A Mathematical Model of a Neuron with Synapses based on Physiology [PDF]

, 2008
The neuron, when considered as a signal processing device, itsinputs are the frequency of pulses received at the synapses, and its output is the frequency of action potentials generated- in essence, a neuron is a pulse frequency signal processing device.

Locus Coeruleus Noradrenergic‐Spinal Projections Contribute to Electroacupuncture‐Mediated Antinociception in Postoperative Pain in Mice

Advanced Science, EarlyView.
How locus coeruleus noradrenergic‐spinal projections and subsequent α2A adrenoceptors‐CaMKII signaling cascades contribute to electroacupuncture‐induced antinociception in postoperative pain in mice is described. Abstract Postoperative pain remains a significant challenge in healthcare.

Implementing Multimodal Hardware Security with 2D α‐In2Se3 Ferroelectric Transistor

Advanced Science, EarlyView.
A multimodal secure transistor‐integrated in‐memory sensing and computing architecture is demonstrated by leveraging its electronic and optoelectronic synaptic behaviors. Key security primitives, such as anticounterfeiting, watermarking, logic locking, and camouflaging, are implemented within a compact single‐transistor structure, providing a scalable ...

Membrane potential states gate synaptic consolidation in human neocortical tissue. [PDF]

Nat Commun
Synaptic mechanisms that contribute to human memory consolidation remain largely unexplored. Consolidation critically relies on sleep. During slow wave sleep, neurons exhibit characteristic membrane potential oscillations known as UP and DOWN states ...

Mixed‐Dimensional Floating Gate Phototransistors for Mixed‐Modal In‐Sensor Reservoir Computing

Advanced Science, EarlyView.
Designing bio‐inspired multisensory neuromorphic devices holds significant importance for low‐power and high‐efficiency computing. Here, the authors introduce a floating‐gate phototransistor based on the mixed‐dimensional heterostructure of 0D‐CsPbBr3 QDs and 2D‐MoS2 few layers.

Changing the responses of cortical neurons from sub- to suprathreshold using single spikes in vivo

eLife, 2013
Action Potential (APs) patterns of sensory cortex neurons encode a variety of stimulus features, but how can a neuron change the feature to which it responds?

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

Advanced 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

Concurrent validity of dynamic bedside quantitative sensory testing paradigms in breast cancer survivors with persistent pain

Scandinavian Journal of Pain
Studies on the concurrent validity of clinically applicable testing protocols for conditioned pain modulation (CPM) and temporal summation of pain (TSP) in breast cancer survivors (BCS) with persistent pain are lacking.
