Sentence examples for spike precision from inspiring English sources

By investigating the CA3 PC rate-driven input output function of CA1 PC using in vitro electrophysiology, in vitro-simulation of inhibitory network, and in silico computational modeling, we demonstrated for the first time that GABAA receptor-mediated FF and FB inhibition differentially modulate the gain, the spike precision, the neural code transformation and the information capacity of CA1 PC.

They also show more realistic rate-level functions for pure tones, ISIHs, first spike precision and even two-tone facilitation (although not shown here).

Fast, subthreshold fluctuations in the intracellular membrane potential have been shown to translate into precisely timed action potentials (Bryant and Segundo, 1976; Mainen and Sejnowski, 1995) and that such spike precision carries information about the input (Cecchi et al., 2000).

(H ) Schematic showing mean firing rates over time for input neurons with σ = 40 ms used for calculating I. (I ) Average difference in membrane potential when the input spike precision is ∼40 ms. (J ) Transfer of plasticity to a neighboring stimulus position when a subpopulation of synapses and timing are shared (red) compared to membrane potential difference from (I, black).

Diminished inhibitory transmission may also contribute to temporal jitter to acoustic cues; for example, both the excitatory synaptic and spike precision are compromised at auditory nerve bushy cell synapses in the cochlear nucleus of early-onset hearing-impaired mice (Wang and Manis 2005).

(E ) Schematic showing mean firing rates over time for input neurons with σ = 5 ms used for calculating F. (F ) Average difference in membrane potential when the input spike precision is ∼5 ms (individual simulations grey, mean red) compared to a theoretical curve.

An attractor, yielding a stable spiking precision in the (sub millisecond range, governs the dynamics of synchronization.

Interestingly, different combinations of synaptic weights optimized either first-spike timing precision or spike number, efficiently controlling transmission and filtering properties.

Neither in vivo l-DOPA nor cocaine treatment significantly altered the basal spike-frequency or spike-timing precision (coefficient of variation of the interspike interval) of juvenile or adult substantia nigra dopamine pacemaker (Fig. 2C and D, and Supplementary Table 5).

The above findings, highlighting the importance of spike time precision from an evolutionary point of view, raise several questions concerning their generative source, the way the time precision is read out, and the causes that make this computational element so frequent in the model.

In this framework, an examination of axon tract composition can yield insights into neural circuit function in regard to energetics, processing speed, spike timing precision, and average rates of neural activity.
