This type of reset is commonly seen in fast spiking interneurons (Bean 2007), and corresponds to a low value of the voltage reset V r, combined with a weak spike-triggered adaptation b.
IO stimulation evoked a weak post-complex spike facilitation of simple spike output (the facilitation was +43% +/−6%(mean+/−sem, N = 14 cells) so the amount of PC inhibition would actually increase at the time of the DCN cell rebound response.
For the systemic inhibitory manipulations, there was a weak anticorrelation between spike rate and population coupling (ρ = − 0.17, p < 10 5).
When a neuron is about to emit a spike, even a weak electric field can bias spike threshold.
Similar but slightly weaker spike patterns were observed in New York City, Washington and Chicago over the same time (in UTC).
We observe similar, though slightly weaker, spike patterns in all three cities, where the first peaks on April 15 have a six- to eight-hour delay compared with the first peak in Boston.
By comparison, calcium responses to 1 or 300 nM DF3 typically exhibited a weak or absent initial spike, followed by oscillations that return almost to baseline in the intervals.
In this study, we inspected two simple and abstract models for the effect of a weak noise on neural spikes and its consequences on signal transmission by neural populations.
Samples were then extracted with dichloromethane:methanol, passed through a weak anion exchange cartridge, spiked with internal standard, and analyzed by gas chromatography/mass spectrometry in the full scan mode.
A weak housing market and a spike in payment defaults scared investors away from mortgage debt, including bonds and other securities backed by home loans.
An aliquot of each extracted DNA specimen was spiked with a weak dilution of C. trachomatis DNA and amplified by PCR to exclude such inhibitors.
