Does consuming fruit during pregnancy improve cognition in babies?
on March 4, 2020 at 7:17 pm
A new study explores in greater depth the effect on infant cognition of drinking fruit juice while pregnant.
Bees recognize that six is more than four
on March 2, 2020 at 3:37 pm
A new study at the University of Cologne proves that insects can perform basic numerical cognition tasks. Their neuronal network can also be used to perform successful machine learning.
Researchers Were Not Right About Left Brains, Study Suggests
on February 14, 2020 at 7:43 pm
Brain imprints on cranial bones from great apes and humans refute the long-held notion that the human pattern of brain asymmetry is unique, according to new research.
Elephants' unique interactions with their dead
on February 6, 2020 at 11:43 pm
Stories of unique and sentient interactions between elephants and their dead are a familiar part of the species' lore, but a comprehensive study of these interactions has been lacking -- until now. A recent review of documented field observations of elephants at carcasses reveals patterns of elephants' behavior toward their dead, regardless of the strength of former relationships with the deceased individual.
Early life experiences biologically and functionally mature the brain
on February 3, 2020 at 4:43 pm
Experiences early in life have an impact on the brain's biological and functional development, shows a new study by a team of neuroscientists.
Strongly 'handed' squirrels less good at learning
on January 20, 2020 at 4:34 pm
Squirrels that strongly favor their left or right side are less good at learning, new research suggests.
New dog, old tricks? Stray dogs can understand human cues
on January 17, 2020 at 1:08 pm
Pet dogs are highly receptive to commands from their owners. But is this due to their training or do dogs have an innate ability to understand human signals? A new study finds that 80% of untrained stray dogs successfully followed pointing directions from people to a specific location. The results suggest that dogs can understand and respond to complex gestures without any training, meaning that dogs may have an innate connection to human behaviors.
How zebra finches learn to sing
on January 15, 2020 at 5:06 pm
Complex learning processes like speaking or singing follow similar patterns. Using the example of zebra finches, researchers have investigated how young birds imitate the courtship songs of their fathers and practice them thousands of times. The study has revealed what aspects of the song are remembered overnight, and that sleep allows the bird to optimally build upon the progress made on the previous day.
African grey parrots spontaneously 'lend a wing'
on January 9, 2020 at 6:01 pm
People and other great apes are known for their willingness to help others in need, even strangers. Now, researchers have shown for the first time that some birds -- and specifically African grey parrots -- are similarly helpful.
Dogs process numerical quantities in similar brain region as humans
on December 18, 2019 at 8:33 pm
The results of a new canine numerosity study suggests that a common neural mechanism has been deeply conserved across mammalian evolution.
Crows consciously control their calls
on August 27, 2019 at 6:57 pm
Crows can voluntarily control the release and onset of their calls, suggesting that songbird vocalizations are under cognitive control.
Understanding the animal brain could help robots wash your dishes
on August 21, 2019 at 9:37 pm
Neuroscientists show how evolution and animal brains can be a rich source of inspiration for machine learning, especially to help AI tackle some enormously difficult problems, like doing the dishes.
Studying animal cognition in the wild
on August 20, 2019 at 2:15 pm
Studying cognition in the wild is a challenge. Field researchers and their study animals face many factors that can easily interfere with their variables of interest and that many say are 'impossible' to control for. A novel observational approach for field research can now guide young scholars, who want to study cognition in the field before this opportunity disappears.
Three concepts from complexity could play a big role in social animal research
on August 1, 2019 at 7:27 pm
A new article lays out three concepts from complex systems science that could advance studies into animal social complexity.
An AI technology to reveal the characteristics of animal behavior only from the trajectory
on July 16, 2019 at 1:55 pm
Recording the movements of people and animals has become easy because of small GPS devices and video cameras. However, the reasons for such movements remain difficult to infer. Scientists have developed a flexible artificial intelligence technology to understand the movement of animals, ranging from roundworms in petri dishes to penguins in the Antarctic Ocean. This method may make it easier to understand animal movements as well as their underlying brain activities.
Environment, not evolution, might underlie some human-ape differences
on July 15, 2019 at 1:48 pm
Apes' abilities have been unfairly measured, throwing into doubt the assumed belief that human infants are superior to adult chimpanzees, according to a new study by leaders in the field of ape cognition.
How octopus arms make decisions
on June 25, 2019 at 2:24 pm
Researchers studying the behavior and neuroscience of octopuses have long suspected that the animals' arms may have minds of their own. A new model is the first attempt at a comprehensive representation of information flow between the octopus's suckers, arms and brain, based on previous research in octopus neuroscience and behavior, and new video observations conducted in the lab.
Bees can link symbols to numbers, study finds
on June 5, 2019 at 9:14 pm
We know bees get the concept of zero and can do basic math. Now researchers have discovered they may also be capable of connecting symbols to numbers. It's a finding that sheds new light on how numerical abilities may have evolved over millennia and even opens new possibilities for communication between humans and other species.
What makes memories stronger?
on April 29, 2019 at 3:18 pm
Scientists have found that highly demanding and rewarding experiences result in stronger memories. By studying navigation in rats, the researchers traced back the mechanism behind this selective memory enhancement to so-called replay processes in the hippocampus, the memory-processing center of the brain.
Researchers discover the source of new neurons in brain's hippocampus
on March 28, 2019 at 7:08 pm
Researchers have shown, in mice, that one type of stem cell that makes adult neurons is the source of this lifetime stock of new cells in the hippocampus. These findings may help neuroscientists figure out how to maintain youthful conditions for learning and memory, and repair and regenerate parts of the brain after injury and aging.
