Critical slowing down governs the transition to neuron ~ Critical slowing down near the transition to spiking in biological neurons Using the whole-cell patch con guration and acute slices prepared from 2-4 week old rats, we recorded intracellularly the membrane potential of cortical pyramidal neurons and fast-spiking interneurons in response to current injections.
Critical Slowing Down Governs the Transition to Neuron Spiking ~ The existence of critical slowing down is a direct consequence of a bifurcation underlying the transition from quiescence to spiking in neurons [6, 7, 25, 26].Although there have been experimental reports of changes in subthreshold activity dependent on the level of depolarization in cortical neurons, such as the width and decay of exitatory postsynaptic potentials (EPSPs) [12, 27, 28] or the .

1Critical slowing down governs the transition to neuron ~ The dynamical system approach has identified two robust mechanisms for the transition from subthreshold activity to spiking, saddle-node and Hopf bifurcation. Although theory provides precise predictions on signatures of critical slowing down near the bifurcation to spiking, quantitative experimental evidence has been lacking.

No evidence for critical slowing down prior to human ~ There is an ongoing debate whether generic early warning signals for critical transitions exist that can be applied across diverse systems. The human epileptic brain is often considered as a prototypical system, given the devastating and, at times, even life-threatening nature of the extreme event epileptic seizure.
Burst Spiking of a Single Cortical Neuron Modifies Global ~ Repetitive burst spiking of the patched neuron caused a switch into the UP/DOWN state, with bimodal E m distribution and high-amplitude, slow LFP deflections that lasted for >20 min. But in another example of burst-induced switch from the persistent-UP to UP/DOWN state ( Fig. 3, D and E ), the cortex spontaneously reverted to the persistent-UP .
Neuronal metabolism governs cortical network response ~ (A) Raster plot of spiking in a network of 100 neurons showing slow rhythmic transitions between up and down phases synchronously throughout the network. Each neuron was coupled into an excitatory network by EPSPs with decay time constant of 100 ms, and each neuron had gK ATP. Each dot corresponds to one action potential.
Seizures Start without Common Signatures of Critical ~ In the present study, we review briefly the general characteristics that have been observed in systems prior to critical transitions and apply these general indicators to nearly 300 epileptic seizures collected from human subjects using invasive EEG. Only in about 8% of the patients was evidence of critical transitions found.

Spiking Neuron - an overview / ScienceDirect Topics ~ Wim van Drongelen, in Signal Processing for Neuroscientists (Second Edition), 2018. 25.6 Analyzing Spiking Neurons Stimulated With Noise. When studying intracellular or extracellular recordings of a spiking neuron while stimulating it with noise, one might (of course) use the raw output trace (including the action potentials) and relate this to the input as we have done previously (Fig. 25.3).
Simple Model of Spiking Neurons - Izhikevich ~ • FS (fast spiking) neurons can fire periodic trains of action poten-tials with extremely high frequency practically without any adap-tation (slowing down), as one can see in Fig. 2FS. In the model, this corresponds to a =0 : 1 (fast recovery). • LTS (low-threshold spiking)neurons can also fire high-frequency
neuroscience - Why has evolution made neurons use spiking ~ Once the "threshold voltage" is reached, the neuron lights up and fires. This is how "decisions" are made by neurons: inputs from many inhibitory and excitatory neurons are summed, and if the sum is above the threshold voltage, the neuron in question fires. To use computational language, a neuron is a logic AND gate with hundreds of inputs.
Differential Activation of Fast-Spiking and Regular-Firing ~ Relationship between fast-spiking inhibitory neuron firing with task stimuli and movement. (A) Raster plot (top) and PETH (bottom) of an example fast-spiking, putative inhibitory neuron. Across all trials, firing rates increased following presentation of the auditory, decision-cue (central axis), and activity was sustained for longer than 1 s.
