Adenosine receptors are the on‐and‐off switch of astrocytic cannabinoid type 1 (CB1) receptor effect upon synaptic plasticity in the medial prefrontal cortex

open access: yesGlia, Volume 72, Issue 6, Page 1096-1116, June 2024.
Main Points CB1R heteromerizes with A1R and A2AR in astrocytes. CB1R signaling is potentiated by A1R and inhibited by A2AR. LTP potentiation by CB1R is A1R‐dependent in IP3R2WT mice. CB1R activation and A2AR blockade decrease LTP independently in IP3R2KO mice.

Solution and Error Analysis of Two Dimensional Fredholm-Volterra Integral Equations Using Piecewise Constant Functions

open access: yesAmerican Journal of Computational and Applied Mathematics, 2012
In this paper, the piecewise constant Block-Pulse functions and their operational matrices of integration have directly been used to solve a two-dimensional Fredholm-Volterra integral equation of second kind. This method presents a computational technique through converting this integral equation into a system of linear equations which can be easily ...

Numerical solution for Fredholm–Volterra integral equation of the second kind by using collocation and Galerkin methods

open access: yesJournal of King Saud University - Science, 2010
AbstractThe Fredholm–Volterra integral equation of the second kind with continuous kernels with respect to position and time, is solved numerically, using the Collocation and Galerkin methods. Also the error, in each case, is estimated.
