Rapid surface accumulation of NMDA receptors increases glutamatergic excitation during status epilepticus

open access: yesNeurobiology of Disease, 2013
After 1 h of lithium-pilocarpine status epilepticus (SE), immunocytochemical labeling of NMDA receptor NR1 subunits reveals relocation of subunits from the interior to the cell surface of dentate gyrus granule cells and CA3 pyramidal cells ...

Role of Connexin 36 in Autoregulation of Oxytocin Neuronal Activity in Rat Supraoptic Nucleus

open access: yesASN Neuro, 2019
In the supraoptic nucleus (SON), the incidence of dye coupling among oxytocin (OT) neurons increases significantly in nursing mothers. However, the type(s) of connexin (Cx) involved is(are) unknown.

Persistent sodium current blockers can suppress seizures caused by loss of low‐threshold D‐type potassium currents: Predictions from an in silico study of Kv1 channel disorders

open access: yesEpilepsia Open, 2020
Objective Ion channels belonging to subfamily A of voltage‐gated potassium channels (Kv1) are highly expressed on axons, where they play a key role in determining resting membrane potential, in shaping action potentials, and in modulating action ...

Population rate coding in recurrent neuronal networks with undetermined-type neurons [PDF]

open access: yesarXiv, 2019
Neural coding is a key problem in neuroscience, which can promote people's understanding of the mechanism that brain processes information. Among the classical theories of neural coding, the population rate coding has been studied widely in many works.

The Locus Coeruleus‐Periaqueductal Gray GABAergic Projection Regulates Comorbid Pain and Depression

open access: yesAdvanced Science, EarlyView.
LC‐GABA neurons exhibit elevated activity to noxious and aversive stimuli in chronic pain, and their activation alleviates pain‐ and depression‐like behaviors. While LC‐GABA neurons target LC‐NA neurons and GABA and Glu neurons in the vlPAG, they modulate the pain responses of LC‐NA neurons but regulate pain‐ and depression‐like behaviors through their

Unsupervised learning by a nonlinear network with Hebbian excitatory and anti-Hebbian inhibitory neurons [PDF]

open access: yesarXiv, 2018
This paper introduces a rate-based nonlinear neural network in which excitatory (E) neurons receive feedforward excitation from sensory (S) neurons, and inhibit each other through disynaptic pathways mediated by inhibitory (I) interneurons. Correlation-based plasticity of disynaptic inhibition serves to incompletely decorrelate E neuron activity ...

Electric Field‐Driven Conformational Changes in Molecular Memristor and Synaptic Behavior

open access: yesAdvanced Science, EarlyView.
Self‐assembled monolayers (SAMs) based molecular device is used for the emulation of synaptic functions. The device operates with a novel switching mechanism via incoherent charge transport, inducing conformational changes. With a low energy consumption (8.0 pJ µm−2), the system shows promise for neuromorphic computing, offering potential in low‐energy,

State-dependent cell-type-specific membrane potential dynamics and unitary synaptic inputs in awake mice

open access: yeseLife, 2018
The cellular and synaptic mechanisms driving cell-type-specific function during various cortical network activities and behaviors are poorly understood.

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.

Neural computation at the thermal limit [PDF]

open access: yesarXiv, 2014
Although several measurements and analyses support the idea that the brain is energy-optimized, there is one disturbing, contradictory observation: In theory, computation limited by thermal noise can occur as cheaply as ~$2.9\cdot 10^{-21}$ joules per bit (kTln2).
