Neural networks in Lisp - advice -

can suggest tutorial or book neural networks in lisp, or blog, or share code sample?

i have experience neural netowrks in imperative languages c++, java, c#, want try in lisp.

the seminal book ai: modern approach includes lisp source code on website: link specifically, check out learning chapter (perceptron etc)

in same vein have paradigms of ai in lisp, doesn't touch neural networks if remember correctly.
