Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling

open access: yesAdvanced Science, EarlyView.
The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

Molecular Specialization of GABAergic Synapses on the Soma and Axon in Cortical and Hippocampal Circuit Function and Dysfunction

open access: yesFrontiers in Molecular Neuroscience, 2019
The diversity of inhibitory interneurons allows for the coordination and modulation of excitatory principal cell firing. Interneurons that release GABA (γ-aminobutyric acid) onto the soma and axon exert powerful control by virtue of proximity to the site

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

PRMT3‐Mediated H4R3me2a Promotes Primary Age‐Related Tauopathy by Driving Tau Hyperphosphorylation in Neuron

open access: yesAdvanced Science, EarlyView.
This study identifies PRMT3‐mediated H4R3me2a as a critical driver of tau hyperphosphorylation in primary age‐related tauopathy. Mechanistic insights reveal that the PRMT3/H4R3me2a/miR‐448 axis suppresses IGF1R expression via epigenetic regulation, further dysregulating the PI3K/AKT/GSK3β pathway.

Melatonin Modulates the GABAergic Response in Cultured Rat Hippocampal Neurons

open access: yesJournal of Pharmacological Sciences, 2012
In the present study, we investigated the effect of melatonin on the GABA-induced current (IGABA) and GABAergic miniature inhibitory postsynaptic currents (mIPSCs) in cultured rat hippocampal neurons using the whole-cell patch-clamp technique.

A Markovian event-based framework for stochastic spiking neural networks

open access: yes, 2011
In spiking neural networks, the information is conveyed by the spike times, that depend on the intrinsic dynamics of each neuron, the input they receive and on the connections between neurons. In this article we study the Markovian nature of the sequence

Capturing the Electrical Activity of all Cortical Neurons: Are Solutions Within Reach?

open access: yesAdvanced Science, EarlyView.
Despite advancements in implantable electrode technology, challenges persist in scaling up these devices to record most of the neuronal activity across the cortex. This review explores the limitations of both rigid and flexible probes, including tissue damage and foreign body response, while also discussing emerging biohybrid strategies.
