Whole‐Brain Diffusion MRI at 7T With Universal Multiband GRAPE pTx Pulses

Magnetic Resonance in Medicine, EarlyView.
Purpose To improve signal strength and homogeneity of whole‐brain diffusion‐weighted imaging (DWI) at 7T. Methods Universal multiband excitation and refocusing pulses were optimized with the gradient ascent pulse engineering (GRAPE) algorithm across a database of B1+$$ {B}_1^{+} $$ and B0$$ {B}_0 $$ maps obtained from 20 subjects.

Association of Nasal Anatomy, Airflow, and Surgery With Olfactory Outcomes: A State‐of‐the‐Art Review

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Olfactory function is influenced by nasal airflow dynamics and anatomical variations within the nasal cavity. This narrative review evaluates how nasal anatomy and airflow relate to olfactory outcomes, with a particular focus on olfactory changes following functional nasal surgery. Data Sources PubMed.

The Role of Repetitive Transcranial Magnetic Stimulation in Modulating Autonomic Dysfunction in Irritable Bowel Syndrome rTMS for IBS Autonomic Dysfunction

Sensory Neuroscience, EarlyView.
Irritable bowel syndrome (IBS) is associated with dysregulation of the autonomic nervous system and altered brain–gut communication. rTMS may alleviate IBS symptoms by modulating central autonomic and pain‐processing networks, potentially restoring sympathovagal balance and reducing visceral hypersensitivity.

Brain reward function in young people with cannabis use disorder: A functional magnetic resonance imaging study

Addiction, EarlyView.
Abstract Background and Aims Cannabis use disorder (CUD) affects ~50 million people globally. Neuroscientific theories suggest that a blunted neural response to non‐drug rewards is a hallmark of substance use disorders; however, this remains untested in CUD. The current study tested whether brain reward system responses to the anticipation and feedback

Opioid withdrawal syndrome‐associated cognitive impairment: A narrative review

The American Journal on Addictions, EarlyView.
Abstract Background and Objectives Opioid withdrawal syndrome (OWS) comprises a transient constellation of subjective symptoms and objective signs expressed by brain and other organs. Although cognitive impairment is well documented in opioid use and addiction, little is known about cognitive impairment that may specifically accompany OWS.

Effects of Noninvasive Cervical Vagal Nerve Stimulation on Cognitive Performance But Not Brain Activation in Healthy Adults

Neuromodulation: Technology at the Neural Interface, EarlyView., 2020
Abstract Objectives While preliminary evidence suggests that noninvasive vagal nerve stimulation (nVNS) may enhance cognition, to our knowledge, no study has directly assessed the effects of nVNS on brain function and cognitive performance in healthy individuals.

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and
