Regional response to light illuminance across the human hypothalamus

eLife
Light exerts multiple non-image-forming biological effects on physiology including the stimulation of alertness and cognition. However, the subcortical circuitry underlying the stimulating impact of light is not established in humans.

Hypothalamus-hippocampus circuitry regulates impulsivity via melanin-concentrating hormone

Nature Communications, 2019
Impulsive behaviour is common in various neuropsychiatric disorders. Here, the authors identify a pathway from the lateral hypothalamus to the ventral hippocampus and the role of melanin-concentrating hormone signaling in these neurons in specifically ...

Lateral hypothalamus as a sensor-regulator in respiratory and metabolic control

Physiology and Behavior, 2013
Physiological fluctuations in the levels of hormones, nutrients, and gasses are sensed in parallel by interacting control systems distributed throughout the brain and body.

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 ...

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Lateral Hypothalamic Control of the Ventral Tegmental Area: Reward Evaluation and the Driving of Motivated Behavior

Frontiers in Systems Neuroscience, 2017
The lateral hypothalamus (LH) plays an important role in many motivated behaviors, sleep-wake states, food intake, drug-seeking, energy balance, etc.

Control of serotonergic neurons in the dorsal raphe nucleus by the lateral hypothalamus

, 2002
Anatomical evidence indicates the presence of projections from the lateral hypothalamus to serotonergic (5-hydroxytryptamine, 5-HT) neurons of the dorsal raphe nucleus (DR).

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.

Hypovolemic hemorrhage induces Fos expression in the rat hypothalamus: Evidence for involvement of the lateral hypothalamus in the decompensatory phase of hemorrhage

, 2016
This study tested the hypothesis that the hypothalamus participates in the decompensatory phase of hemorrhage by measuring Fos immunoreactivity and by inhibiting neuronal activity in selected hypothalamic nuclei with lidocaine or cobalt chloride ...

Early neurocognitive outcomes following SEEG with radiofrequency thermocoagulation

Epilepsia Open, EarlyView.
Abstract Objective Characterization of early neuropsychological outcomes following SEEG with radiofrequency thermocoagulation (RFTHC) is essential to guide patient expectations around return to work, study, and caregiving. The current study aimed to describe the early neurocognitive sequelae of SEEG.
