Making Sense of Sensory Connections

A key feature of human and animal brains is that they are adaptive; they are able to change their structure and function based on input from the environment and on the potential associations, or consequences, of that input. To learn more about such neural adaptability, researchers at Caltech have explored the brains of insects and identified a mechanism by which the connections in their brain change to form new and specific memories of smells.

Worm Seeks Worm: Caltech Researchers Find Chemical Cues Driving Aggregation in Nematodes

Scientists have long seen evidence of social behavior among many species of animals. Dolphins frolic together, lions live in packs, and hornets construct nests that can house a large number of the insects. And, right under our feet, it appears that roundworms are having their own little gatherings in the soil. Until recently, it was unknown how the worms communicate to one another when it's time to come together. Now, however, researchers from Caltech have identified, for the first time, the chemical signals that promote aggregation. More...
