Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance
Advanced Science, EarlyView.DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

Novel Roles for the Ectoenzyme CD38 in the Maintenance of Transcriptional and Metabolic Homeostasis in Astrocytes. [PDF]
GliaCD38 deficiency influences brain NAD/NAM metabolism. Global CD38 deficiency drives changes in astrocyte mitochondrial, metabolic, senescence, and neurodegenerative‐related genes. CD38 deficiency alters glial reactivity and astrocyte bioenergetics. ABSTRACT CD38 is an ectoenzyme that converts NAD+ to NAM to help maintain bioenergetic homeostasis.

Neural tube-ectoderm interactions are required for trigeminal placode formation [PDF]
, 1997 Cranial sensory ganglia in vertebrates develop from the ectodermal placodes, the neural crest, or both. Although much is known about the neural crest contribution to cranial ganglia, relatively little is known about how placode cells form, invaginate and

Logarithmic distributions prove that intrinsic learning is Hebbian
, 2017 In this paper, we present data for the lognormal distributions of spike rates, synaptic weights and intrinsic excitability (gain) for neurons in various brain areas, such as auditory or visual cortex, hippocampus, cerebellum, striatum, midbrain nuclei ...

Advanced Intelligent Systems, EarlyView.Natural fliers achieve remarkable aerial performance through diverse wing neuromechanical systems integrating actuation, sensing, and control. This study synthesizes neuromechanical architectures in insects and hummingbirds, identifying two key functional types‐Dual Neural‐Mechanical Oscillator and Neurally‐modulated Mechanical Oscillator‐ and ...

Animal Models and Experimental Medicine, EarlyView.The cumulative effect of EA analgesia is partially attributed to the activation of EA‐TRAPed cells in ACC. Multiple EA sessions and single EA sessions activated different neuronal populations in the ACC. The enhanced analgesic effect of multiple EA sessions may be attributed to an increase in the proportion of GABAergic neurons within the ACC. Abstract
