DefinitionA technique that records neural activity in many places in parallel, generally using light.Activity patterns can be visualized as images that reflect both anatomy in space and activity in time.Subtechniques include optical imaging (e.g. using intrinsic signals or voltage sensitive dyes), calcium imaging (using fluorescent dyes, lI>ratiometric dyes, measure of I>-deltaFIF), and functional magnetic resonance tomography (fMRT), among others. Characteristics Imagjng TechniquesBrains consist of a high number of neurons that are interconnected and work as an ensemble.For example, the human brain has IQ billion neurons, and even the brain of a humble honeybee has I million neurons.Understanding their function requires recording from these neurons under physiologically controlled conditions.Single-cell electrophysiology gives information about neural activity in individual cells as a whole.Functional imaging techniques have been developed in order to record neural activity both in space and in time simultaneously.Space can include the analysis of activity along the branching pattern of a single neuron, or across large neuron populations.As a consequence, functional imaging has gained an important role in understanding the relationship between the morphology of neurons and their function, and in understanding combinatorial information processing in the brain.In the following, I will review the major techniques that have been used in recent years, first from the point of view of the signal that is measured (intrinsic signals, dyes, reporter proteins), next from the point of view of the neurons measured (from single neurons to entire brains), including examples from the analysis of olfactory systems.

Functional imaging methodology has revolutionized our ability to understand brain-behavior relationships. In contrast with the static images obtained with standard imaging methods, functional images permit us to track brain activity as humans view stimuli, hear sounds, consider choices, and make decisions. The insights now possible because of this technology have not only provided new potential markers for disease but have also permitted questions of neural mechanism to be addressed in living humans. Because of the breadth and depth of research that directly or tangentially touches upon functional imaging, it is impossible to do justice to the various subfields, analysis streams, and methodological complexities in one chapter. Instead, this chapter will provide a brief overview of the underlying conceptual framework, basic analytic techniques, and details of the imaging methodologies available for the acquisition of functional imaging data.
