Summary: This study presents a biologically-plausible computational model that demonstrates the crucial role of hippocampal-thalamic-cortical activity in systems consolidation. The model provides testable predictions for experimental neuroscience and sheds new light on the mechanisms of memory engram reorganization and associated pathways.

Summary: Studies have shown that ApoE2 and ApoE3 can significantly attenuate H2O2-induced neuronal apoptosis, while ApoE4 has no neuroprotective effect and may even have a toxic effect. ApoE2 and ApoE3 regulate the Akt/FoxO3a/Bim signaling pathway in the presence of H2O2 to exert their effects.

Summary: This study has shown that CPT1C can mitigate Aβ(25-35)-induced oxidative stress, apoptosis, and accumulation of AD marker proteins in hippocampal neurons, suggesting that CPT1C has beneficial effects in alleviating AD and is involved in PPARα activation.

Summary: The brain is a complex organ composed of billions of neurons. Its structure, which exhibits a modular topological organization, is influenced by network heterogeneity and the topological properties of the underlying connectivity. This study explores the functional and structural connections between interconnected subpopulations of cortical and hippocampal neurons, and their impact on the patterns of electrophysiological activity. The results reveal the differences in connectivity and activity patterns between the two types of neurons, and the influence of the physical environment on the development and maturation of neuronal networks.

Summary: This study explores the pathogenesis of neuritic plaques, finding that accumulations of iron and ferroptosis in the central nervous system trigger the formation of plaques. Microglial ferritin expression and A beta deposition both contribute to this process. Neurofibrillary tangles, on the other hand, are unlikely to involve the release of neuronal iron extracellularly.

Summary: The present study investigated the effects of low-frequency electrical stimulation on cortical and hippocampal networks. The results showed that cortical assemblies were more reactive than hippocampal ones, and that the response to stimulation was delayed in the cortical assemblies.

Summary: The study demonstrated that oxytocin can prevent the damage to rat hippocampal neurons induced by methamphetamine, including protection of mitochondrial membrane potential, reduction of oxidative stress, and inhibition of neuron apoptosis.

Summary: This study reveals the underlying mechanisms of anesthesia-induced remote memory impairment and identifies the hyperactivity of pyramidal neurons and increased tau phosphorylation as significant factors. Inhibiting these abnormal activities may improve memory recall in individuals with Alzheimer's disease after anesthesia.

Summary: The protein PCBP2 has been shown to directly bind to the 5' terminus of p53 mRNA and is involved in both stability and translation control of p53 mRNA, especially under stress conditions. This dual function factor plays a crucial role in modulating p53 expression.

Summary: The influence of cannabidiol (CBD) on brain development is not well understood, but it may interfere with the endogenous cannabinoid system during critical periods, leading to apoptosis and necroptosis in neurons and astrocytes.

Summary: This study explores the role of the CREB1/DAPK1 axis in brain injury after CPR. Overexpression of CREB1 improves rat neurological function, inhibits neuron apoptosis, and reduces Caspase-3 expression. CREB1 suppresses hippocampal neuron apoptosis by inhibiting DAPK1 expression. Therefore, CREB1 can mitigate brain injury after CPR.
