Are there any programmes to identify modular "NeuroBricks"?
Assuming that by "neurobricks" you imply the ability to design systems using modular neuronal components, then I think the Neurological Engineering Framework (NEF) and Nengo, the software used to leverage the NEF, is what you're looking for.

Essentially, groups of neurons fire together as a way to encode information from various sources. So you can get simple things like an integrator or something that keeps track of where to move a joystick (like in the research by Georgopolous), but that can scale up (because it's just a group of neurons) all the way to a complex model of the brain like Spaun.

In terms of engineering applications, there's a lot of things that these neurons are particularly good at, such as robotic arms, as shown in Spaun.
