MRI Epicenters Differentiate Spatiotemporal Patterns of Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A connectivity‐based MRI epicenter model identifies two Parkinson's disease subtypes: subtype 1 with infratentorial‐dominant epicenters, severe motor symptoms, and rapid progression; and subtype 2 with supratentorial‐dominant epicenters with mild progression.

Cingulate cortex function and multi-modal connectivity mapped using intracranial stimulation

open access: yesNeuroImage, 2020
The cingulate cortex is part of the limbic system. Its function and connectivity are organized in a rostro-caudal and ventral-dorsal manner which was addressed by various other studies using rather coarse cortical parcellations.

Neural signatures of cognitive flexibility and reward sensitivity following nicotinic receptor stimulation in dependent smokers : a randomized trial [PDF]

open access: yes, 2017
IMPORTANCE Withdrawal from nicotine is an important contributor to smoking relapse. Understanding how reward-based decision making is affected by abstinence and by pharmacotherapies such as nicotine replacement therapy and varenicline tartrate may aid ...

Unraveling Multimodal Brain Signatures: Deciphering Transdiagnostic Dimensions of Psychopathology in Adolescents

open access: yesAdvanced Intelligent Systems, EarlyView.
This study, utilizing two large‐cohort datasets, employs interpretable neural networks. It demonstrates that incorporating brain morphology and functional and structural networks enhances predictive accuracy for general psychopathology and its dimensions.

Blood α‐Synuclein Separates Parkinson's Disease from Dementia with Lewy Bodies

open access: yesAnnals of Neurology, EarlyView.
Objective Aggregation of misfolded α‐synuclein (aSyn) within the brain is the pathologic hallmark of Lewy body diseases (LBDs), including Parkinson's disease (PD), and dementia with Lewy bodies (DLB) disease. Although evidence exists for aSyn “strains,” conformations with distinct biological properties, biomarkers for PD versus DLB are lacking.

A neuroimaging study of pleasant and unpleasant olfactory perceptions of virgin olive oil [PDF]

open access: yes, 2016
Functional magnetic resonance imaging (fMRI) has been used to collect information from neurons that receive direct input from olfactory bulbs when subjects smell virgin olive oil. The pleasant aroma of three extra virgin olive oils (var.

The Relationship between Rest Tremor and Underlying Lewy Pathology in Essential Tremor: A Clinical‐Pathological Study of 201 Cases

open access: yesAnnals of Neurology, EarlyView.
Objectives Prospective studies demonstrated that essential tremor is a risk factor for Parkinson's disease. Identifying clinical markers for conversion from essential tremor to essential tremor‐Parkinson's disease would be of considerable value. Rest tremor can be present in advanced essential tremor and may be a harbinger of conversion. We examined (1)

Interactions between visceral afferent signaling and stimulus processing [PDF]

open access: yes, 2015
Visceral afferent signals to the brain influence thoughts, feelings and behaviour. Here we highlight the findings of a set of empirical investigations in humans concerning body-mind interaction that focus on how feedback from states of autonomic arousal ...
