Understanding information processing done within a neural network is complicated. Its believed that to perform even the simplest task, numerous neurons are involved. One of the biggest challenges, which lie in the heart of this complication, is recording the spatiotemporal pattern of the neural activity from numerous neurons simultaneously. This book presents a method that allows to perform high speed imaging using two-photon laser scanning microscopy combined with calcium dyes. Performing neural imaging using this method results in an excellent spatial resolution and a high temporal...
