Molecular and functional PET-fMRI measures of placebo analgesia in episodic migraine: Preliminary findings
Clas Linnman,Clas Linnman,Ciprian Catana,Mike P. Petkov,Daniel B. Chonde,Lino Becerra,Jacob M. Hooker,David Borsook +7 more
TL;DR: Investigation of placebo analgesia in healthy subjects and in interictal migraine patients and matched healthy controls using 11C-diprenoprhine Positron Emission Tomography (PET) and simultaneous functional Magnetic Resonance Imaging (fMRI) found no evidence for an altered placebo response.

ADORA2A genotype modulates interoceptive and exteroceptive processing in a fronto-insular network
Maximilian J. Geiger,Katharina Domschke,György A. Homola,Stefan M. Schulz,Johannes Nowak,Atae Akhrif,Paul Pauli,Jürgen Deckert,Susanne Neufang +8 more
TL;DR: Fronto-insular connectivity in synopsis with ADORA2A genotypic information could serve as combined biomarkers for personalized treatment approaches in anxiety disorders targeting exteroceptive and interoceptive dysfunction.
Journal ArticleDOI
Decreased Functional Connectivity Between the Right Precuneus and Middle Frontal Gyrus Is Related to Attentional Decline Following Acute Sleep Deprivation.
TL;DR: In this paper, the authors used resting-state functional magnetic resonance imaging to study the relationship between the changes of the precuneus functional connectivity and alertness decline after total sleep deprivation.
Journal ArticleDOI
Potential Locations for Noninvasive Brain Stimulation in Treating Autism Spectrum Disorders-A Functional Connectivity Study.
TL;DR: This work conducted a meta-analysis on 170 functional magnetic resonance imaging studies to identify ASD-associated brain regions and identified potential NIBS targets for ASD, finding the medial prefrontal cortex, angular gyrus, and supplementary motor area/paracentral gyrus are potential locations for NIBS in ASD.

Neural representations of awe: Distinguishing common and distinct neural mechanisms.
Ryota Takano,Michio Nomura +1 more
TL;DR: It is found that both awe experiences deactivated the left middle temporal gyrus (MTG) in contrast to control conditions, which suggest that awe experiences generally involve the "schema liberation" process since the left MTG plays a critical role in matching existing schema to events.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

A default mode of brain function.
Marcus E. Raichle,Ann Mary MacLeod,Abraham Z. Snyder,William J. Powers,Debra A. Gusnard,Gordon L. Shulman +5 more
TL;DR: A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.

Complex brain networks: graph theoretical analysis of structural and functional systems
Edward T. Bullmore,Olaf Sporns +1 more
TL;DR: This article reviews studies investigating complex brain networks in diverse experimental modalities and provides an accessible introduction to the basic principles of graph theory and highlights the technical challenges and key questions to be addressed by future developments in this rapidly moving field.
Journal ArticleDOI
Functional connectivity in the motor cortex of resting human brain using echo-planar MRI.
TL;DR: It is concluded that correlation of low frequency fluctuations, which may arise from fluctuations in blood oxygenation or flow, is a manifestation of functional connectivity of the brain.

The Brain's Default Network Anatomy, Function, and Relevance to Disease
TL;DR: Past observations are synthesized to provide strong evidence that the default network is a specific, anatomically defined brain system preferentially active when individuals are not focused on the external environment, and for understanding mental disorders including autism, schizophrenia, and Alzheimer's disease.
