But even as Sandlock noted that he was "not excitable," his eyes brightened as he recalled an exhibition game at Yankee Stadium when he was with the Dodgers.
Although astrocytes are not excitable, recent findings indicate they may play a role in rapid signal transmission in the brain.
Notably, other thermographic phosphors are not excitable with red light.
This and many more refined versions of neural excitability to date contain four or more dynamic variables, but fortunately this is not essential for excitable systems.
Additionally, Zhang et al. (2006) demonstrated that endothelial cells can remain in the depolarized state for a long period until the electrical stimulus is removed, which is not consistent with excitable dynamics.
It promises to be quite a night and Di Matteo, who is not always the most excitable of characters, entered into the spirit of things by predicting "a hell of a match" and adding: "I hope our supporters are going to create the right atmosphere for us to perform at the highest level".
In short, this is not a safe haven: despite excitable claims the price could hit $10,000, where it goes next is anybody's guess, so investors should approach with caution.
While Taylor admits it is "hard to make programmes that will appeal to that broad an age group", she argues the channel does very well with shows such as Deadly 60 – whose mix of adventure with wildlife TV is a hit with those harder-to-reach boys – and takes heart from the fact that CBBC's target audience is "not cynical, but curious and excitable".
If your boss is remotely excitable, this is not a good idea, in case your "discovery" proves to be nothing but an artefact.
On the other hand, the action of DDT to induce typical cell stress responses among "non-excitable cells" is not directly mediated by any specific receptors; rather such actions of p,p′-DDT are likely to be mediated by its direct actions on cellular Ca2+ homeostasis (Younglai et al. 2004) and activation of cell stress responses including inflammation (Dutta et al. 2008).
