Competition between brain hemispheres during sleep

Human beings are bilaterally symmetrical. As such, our brains are made of two halves called hemispheres, that communicate with each other with specialized fiber tracts running across the midline. While each hemisphere tends to deal with the senses (vision, hearing, touch) and motor control of the opposite side of the body, we are generally not aware of this partitioning of function, thanks to constant inter-hemispheric communication. In humans, the two hemispheres are also specialized for certain functions: language areas, for example, are typically in the left hemisphere.

Memories could be lost if two key brain regions fail to sync together, study finds

Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study led by the universities of Bristol and Heidelberg has found.

Insights into the evolution of the sense of fairness

A sense of fairness has long been considered purely human – but animals also react with frustration when they are treated unequally by a person. For instance, a well-known video shows monkeys throwing the offered cucumber at their trainer when a conspecific receives sweet grapes as a reward for the same task. Meanwhile, researchers have observed similarly frustrated reactions to unfair rewards in wolves, rats and crows. However, researchers still debate the reasons for this behavior: Does the frustration really stem from a dislike of unequal treatment, or is there another explanation? In a study with long-tailed macaques (Macaca fascicularis), researchers at the German Primate Center – Leibniz Institute for Primate Research (DPZ) have now confirmed an alternative explanatory approach in a collaborative project involving the Departments of Cognitive Ethology and Neurobiology.

Measuring octopus cognition

With eight arms, large eyes, and shape-shifting skin, octopus’ bodies appear almost otherworldly. Their cognitive abilities fascinate us because they are comparable to those of vertebrates, yet our evolutionary lines diverged about 550 million years ago. The combination of their intelligence and uniqueness prompted neuroscientists to study the brains of octopods as early as 150 years ago. An international team including the University of Göttingen has now, for the first time, succeeded in measuring brain activity in octopuses moving freely through the water. While such studies are well established in mammals and birds, until now this has not been possible in octopuses. The study was published in the scientific journal Current Biology.

Fish schools work a bit like the brain

What do the brain and a school of fish have in common? They are both capable of efficient collective information processing, although each unit within them only has access to local information. In the brain, it is the stimuli from 86 billion neurons that form the basis for information processing; in the shoal, it is the decisions of each individual on how to move and interact with neighbors. However, little is known about how biological systems like the brain or a swarm of fish manage to optimally bring together a multitude of individual pieces of information from different locations. There is a hypothesis according to which the best performance of the brain lies at the border between order and chaos, in the state of so-called criticality. Researchers of the Cluster of Excellence "Science of Intelligence" from Humboldt-Universität (HU), the Technical University of Berlin (TU), and IGB have now been able to demonstrate this hypothesis on a large school of fish. The study was published in Nature Physics.

Hertie Foundation establishes new institute combining artificial intelligence and neuroscience

Frankfurt am Main, February 7, 2023 - This month marks the launch of an outstanding project integrating artificial intelligence (AI) and neuromedicine – the Hertie Institute for Artificial Intelligence in Brain Health (Hertie AI). Founded on February 1 at the Medical Faculty of the University of Tübingen, it will be the first institute in Germany to research the prevention and early diagnosis of diseases of the nervous system using artificial intelligence methods.
