Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Neuronal basis of high frequency fMRI fluctuation: direct evidence from simultaneous recording

Frontiers in Human Neuroscience
Resting-state functional magnetic resonance imaging (RS-fMRI) has been extensively utilized for noninvasive investigation of human brain activity. While studies employing simultaneous recordings of fMRI and electrophysiology have established a connection

Brain-wide Mapping of Endogenous Serotonergic Transmission via Chemogenetic fMRI

Cell Reports, 2017
Summary: Serotonin-producing neurons profusely innervate brain regions via long-range projections. However, it remains unclear whether and how endogenous serotonergic transmission specifically influences regional or global functional activity.

Show Me the Brain!!: A modern approach to neuroanatomy education

Anatomical Sciences Education, EarlyView.
Abstract Show Me the Brain!! (SMtB) is a digital system for interactive graphics that is designed to support instruction in neuroanatomy and neuroscience. It will soon be made open‐source and freely available. SMtB bridges medical and traditional neuroanatomy instruction with the computational systems and representational conventions common in ...

Relation between functional magnetic resonance imaging (fMRI) and single neuron, local field potential (LFP) and electrocorticography (ECoG) activity in human cortex

Frontiers in Human Neuroscience, 2013
The relation between changes in the blood oxygen dependent metabolic changes imaged by functional magnetic resonance imaging (fMRI) and neural events directly recorded from human cortex from single neurons, local field potentials (LFPs) and ...

Methodological problems in fMRI studies on acupuncture: a critical review with special emphasis on visual and auditory cortex activations

, 2011
Functional magnetic resonance imaging (fMRI) has been used for more than a decade to investigate possible supraspinal mechanisms of acupuncture stimulation. More than 60 studies and several review articles have been published on the topic.

Atypical Predictive Processing Is Associated With Sensory Over‐Responsivity in Autism

Autism Research, EarlyView.
ABSTRACT Autism is characterized by sensory processing atypicalities including sensory over‐responsivity (SOR), a heightened negative response to sensory stimuli. Although the neural mechanisms underlying SOR are not fully understood, SOR has been associated with sensory‐limbic hyper‐reactivity during sensory stimulation.

Informational and Normative Influence on Conformity in Autism

Autism Research, EarlyView.
ABSTRACT This preregistered study examined whether adults with autism spectrum disorder (ASD) show reduced social conformity and whether any such reduction depends on the type of social influence. Social conformity—the tendency to adjust one's judgments to align with those of others—is typically driven by normative (acceptance‐seeking) and ...
