Researchers conducted a first-of-its-kind study designed to investigate brain connectivity in 130 mammalian species. The intriguing results, contradicting widespread conjectures, revealed that brain connectivity levels are equal in all mammals, including humans.
Their study revealed a universal law: Conservation of Brain Connectivity which denotes that the efficiency of information transfer in the brain’s neural network is equal in all mammals, including humans. They also discovered a compensation mechanism which balances the connectivity in every mammalian brain. This mechanism ensures that high connectivity in a specific area of the brain, possibly manifested through some special talent (e.g. sports or music) is always countered by relatively low connectivity in another part of the brain.
In future projects they will investigate how the brain compensates for the enhanced connectivity associated with specific capabilities and learning processe.

The authors reviewed recent work in the intersection of cognitive science, computational neuroscience and artificial intelligence. Computational models that mimic brain information processing during perceptual, cognitive and control tasks are beginning to be developed and tested with brain and behavioral data.

A research team recently found new evidence revising the traditional view of the primate brain’s visual system organization. This remapping of the brain could serve as a future reference for understanding how the highly complex visual system works, and potentially influence the design of artificial neural networks for machine vision.

The brain is organized into a network of specialized networks of nerve cells.
For such a brain architecture to function, these specialized networks ―each located in a different brain area― need to be able to communicate with each other. But which conditions are required for communication to take place and which control mechanisms work?
Researchers at the Bernstein Center Freiburg and colleagues in Spain and Sweden are proposing a new model that combines three seemingly different explanatory models. Their conclusions have now been published in Nature Reviews Neuroscience.

Researchers have shown that astrocytes ― long-overlooked supportive cells in the brain ― help to enable the brain’s plasticity, a new role for astrocytes that was not previously known.
The findings could point to ways to restore connections that have been lost due to aging or trauma.
