From helplessness to controllability: toward a neuroscience of resilience

Frontiers in Psychiatry, 2023
“Learned helplessness” refers to debilitating outcomes, such as passivity and increased fear, that follow an uncontrollable adverse event, but do not when that event is controllable. The original explanation argued that when events are uncontrollable the

Deep Learning for AD Risk Screening and Progression Prediction

Advanced Science, EarlyView.
A pretrained MRI‐based deep learning model generalizes from Western cohorts to an independent Chinese cohort, detects Alzheimer's disease with high sensitivity, and identifies elevated AD risk years before diagnosis. Its risk scores align with cognition and plasma biomarkers, and individualized brain risk maps uncover clinically distinct subtypes ...

Pressor and sympathetic responses to dorsal raphe nucleus infusions of TRH in rats

, 1990
Pressor, tachycardic, and sympathoexcitatory responses to intracerebroventricularly (icv) infused thyrotropin-releasing hormone (TRH) were recorded in urethan-anesthetized rats to identify where centrally administered TRH acts in the brain.

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Dorsal Nucleus Raphé

, 2008
This report contains a gene expression summary of the dorsal nucleus raphé (DR), derived from the Allen Brain Atlas (ABA) in-situ hybridization (ISH) mouse data set. The structure’s location and morphological characteristics in the mouse brain are described using the Nissl data found in the Allen Reference Atlas.

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Key brainstem structures activated during hypoxic exposure in one-day-old mice highlight characteristics for modelling breathing network in premature infants

Frontiers in Physiology, 2016
We mapped and characterized changes in the activity of brainstem cell groups under hypoxia in one-day-old newborn mice, an animal model in which the central nervous system at birth is particularly immature.

The basal ganglia and the epilepsies

Epilepsia Open, EarlyView.
Abstract The basal ganglia are an evolutionarily conserved neural circuit best known for the selection and sequencing of voluntary movement. Increasing evidence, however, indicates that these structures also play an important role in regulating pathological brain states, including seizures.

Regulation of motivation for food by neuromedin U in the paraventricular nucleus and the dorsal raphe nucleus [PDF]

International Journal of Obesity, 2016
Motivation for high-fat food is thought to contribute to excess caloric intake in obese individuals. A novel regulator of motivation for food may be neuromedin U (NMU), a highly-conserved neuropeptide that influences food intake. Although these effects of NMU have primarily been attributed to signaling in the paraventricular nucleus of the hypothalamus
