The animal brain is the most complex information processing system in any living organism. To understand how real nervous systems perform computations is one of the fundamental goals of neuroscience. Neural activation with stimulation should propagate through the neural circuits and induce behavioral responses. We want to understand how the environmental information is encoded in the neural activities and interacts with the internal states of the neural circuits. Measuring whole-brain activity and behavior will be important in revealing information processing mechanisms.
Animals move to their preferred environment based on the smells and sounds of their surroundings. Such navigation behaviors are suitable for clarifying the mechanism of information processing in neural circuits because the input-output relationship is clear: the organism senses the external environment, selects the necessary information, and outputs the processing result as a behavior (Fig. 1).
We use the nematode Caenorhabditis elegans in our research. The worms remember salt concentration at which they were cultivated with food, and they migrate to the region of the specific concentration in an environment with a salt concentration gradient. The neurons and their connections in the worm have been studied in detail (Fig. 2). However, even in the organism with the most extensive fundamental information in neuroscience, how each neuron processes information to produce behavior is not well understood.<\/p>\n\n\n\n
