DOI: 10.1016/j.neuroimage.2020.116853
Abstract: An essential task of neuroscience is to elucidate the relationship between brain activity, brain structure, and human behavior. This study aims to understand this 3-way relationship by studying the population covariance of resting-state functional connectivity,… read more here.

DOI: 10.1016/j.neuron.2017.11.004
Abstract: Visual cortical areas are interconnected via layer-specific feedforward and feedback projections. Such intricate connections are thought to be essential for parsing complex visual images, but the synergy among different layers in different cortical areas remains… read more here.

DOI: 10.1038/s41598-020-62165-x
Abstract: A fundamental assumption of nearly all functional magnetic resonance imaging (fMRI) analyses is that the relationship between local neuronal activity and the blood oxygenation level dependent (BOLD) signal can be described as following linear systems… read more here.

DOI: 10.3389/fnins.2023.1138602
Abstract: Local field potentials (LFPs) can evaluate neural population activity in the cortex and their interaction with other cortical areas. Analyzing current source density (CSD) rather than LFPs is very significant due to the reduction of… read more here.

DOI: 10.7554/elife.46856
Abstract: In our environment, our senses are bombarded with a myriad of signals, only a subset of which is relevant for our goals. Using sub-millimeter-resolution fMRI at 7T, we resolved BOLD-response and activation patterns across cortical… read more here.
