Callosal connections of primary visual cortex predict the spatial spreading of binocular rivalry across the visual hemifields

Frontiers in Human Neuroscience, 2011
In binocular rivalry, presentation of different images to the separate eyes leads to conscious perception alternating between the two possible interpretations every few seconds. During perceptual transitions, a stimulus emerging into dominance can spread

Deep neural networks on graph signals for brain imaging analysis

, 2017
Brain imaging data such as EEG or MEG are high-dimensional spatiotemporal data often degraded by complex, non-Gaussian noise. For reliable analysis of brain imaging data, it is important to extract discriminative, low-dimensional intrinsic representation

Iodine-123 labeled reboxetine analogues for imaging of noradrenaline transporter in brain using single photon emission computed tomography [PDF]

, 2012
Preliminary investigation of the radioiodinated (S,S)-reboxetine analogue, 123I-INER, in baboons showed this tracer to have promise for imaging the noradrenaline transporter (NAT) using single photon emission computed tomography (SPECT).

Impaired insight in schizophrenia is associated with higher frontoparietal cerebral blood flow: an arterial spin labeling study

Schizophrenia
Impaired insight into illness occurs in up to 98% of patients with schizophrenia, depending on the stage of illness, and leads to negative clinical outcomes.

Contrasting brain patterns of writing-related DTI parameters, fMRI connectivity, and DTI–fMRI connectivity correlations in children with and without dysgraphia or dyslexia

NeuroImage: Clinical, 2015
Based on comprehensive testing and educational history, children in grades 4–9 (on average 12 years) were diagnosed with dysgraphia (persisting handwriting impairment) or dyslexia (persisting word spelling/reading impairment) or as typical writers and ...

Neuroethical issues in adopting brain imaging for personalized chronic pain management: Attitudes of people with lived experience of chronic pain

Canadian Journal of Pain
Background Pain is an individual and subjective experience that places a burden on individuals to convince others they have pain. Brain imaging technologies can potentially inform pain management but raise neuroethical questions.Aims We examined the ...

Microtesla MRI of the human brain combined with MEG

, 2008
One of the challenges in functional brain imaging is integration of complementary imaging modalities, such as magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI).

Imaging brain development: The adolescent brain

NeuroImage, 2012
The past 15 years have seen a rapid expansion in the number of studies using neuroimaging techniques to investigate maturational changes in the human brain. In this paper, I review MRI studies on structural changes in the developing brain, and fMRI studies on functional changes in the social brain during adolescence.

MRI signatures of cortical microstructure in human development align with oligodendrocyte cell-type expression

Nature Communications
Neuroanatomical changes to the cortex during adolescence have been well documented using MRI, revealing ongoing cortical thinning and volume loss. Recent advances in MRI hardware and biophysical models of tissue informed by diffusion MRI data hold ...

An anatomical and functional topography of human auditory cortical areas

Frontiers in Neuroscience, 2014
While advances in magnetic resonance imaging (MRI) throughout the last decades have enabled the detailed anatomical and functional inspection of the human brain non-invasively, to date there is no consensus regarding the precise subdivision and ...
