MIT researchers have mapped the neural processes that allow C. elegans to navigate toward attractive odors or away from aversive ones. By tracking the electrical activity of over 100 neurons, the study revealed a specific sequence of neural activation, moving through stages of sensing, planning turns, reversing, and executing movement, that shows these organisms act with more intentionality than previously understood. The coordination of this entire sensorimotor arc is driven by the neuromodulator tyramine.
- specific neurons responsible for odor detection, turn planning, and motor execution.
- precise sequence of forward, reverse, and turning motions to navigate gradients.
- Role of the neuron RIM and the chemical tyramine in organizing sequential brain activity patterns.
