The study is published in the journal PLOS One. The neurobiological gene receptors we’ve identified could help other scientists develop drugs to target neophobia or anxiety even in our own species,” Lattin explains. “The fear of new things, or neophobia, is a problem some people struggle with. Birds too scared to approach the new object showed more gene expression for the estrogen receptor beta gene, which studies link to the development of anxiety. Researchers say dopamine receptor 2 displays a link to both boldness and exploration. For instance, there was more dopamine receptor 2 transcripts in the fearless birds. They found some active genes in the hippocampus of fearless birds differed from those in the hippocampus of fearful birds. After several weeks of testing the sparrow’s fear behavior, the scientists studied their brain activity.

The other three were too afraid to approach the new object. The team studied six female house sparrows, with three showing more signs of fearlessness in trying a change (a red wrist coil keychain, white plastic cover, a green plastic Easter egg, or a painted food dish) in their feeding dish. Birds of a feather - still express different genes For example, when wildlife are presented with something new in their environment, the genes in their brains respond, helping them process the information, compare it to past experience and decide whether they should approach or avoid the novel object,” Lattin says. Now I watch hundreds of aspiring female entrepreneurs inch forward very slowly, waiting to reveal what were working on until its totally ready until its. So when the guards came to get Paul, he was gone, but the jail door was locked. He was in jail and the door just opens, an angel of the Lord opened the jail gate and told him to go and preach in the center of town the next day. Here is where the super powers comes in Paul. So they locked him in jail to face trial. “One of the interesting things about the hippocampus is it can play an important role in decision-making. These acts made the Sadducees very anger. Of the brain areas, the hippocampus - a brain area involved in learning, navigation, and memory - showed the most difference in brain activity. In the flock, the researchers observed the expression of certain genes in three out of four brain regions of fearless birds that were not active in birds displaying signs of fear. ![]() Having a flock that ranges from fearlessness and fearfulness could explain how these birds adapted to changes in human-altered environments. Several animal species such as house sparrows have a mix of personalities related to fear. ![]() “Our study provides interesting and important evidence that some of the behavior differences could be led by gene expression,” says Christine Lattin, lead author of the study and assistant professor in the Department of Biological Sciences at LSU, in a university release. Now, a new study shows that fearlessness and fearfulness all comes down to how your brain is wired. What makes some animals more afraid of new things than others? It’s a question that has stumped biologists for years considering that there are many benefits to being fearless - including exploring new areas to live, trying out new food or places for food, and better adapting to changes in the environment.
