This paper presents an in-depth theoretical analysis of the orientation selectivity properties of simple cells and complex cells, that can be well modelled by the generalized Gaussian derivative model for visual receptive fields, with the p...

To model the dynamics of neuron membrane excitability many models can be considered, from the most biophysically detailed to the highest level of phenomenological description. Recent works at the single neuron level have shown the importanc...
Self-supervised learning of scale-invariant neural representations of space and time [0.03%]

Hippocampal representations of space and time seem to share a common coding scheme characterized by neurons with bell-shaped tuning curves called place and time cells. The properties of the tuning curves are consistent with Weber's law, suc...
Neuronal traveling waves form preferred pathways using synaptic plasticity [0.03%]

Traveling waves of neuronal spiking activity are commonly observed across the brain, but their intrinsic function is still a matter of investigation. Experiments suggest that they may be valuable in the consolidation of memory or learning, ...

Childhood absence epilepsy (CAE) is a paediatric generalized epilepsy disorder with a confounding feature of resolving in adolescence in a majority of cases. In this study, we modelled how the small-scale (synapse-level) effect of progester...
Effects of dendritic Ca2+ spike on the modulation of spike timing with transcranial direct current stimulation in cortical pyramidal neurons [0.03%]
顶叶直流电刺激介导的树突Ca2+ spikes对锥体神经元尖峰时间调控的影响研究

Xuelin Huang et al.
Transcranial direct current stimulation (tDCS) generates a weak electric field (EF) within the brain, which induces opposite polarization in the soma and distal dendrite of cortical pyramidal neurons. The somatic polarization directly affec...
How plasticity shapes the formation of neuronal assemblies driven by oscillatory and stochastic inputs [0.03%]
可塑性如何塑造由振荡和随机输入驱动的神经元簇的形成

Synaptic connections in neuronal circuits are modulated by pre- and post-synaptic spiking activity. Previous theoretical work has studied how such Hebbian plasticity rules shape network connectivity when firing rates are constant, or slowly...
Effect of burst spikes on linear and nonlinear signal transmission in spiking neurons [0.03%]
爆发尖峰对神经元线性及非线性信号传输的影响

Maria Schlungbaum et al.
We study the impact of bursts on spike statistics and neural signal transmission. We propose a stochastic burst algorithm that is applied to a burst-free spike train and adds a random number of temporally-jittered burst spikes to each spike...
