Kryptonite,
You can start learning neural network by studying the fundamental of Neural Network by Fausett. You can download this at rapidshare.com/files/9626743/Laurene_Fausett_-_Fundamentals_Of_Neural_Networks.pdf
After you study this, you can look for another book which has more detailed information. I don't have the softcopy of this book and also don't know where can download. You can refer to this site, **broken link removed**
There are sample matlab code of neural network as well. This book is good for advance learner, as there is matlab code together with explanation.
