Researchers at University of California, Berkeley have released a study about how bats navigate in social groups, and they think it may provide answers to some human behavior and even insight into Alzheimer's disease.
BERKELEY - The phrase"blind as a bat" may be an alliterative simile, but that doesn't make it true. Bats can in fact see, but they use still more of their senses to navigate. Now researchers at University of California, Berkeley have released a study about how bats navigate in social groups, and they think it may provide answers to some human behavior and even insight into Alzheimer's disease.
Researchers at UC Berkeley used wireless neural devices to monitor the hippocampal brain activity in Egyptian fruit bats as they flew freely in a large flight room and moved among"tightly clustered" social groups of other bats. The scientists found something that surprised them, they said. The neurons in the bat brains that stored"place" also stored far more than just the bat's location.
Michael Yartsev, associate professor of bioengineering at UC Berkeley, said that what is groundbreaking about this is that it is the one of the first papers to show identity representation in a non-primate brain. In short, they found a neural basis in collective behavior -- shining a light on what makes social animals, including people, tick."The bats also showed strong preferences for flying toward specific 'friend' bats," said postdoctoral fellow Angelo Forli.

Researchers identify the link between memory and appetite in the human brain to explain obesityDisrupted connections between memory and appetite regulating brain circuits are directly proportional to body mass index (BMI), notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder (BED), according to new research. The research notes that individuals who are obese have impaired connections between the dorsolateral hippocampus (dlHPC) and the lateral hypothalamus (LH), which may impact their ability to control or regulate emotional responses when anticipating rewarding meals or treats.

Researchers construct first global map of insect mitochondrial genetic diversityUnderstanding global patterns of species genetic diversity is an integral part of monitoring and preserving life on Earth. To date, however, scientists have mapped macrogenetic patterns in vertebrates exclusively. Macrogenetics uses publicly-available data to identify global drivers of genetic diversity. Only 5% of all known living animal species are vertebrates while 95% are invertebrates. More than half of invertebrates are insects.
