Neurovascular multiparametric MRI defines epileptogenic and seizure propagation regions in experimental mesiotemporal lobe epilepsy.
Epilepsia
Apr 5, 2021
OBJECTIVE: Improving the identification of the epileptogenic zone and associated seizure-spreading regions represents a significant challenge. Innovative brain-imaging modalities tracking neurovascular dynamics during seizures may provide new disease...
Neurophysiological brain mapping of human sleep-wake states.
Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology
Apr 1, 2021
OBJECTIVE: We recently proposed a spectrum-based model of the awake intracranial electroencephalogram (iEEG) (Kalamangalam et al., 2020), based on a publicly-available normative database (Frauscher et al., 2018). The latter has been expanded to inclu...
Brain tissues have single-voxel signatures in multi-spectral MRI.
NeuroImage
Mar 20, 2021
Since the seminal works by Brodmann and contemporaries, it is well-known that different brain regions exhibit unique cytoarchitectonic and myeloarchitectonic features. Transferring the approach of classifying brain tissues - and other tissues - based...
Decoding with confidence: Statistical control on decoder maps.
NeuroImage
Mar 12, 2021
In brain imaging, decoding is widely used to infer relationships between brain and cognition, or to craft brain-imaging biomarkers of pathologies. Yet, standard decoding procedures do not come with statistical guarantees, and thus do not give confide...
Automatic attenuation map estimation from SPECT data only for brain perfusion scans using convolutional neural networks.
Physics in medicine and biology
Mar 4, 2021
In clinical brain SPECT, correction for photon attenuation in the patient is essential to obtain images which provide quantitative information on the regional activity concentration per unit volume (kBq.[Formula: see text]). This correction generally...
Human cortical encoding of pitch in tonal and non-tonal languages.
Nature communications
Feb 19, 2021
Languages can use a common repertoire of vocal sounds to signify distinct meanings. In tonal languages, such as Mandarin Chinese, pitch contours of syllables distinguish one word from another, whereas in non-tonal languages, such as English, pitch is...
Within-category representational stability through the lens of manipulable objects.
Cortex; a journal devoted to the study of the nervous system and behavior
Feb 5, 2021
Our ability to recognize an object amongst many exemplars is one of our most important features, and one that putatively distinguishes humans from non-human animals and potentially from (current) computational and artificial intelligence models. We c...
Functional parcellation of mouse visual cortex using statistical techniques reveals response-dependent clustering of cortical processing areas.
PLoS computational biology
Feb 4, 2021
The visual cortex of the mouse brain can be divided into ten or more areas that each contain complete or partial retinotopic maps of the contralateral visual field. It is generally assumed that these areas represent discrete processing regions. In co...
Deep Representation-Based Domain Adaptation for Nonstationary EEG Classification.
IEEE transactions on neural networks and learning systems
Feb 4, 2021
In the context of motor imagery, electroencephalography (EEG) data vary from subject to subject such that the performance of a classifier trained on data of multiple subjects from a specific domain typically degrades when applied to a different subje...
Identify abnormal functional connectivity of resting state networks in Autism spectrum disorder and apply to machine learning-based classification.
Brain research
Jan 29, 2021
Autism spectrum disorder (ASD) patients are often reported altered patterns of functional connectivity (FC) on resting-state functional magnetic resonance imaging (rsfMRI) scans. However, the results in similar brain regions were inconsistent. In thi...
