Associations between PACAP levels and psychophysiological indicators of fear and arousal in adults with posttraumatic stress symptoms

Journal of Mood and Anxiety Disorders
Posttraumatic stress disorder (PTSD) is associated with heightened fear responding and decreased fear regulation, as demonstrated with psychophysiological measures (e.g., autonomic function) and circulating biomarkers of stress, such as pituitary ...

Connecting the Dots: History Gathering in Anxiety Diagnosis

In this chapter, the case of Ms. A, a 33yearold married female, serves as a starting point to explore the complexities of diagnosing anxiety disorders. Ms. A presents with a yearlong struggle marked by excessive worry, fear, and physical symptoms such as

Schooling Trajectories and the Development of Brain Dynamics: A Comparative Study of Montessori and Traditional Education

Advanced Science, EarlyView.
We investigate whether Montessori and traditional schooling systems shape the developmental trajectory of large‐scale brain dynamics in different ways. We quantify the arrow of time (“non‐reversibility”) in neural activity during resting state and movie‐watching, revealing distinct maturational patterns.

Exploring individual differences in fear extinction in male and female mice: insights from HPA axis, microbiota, and transcriptomics

Translational Psychiatry
Exposure to traumatic life events may compromise physical and mental health of specific subjects. While some individuals extinguish fear appropriately, others exhibit an inefficient and persistent fear response, with remarkable differences between sexes.

Large‐Scale Quantitative Morphometry of Platelet α‐Granules via SIM Super‐Resolution Microscopy for Cancer Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Blood‐based liquid biopsies hold transformative potential for non‐invasive cancer management, but current approaches relying on rare circulating tumor components limit their broad clinical utility. Platelets, abundant in blood and mediating diverse cancer‐associated responses, represent a compelling yet largely unexplored alternative.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Health anxiety in obsessive compulsive disorder and obsessive compulsive symptoms in severe health anxiety : An investigation of symptom profiles

, 2017
Severe health anxiety (SHA) shares features with obsessive-compulsive disorder (OCD) and in recent years there has been a debate as to whether the two disorders may represent two facets of the same condition.

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

Advanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Palatable‐Food–Driven Top‐Down Circuit Inhibits PVNCRF Activity to Mitigate Stress Via Peri‐PVNCRFR1 Neurons

Advanced Science, EarlyView.
Palatable food alleviates stress and prevents anxiety. This study uncovers a dedicated neural pathway: dopamine release in the PFC activates D1R neurons, whose projections to the peri‐PVN engage a population of anxiolytic CRFR1 neurons. These neurons then inhibit stress‐induced hyperactivity of PVNCRF neurons, providing a circuit‐level explanation for ...

Effect of sleep quality on repetitive transcranial magnetic stimulation outcomes in depression

Frontiers in Psychiatry
IntroductionWhile repetitive transcranial magnetic stimulation (rTMS) is effective for 50-60% of those treatment-resistant depression, it is critical to identify predictors of response for optimal patient selection to improve therapy. Insomnia is a known
