Neuroscience textbook

 I am reading Kandel's neuroscience textbook.

It starts with an overview of the historical evolution of what we know about the brain. Two dichtomous ideas have shaped the evolution of our understanding of the brain. Are the different functions of the brain localized or do they act as a whole to produce behavior? These two views have shaped research on the brain throughout history. In the 1930's, finally, the experimental evidence for the localization of function became overwhelming through the work of Edgar Adroa, Wade Marshall and Philip Bard, who stimulated different parts of the cat body and measured neural responses in the cortex. 

 What does the future of neuroscience hold? Since I'm a compuational neuroscientist, I think that we will map the algorithms that the brain uses to solve the evolutionary problems it faces onto the activity of neural populations.  One enticing direction is to figure out how reinforcement learning algorithms map onto the neural dynamics of spiking neurons. Cells in the brain have computational roles. What could we discovered with the fine-grained experimental approaches that measure the activity of individual cells and attempt to figure out the models of the world and strategies for surviving in it that populations of neurons implement?
