Clytia hemisphaerica, viewed from above. The round, transparent animal is about one centimeter across when fully mature, with a central mouth, and tentacles arranged uniformly around its outer edges like numbers on a clock. This jellyfish also has four oval-shaped gonads visible on its body.
Clytia hemisphaerica, viewed from above. The round, transparent animal is about one centimeter across when fully mature, with a central mouth, and tentacles arranged uniformly around its outer edges like numbers on a clock. This jellyfish also has four oval-shaped gonads visible on its body. The human brain has 100 billion neurons, making 100 trillion connections. Understanding the precise circuits of brain cells that orchestrate all of our day-to-day behaviors-such as moving our limbs, responding to fear and other emotions, and so on-is an incredibly complex puzzle for neuroscientists. But now, fundamental questions about the neuroscience of behavior may be answered through a new and much simpler model organism: tiny jellyfish. Caltech researchers have now developed a kind of genetic toolbox tailored for tinkering with Clytia hemisphaerica , a type of jellyfish about 1 centimeter in diameter when fully grown.
