Characterization of excitatory synaptic transmission in the anterior cingulate cortex of adult tree shrew

open access: yesMolecular Brain, 2017
The tree shrew, as a primate-like animal model, has been used for studying high brain functions such as social emotion and spatial learning memory. However, little is known about the excitatory synaptic transmission in cortical brain areas of the tree ...

CMOS circuit implementations for neuron models [PDF]

open access: yes, 1990
The mathematical neuron basic cells used as basic cells in popular neural network architectures and algorithms are discussed. The most popular neuron models (without training) used in neural network architectures and algorithms (NNA) are considered ...

An artificial sensory neuron with visual-haptic fusion

open access: yesNature Communications, 2020
Human behaviors are extremely sophisticated, relying on the adaptive, plastic and event-driven network of sensory neurons. Such neuronal system analyzes multiple sensory cues efficiently to establish accurate depiction of the environment.

C9orf72-ALS human iPSC microglia are pro-inflammatory and toxic to co-cultured motor neurons via MMP9

open access: yesNature Communications, 2023
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive motor neuron loss, with additional pathophysiological involvement of non-neuronal cells such as microglia.

Hopf Bifurcation and Chaos in Tabu Learning Neuron Models [PDF]

open access: yes, 2004
In this paper, we consider the nonlinear dynamical behaviors of some tabu leaning neuron models. We first consider a tabu learning single neuron model. By choosing the memory decay rate as a bifurcation parameter, we prove that Hopf bifurcation occurs in

Microvascular decompression for hemifacial spasm: a review of twenty-one operated cases

open access: yesThe Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2020
Background Microvascular decompression of facial nerve provides definitive and long-term cure for hemifacial spasm. We review our experience of treating hemifacial spasm by microvascular decompression.

Microglia clear neuron-released α-synuclein via selective autophagy and prevent neurodegeneration

open access: yesNature Communications, 2019
Microglia maintain brain homeostasis by removing neuron-derived components such as myelin and cell debris. The evidence linking microglia to neurodegenerative diseases is growing; however, the precise mechanisms remain poorly understood.

An Adaptive Locally Connected Neuron Model: Focusing Neuron

open access: yes, 2020
This paper presents a new artificial neuron model capable of learning its receptive field in the topological domain of inputs. The model provides adaptive and differentiable local connectivity (plasticity) applicable to any domain.

Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex [PDF]

open access: yes, 2015
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables.
