alternative fMRI approach based on changes in Cerebral Blood Volume (CBV). VASO-CBV fMRI can provide higher spatial specificity than the blood oxygenation level-dependent (BOLD) method because the CBV response is ...

Advances in resting state fMRI acquisitions for functional connectomics

NeuroImage, 2021
Resting state functional magnetic resonance imaging (rs-fMRI) is based on spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal, which occur simultaneously in different brain regions, without the subject performing an explicit task ...

Reliable, versatile and remotely controlled instrumentation of an hectometric loop antenna using appropriate technologies

HardwareX, 2023
The instrumentation of a giant loop antenna dedicated to environmental measurement, on a unique scientific site and intended to be open to the scientific community is presented. An open-source, low-cost electronic system has been designed, developed, and
