Pacing Spikes All Over
Ventricular safety pacing (VSP) is used to avoid cross talk by delivering ventricular stimulus shortly after an atrial-paced event if ventricular-sensed event occurs. Although VSP is a protective feature that exists for decades in different pacing devices, there are some reports of unfavorable outcomes of this algorithm. More so, health care providers sometimes face difficulties in interpreting...
متن کاملComputation with Spikes in a Winner-Take-All Network
The winner-take-all (WTA) computation in networks of recurrently connected neurons is an important decision element of many models of cortical processing. However, analytical studies of the WTA performance in recurrent networks have generally addressed rate-based models. Very few have addressed networks of spiking neurons, which are relevant for understanding the biological networks themselves ...
متن کاملBristling all over
They are runners-up in the Current Biology photomicrography competition. During normal development of the nervous system in Drosophila, a process called 'lateral inhibition' ensures that only a single neural precursor is selected from a group of initially equipotent cells. Where lateral inhibition fails, excess neural cells develop, as shown in the image above, where a 'tuft' of thorn-like bris...
متن کاملOn the unique representability of spikes over prime fields
For an integer n ≥ 3, a rank-n matroid is called an n-spike if it consists of n three-point lines through a common point such that, for all k ∈ {1, 2, . . . , n− 1}, the union of every set of k of these lines has rank k + 1. Spikes are very special and important in matroid theory. Wu [13] found the exact numbers of n-spikes over fields with 2, 3, 4, 5, 7 elements, and the asymptotic values for ...
