“Forgetting” Might Not Be a Bad Form of Learning, Mouse Study Suggests
Last year the neuroscientists suggested that changes in our ability to access specific memories are based on environmental feedback and predictability. And that rather than being a bug, forgetting may be a functional feature of the brain

Neurological Spreading Patterns of Disease-Causing Protein TDP-43 Identified
Our movements are controlled by multiple neural pathways that connect the brain and spinal cord. However, this flow of neural information is compromised in amyotrophic lateral sclerosis.

Largest Study of Brain Genetics Identifies How the Brain Is Organized
The largest ever study of the genetics of the brain – encompassing some 36,000 brain scans – has identified more than 4,000 genetic variants linked to brain structure.

Gene “Fingerprint” for Brain Aging Identified in Mice
Most of us who’ve reached middle age have noticed a slowing in memory and cognition, but scientists don’t have a clear picture of the molecular changes that take place in the brain to cause it, until now.

What Sparks Curiosity in Orangutans?
New research has succeeded in measuring the behavior of wild orangutans in their first encounter with an unfamiliar object, revealing the factors that influence curiosity.

Symbiotic Fungi Provide Chemical Cues for Bark Beetles
Bark beetle use the volatile fungal metabolites of their symbiotic fungi as important chemical signals in their attack on trees.

Astrocytes May Be the Key to Staying Awake Without Getting Tired
New animal research suggests that little-studied brain cells known as astrocytes are major players in controlling sleep need and may someday help humans go without sleep for longer without negative consequences.

Brain Scans Show Anxious People Use Less Suitable Part of the Brain
When choosing their behaviour in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious according to brain scans.

Protein Injection Replicates Exercise Benefits in Mouse Brain
Platelets secrete a protein during exercise that enhances neurogenesis in the hippocampus. A preclinical trial finds that systemic injection of the protein replicates the brain benefits induced by exercise.

Breakthrough in Brain Rejuvenation Identifies Anti-Aging Plasma Factor
Researchers have long known that the anti-aging hormone klotho, infusions of blood from younger animals and exercise can boost the brain function of aging mice. The underlying mechanism behind these changes has remained elusive until now.
