Different coding characteristics between flight and freezing in dorsal periaqueductal gray of mice during exposure to innate threats

open access: yesAnimal Models and Experimental Medicine, Volume 5, Issue 6, Page 491-501, December 2022., 2022
Flight and freezing are two vital defensive behaviors in the process of avoiding natural enemies in mice. We investigated the neural activity in dPAG nuclei of mice under two defensive behaviors, and found different coding features between flight and freezing behaviors. Abstract Background Flight and freezing are two vital defensive behaviors that mice

Accumulation of Damaging Lipids in the Arf1‐Ablated Neurons Promotes Neurodegeneration through Releasing mtDNA and Activating Inflammatory Pathways in Microglia

open access: yesAdvanced Science, EarlyView.
Arf1 defects activate the AKT‐mTORC1‐SREBP1‐FASN pathway to increase lipid synthesis and disrupt ER‐mitochondrial‐lysosomal homeostasis in neurons. Impaired mitochondria secrete damaged mtDNA via mitochondria‐derived extracellular vesicles, which is phagocytosed by the microglia and activated inflammation signaling.

The role of nitric oxide in the dorsomedial periaqueductal gray (dmPAG) column in cardiovascular responses in urethane‐anesthetized male rats

open access: yesAnimal Models and Experimental Medicine, Volume 5, Issue 6, Page 557-564, December 2022., 2022
In the current study, after anesthetized rat with urethan the femoral artery was cannulated, then its head was mounted on a stereotaxic instrument and drugs (saline‐NAME, L‐Arg, and L_Arg+ L‐NAME) microinjected into the dmPAG and cardiovascular responses that recorded by a Power lab were evaluated.

Altered Neural Activity in the Mesoaccumbens Pathway Underlies Impaired Social Reward Processing in Shank3‐Deficient Rats

open access: yesAdvanced Science, EarlyView.
This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...

Metabolomic and Cellular Mechanisms of Drug‐Induced Ototoxicity and Nephrotoxicity: Therapeutic Implications of Uric Acid Modulation

open access: yesAdvanced Science, EarlyView.
Drug‐induced renal damage impairs uric acid excretion, causing its accumulation in the serum, which subsequently infiltrates the cochlea. Xanthine oxidase and the ABCG2 transporter, critical in uric acid metabolism and excretion, undergo pathological changes in renal tubular and cochlear stria vascularis cells.

Silicon Enhances Functional Mitochondrial Transfer to Improve Neurovascularization in Diabetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
These findings reveal that silicon exerts strong protective effects in diabetic bone defect models by selectively promoting Drp1‐Mff activity. Silicon facilitates precise regulation of mitochondrial dynamics to enable functional mitochondrial transfer.

Multi‐Shank 1024 Channels Active SiNAPS Probe for Large Multi‐Regional Topographical Electrophysiological Mapping of Neural Dynamics

open access: yesAdvanced Science, EarlyView.
This research article introduces a novel CMOS neural probe with 1024 channels distributed across eight shanks. The SiNAPS probe allows for the simultaneous recording of both local field potentials and action potentials in large brain areas. The probe's design allows for detailed mapping and linking neural dynamics and population unit activity, as ...
