Deep inside the brain: Unraveling the dense networks in the cerebral cortex

October 24, 2019 0 Comments Animal Learning and Intelligence, Biology, Brain Tumor, Brain-Computer Interfaces, Intelligence, mice, Nervous System, neuroscience, Psychology Research

Mammalian brains, with their unmatched number of nerve cells and density of communication, are the most complex networks known. While methods to analyze neuronal networks sparsely have been available for decades, the dense mapping of neuronal circuits is a major scientific challenge. Researchers have now succeeded in the dense connectomic mapping of brain tissue from the cerebral cortex, and quantify the possible imprint of learning in the circuit.

Monkeys and other animals communicate through calls that can differ depending on region. The common marmoset is one such animal that communicates using regional dialects. Researchers have now found out that they even adapt their dialect when they move to a different area.

Researchers studied fossilized Moroccan Ampyx trilobites, which lived 480 million years ago and showed that the trilobites had probably been buried in their positions — all oriented in the same direction. Scientists deduced that these Ampyx processions may illustrate a kind of collective behavior adopted in response to cyclic environmental disturbances.

Respiratory diseases linked with high blood pressure in lungs

October 17, 2019 0 Comments Animal Learning and Intelligence, animals, COPD, Dogs, Heart Disease, Hypertension, Lung Disease, Veterinary Medicine

Pulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail.

Researchers solve puzzle about link between genetic mutations, mating in fruit flies

October 16, 2019 0 Comments Animal Learning and Intelligence, animals, Behavioral Science, Biology, Evolutionary Biology, Genetics, Insects (including Butterflies), Mating and Breeding

More than a century ago, early geneticists showed that the inheritance of a single mutation by fruit flies can change the insect's body color and simultaneously disrupt its mating behavior.

The brain does not follow the head

The human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production. A study by anthropologists now shows that changes in the brain occurred independent of evolutionary rearrangements of the braincase.
