Sentence examples for mediated by horizontal from inspiring English sources

In addition, inhibitory interactions mediated by horizontal cells and amacrine cells modulate the structure of the receptive field.

Therefore, surround information beyond the CRF is initially processed by fast connections which we consider to be feedback, whereas spatially tuned mechanisms are relatively slow and presumably mediated by horizontal connections.

Rather, this locus seems to have been under intense diversifying selection and subject to frequent exchanges mediated by horizontal transfer and recombination.

In particular, we look at recent advances in characterising excitatory-inhibitory balance as mediated by horizontal connections within visual cortex using dynamic causal modelling and neural fields.

We presented "target" and "surround" checkerboard mapping stimuli in both experiments to isolate feedback-receiving voxels and eliminate spill-over from feedforward-stimulated regions (e.g., mediated by horizontal interactions within V1) [ 14].

The presence of such strain-specific regions suggests that, in addition to gene loss mentioned earlier, gene acquisition events mediated by horizontal gene transfer (HGT) may have played a role during the evolution of the three species (see below).

We assume these are mediated by feedback and horizontal connections, respectively, but other factors may be involved.

It has been demonstrated that in the visual system surround effects are mediated by long range horizontal connections [59].

This antagonistic center-surround response is mediated by amacrine and horizontal cells (Figure 1), through a sign-reversing synapse to the cones often called feedback synapse, the global mechanism being called lateral inhibition [1] [3].

Our measurements with dopamine confirmed this: dopamine's effects on the spatial tuning of ganglion cells could not have been mediated by a change in horizontal cell coupling since dopamine led to the same shift in spatial tuning in Cx57-deficient mice as in wild type, at least under photopic conditions (Fig. 5).

This would seem to implicate weaker interactions between orientation detectors possibly mediated by abnormal long-range horizontal connectivity in V1.
