Prolonged prophylactic effects of gabapentin on status epilepticus-induced neocortical injury
Neurobiology of Disease, 2020 Long-term consequences of status epilepticus (SE) occur in a significant proportion of those who survive the acute episode. We developed an in vivo model of acute focal neocortical SE (FSE) to study long-term effects on local cortical structure and ...

Frontiers in Cellular Neuroscience, 2019 Intensity and frequency are the two main properties of sound. The non-monotonic neurons in the auditory system are thought to represent sound intensity. The central nucleus of the inferior colliculus (ICC), as an important information integration nucleus

A compact aVLSI conductance-based silicon neuron [PDF]
arXiv, 2015 We present an analogue Very Large Scale Integration (aVLSI) implementation that uses first-order lowpass filters to implement a conductance-based silicon neuron for high-speed neuromorphic systems. The aVLSI neuron consists of a soma (cell body) and a single synapse, which is capable of linearly summing both the excitatory and inhibitory postsynaptic ...

Random Walks for Spike-Timing Dependent Plasticity [PDF]
, 2003 Random walk methods are used to calculate the moments of negative image equilibrium distributions in synaptic weight dynamics governed by spike-timing dependent plasticity (STDP). The neural architecture of the model is based on the electrosensory lateral line lobe (ELL) of mormyrid electric fish, which forms a negative image of the reafferent signal ...

Associative memory model with long-tail-distributed Hebbian synaptic connections
Frontiers in Computational Neuroscience, 2013 The postsynaptic potentials of pyramidal neurons have a non-Gaussian amplitude distribution with a heavy tail in both hippocampus and neocortex. Such distributions of synaptic weights were recently shown to generate spontaneous internal noise optimal ...

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 ...

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.

A biophysical observation model for field potentials of networks of leaky integrate-and-fire neurons
, 2012 We present a biophysical approach for the coupling of neural network activity as resulting from proper dipole currents of cortical pyramidal neurons to the electric field in extracellular fluid.
