In the functional neuroimaging of the human brain, the main effort so far has been put forward to cerebral localization of each function or functional specialization. Two examples based on the study by the author's group are presented: one on the cortical mechanism of pain perception in humans...
The human brain consists of multiple interconnected large scale networks. Recent advances in structural and functional neuroimaging techniques have introduced new concepts and approaches to noninvasively assess brain networks, which has attracted enormous research interest. To examine human brain function, tr...
Clusters in which the strength of functional connectivity with the PCC (seed) were significantly correlated with proactive aggression (Panel A). Colour bars represent t-values. Scatter plots (panels B–E) indicate a significant association between proactive aggression and functional connectivity strength ...
Functional connections form the building blocks of a functional network, and can be studied with neurophysiological techniques (for example, electroencephalography, EEG) and by neuroimaging (for example, functional MRI, fMRI). Compared to fMRI, EEG has poor spatial resolution and is subject to ...
Neural modeling and functional neuroimaging Two research areas that so far have had little interaction with one another are functional neuroimaging and computational neuroscience. The application of ... B Horwitz,O Sporns - 《Human Brain Mapping》 被引量: 163发表: 1993年 加载更多研究...
Brain areas refer to specific regions within the brain that can be defined by their unique pattern of input and output connections with the rest of the brain. These connections play a crucial role in determining the function of these areas. The advent of neuroimaging of connectivity has allowed...
The brain is an assembly of neuronal populations interconnected by structural pathways. Brain activity is expressed on and constrained by this substrate. Therefore, statistical dependencies between functional signals in directly connected areas can be ex
This paper attempt to describe differentneuroscientific methods in the field of cognitive neuroscience used to explore the cortical areas involved in face perception. The different brain mapping techniques and functionalneuroimaging methods discussed will mainly be lesion studies and single-cell recordings,...
No formal sample size calculation was performed because mastocytosis is a rare condition and no preliminary data have allowed defining the size or even the type of neuroimaging results. Consecutive patients were recruited during 18 months at Necker Children's Hospital (Paris, France). Inclusion ...
have independently found that the strength of structure-function coupling systematically varies across the brain. Structure and function are tightly coupled in primary sensorimotor areas but diverge in polysensory association areas, gradually decoupling along a macroscale functional gradient from unimodal to ...
