Differential recruitment of ventral pallidal e-types by behaviorally salient stimuli during Pavlovian conditioning

iScience, 2021
Summary: The ventral pallidum (VP) is interfacing striatopallidal and limbic circuits, conveying information about salience and valence crucial to adjusting behavior.

Remote cortical perturbation dynamically changes the network solutions to given tactile inputs in neocortical neurons

iScience, 2022
Summary: The neocortex has a globally encompassing network structure, which for each given input constrains the possible combinations of neuronal activations across it. Hence, its network contains solutions.

Glucokinase neurons of the paraventricular nucleus of the thalamus sense glucose and decrease food consumption

iScience, 2021
Summary: The paraventricular nucleus of the thalamus (PVT) controls goal-oriented behavior through its connections to the nucleus accumbens (NAc). We previously characterized Glut2aPVT neurons that are activated by hypoglycemia, and which increase ...

Intracellular Ca2+ dynamics in the ALA neuron reflect sleep pressure and regulate sleep in Caenorhabditis elegans

iScience, 2022
Summary: The mechanisms underlying sleep homeostasis are poorly understood. The nematode Caenorhabditis elegans exhibits 2 types of sleep: lethargus, or developmentally timed, and stress-induced sleep.

Anatomical organization of temporally correlated neural calcium activity in the hippocampal CA1 region

iScience, 2023
Summary: Hippocampal CA1 neuronal ensembles generate sequential patterns of firing activity that contribute to episodic memory formation and spatial cognition. Here we used in vivo calcium imaging to record neural ensemble activities in mouse hippocampal

Mu-opioid receptor selective superagonists produce prolonged respiratory depression

iScience, 2023
Summary: Synthetic opioids are increasingly challenging to combat the opioid epidemic and act primarily at opioid receptors, chiefly the G protein-coupled receptor (GPCR) μ-opioid receptor (MOR), which signals through G protein-dependent and β-arrestin ...

Casein kinase 1α is required to maintain murine hypothalamic pro-opiomelanocortin expression

iScience, 2023
Summary: Hypothalamic pro-opiomelanocortin (POMC) neuron development is considered to play an essential role in the development of obesity. However, the underlying mechanisms remain unclear.

Ablation of Ventral Midbrain/Pons GABA Neurons Induces Mania-like Behaviors with Altered Sleep Homeostasis and Dopamine D2R-mediated Sleep Reduction

iScience, 2020
Summary: Individuals with the neuropsychiatric disorder mania exhibit hyperactivity, elevated mood, and a decreased need for sleep. The brain areas and neuronal populations involved in mania-like behaviors, however, have not been elucidated.

Antidepressant Effects of (S)-Ketamine through a Reduction of Hyperpolarization-Activated Current Ih

iScience, 2020
Summary: Compelling evidence suggests that a single sub-anesthetic dose of (R,S)-ketamine exerts rapid and robust antidepressant effects. However, the cellular mechanisms underlying the antidepressant effects of (R,S)-ketamine remain unclear.
