Sentence examples for surrounding stimulation from inspiring English sources

Thus, the apparent brightness of a stimulus depends not only on its own luminance but also on that of the surrounding stimulation.

SNr neurons are tonically active, firing at ∼10 40 Hz, thus to access which stimulation point evoked reliable spiking, spike traces were averaged over multiple (>3) trials, and voltage responses surrounding stimulation points were superimposed (A, upper).

Relative to wide-field stimulation or stimulation targeting axonal fibers, we reduced the maximal power of the laser using neutral density filters and performed calibration experiments to find intensities that would evoke precise, time-locked spikes in a small number of neurons with somatodendritic arbors surrounding the stimulation site.

By contrast, excitation during global motion and tonic excitation revealed by differential surround stimulation were unchanged.

We now turn to the question of whether the effects of attention and of surround stimulation on the neuronal activity were correlated.

In the presence of TTX, VG3-ACs depolarized to global motion as well as differential center motion, and hyperpolarizations observed during surround stimulation were abolished.

(2012), whereby attention and surround stimulation either used exactly the same mechanisms (single parameter model) or they were allowed to use separated mechanisms (two-parameter models).

Despite the opposite effects of attention and surround stimulation, their effect at the single cell level was still correlated, i.e. attentional MIs and surround MIs often showed a positive correlation.

So far we have investigated how the different tuning parameters are affected by surround stimulation and attention, and whether changes in a given parameter were correlated with changes in a different parameter.

Differential motion sensitivity of WG3-RGCs appears to be inherited from their excitatory input, which during center-only motion exceeds that observed during global motion nearly fivefold, and which is suppressed from tonic levels during isolated surround stimulation (n = 8, p < 0.003 for diff Ce vs global and vs diff Su ).

Fifteen cells were best described by a two-parameter additive normalization model (i.e. 71.4% of cells were best described by an additive model under conditions when the effect of surround stimulations is not part of the fitting routine).
