Long-Term Recording of LTP in Cultured Hippocampal Slices
Long-term potentiation (LTP) was elicited by high frequency stimulation in hippocampal slices cultured on multi-electrode arrays. LTP lasting more than 1 h was recorded in 75% of slices, and a significant number of slices exhibited a non-decaying LTP ...

This study identifies DEC2 as a critical transcriptional repressor of Scn2a that directly binds E‐box motifs in its promoter to regulate neuronal plasticity and epileptogenesis. Functional manipulation of DEC2 alters seizure susceptibility in vivo. Cannabidiol enhances this repression, unveiling a novel DEC2‐SCN2A axis underlying its anticonvulsant ...

The malleable brain: plasticity of neural circuits and behavior: A review from students to students [PDF]
One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic ...

NMDA and AMPA receptors are co-localized at most glutamatergic synapses, where their numbers and distribution undergo dynamic changes. Glutamate binds to both the NMDA and AMPA receptors.

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.

Epigenetic Regulation of DAPK1 and Netrin‐1 Drives Diabetic Encephalopathy
This study identifies a microRNA (miR)‐216a‐5p/death‐associated protein kinase 1 (DAPK1)/hepatocyte nuclear factor 1 homeobox A (HNF1A)/Netrin‐1 signaling axis in diabetic encephalopathy (DE). In leptin receptor‐deficient (db/db) and streptozotocin (STZ)‐induced diabetic mice, reduced miR‐216a‐5p increases DAPK1 expression, disrupting HNF1A binding to ...

Inactivation of presenilins causes pre-synaptic impairment prior to post-synaptic dysfunction [PDF]
Synaptic dysfunction is widely thought to be a pathogenic precursor to neurodegeneration in Alzheimer’s disease (AD), and the extent of synaptic loss provides the best correlate for the severity of dementia in AD patients.

Developmental Effects of Melatonin on Synaptic Plasticity of Hippocampal CA1 Neurons in Visual Deprived Rats [PDF]
Background & Aims: Change in visual experience impairs circadian rhythms. In this study, The effects of visual deprivation during critical period of brain development and melatonin intake on synaptic plasticity of hippocampal CA1 neurons were evaluated ...

SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.
