Neuronal Communication: Firing Spikes with Spikes [PDF]

open access: yesCurrent Biology, 2012
Spikes of single cortical neurons can exert powerful effects even though most cortical synapses are too weak to fire postsynaptic neurons. A recent study combining single-cell stimulation with population imaging has visualized in vivo postsynaptic firing in genetically identified target cells.

Reinforcement learning in populations of spiking neurons [PDF]

open access: yes, 2008
Population coding is widely regarded as a key mechanism for achieving reliable behavioral responses in the face of neuronal variability. But in standard reinforcement learning a flip-side becomes apparent.

Prefrontal cortical activity predicts the occurrence of nonlocal hippocampal representations during spatial navigation.

open access: yesPLoS Biology, 2021
The receptive field of a neuron describes the regions of a stimulus space where the neuron is consistently active. Sparse spiking outside of the receptive field is often considered to be noise, rather than a reflection of information processing.

Complementarity of spike- and rate-based dynamics of neural systems [PDF]

open access: yes, 2012
Relationships between spiking-neuron and rate-based approaches to the dynamics of neural assemblies are explored by analyzing a model system that can be treated by both methods, with the rate-based method further averaged over multiple neurons to give a ...

Analysis of the Neuron Dynamics in Thalamic Reticular Nucleus by a Reduced Model

open access: yesFrontiers in Computational Neuroscience, 2021
Strategically located between the thalamus and the cortex, the inhibitory thalamic reticular nucleus (TRN) is a hub to regulate selective attention during wakefulness and control the thalamic and cortical oscillations during sleep.

On the Nonlearnability of a Single Spiking Neuron

open access: yesNeural Computation, 2005
We study the computational complexity of training a single spiking neuron N with binary coded inputs and output that, in addition to adaptive weights and a threshold, has adjustable synaptic delays. A synchronization technique is introduced so that the results concerning the nonlearn-ability of spiking neurons with binary delays are generalized to ...

Fractionally Predictive Spiking Neurons

open access: yesCoRR, 2010
Recent experimental work has suggested that the neural firing rate can be interpreted as a fractional derivative, at least when signal variation induces neural adaptation. Here, we show that the actual neural spike-train itself can be considered as the fractional derivative, provided that the neural signal is approximated by a sum of power-law kernels.
