Neuroscientists have typically thought of energy supply to the brain as demand-based. A supply-limited view offers another perspective toward aging and why multitasking can be difficult.
Parents provide the energy needed for their young to grow large brains. Climate change may negatively affect birds’ brain development as it impacts food supplies.
By learning what parts of the brain are crucial for imagination to work, neuroscientists can look back over hundreds of millions of years of evolution to figure out when it first emerged.
Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.
An 18-month treatment with lecanemab slows functional and cognitive loss by 27 per cent in people with mild Alzheimer’s disease. But this is only the first step towards a real cure.
Impaired insulin receptors in the blood vessels between the blood and the brain may contribute to the insulin resistance observed in Alzheimer’s disease.
Microglia, immune cells disguised as brain cells, are known as the janitors of the brain. Dialing up their usual duties just enough could provide an avenue to treat neurodegenerative disease.
From warfare to entertainment and VR, brain-computer interface development has extended beyond prosthetics for patients with disabilities. Missing is full ethical consideration of the consequences.

Neuroscientists know that pregnant mothers’ brains change in ways that appear to help with caring for a baby. Now researchers have identified changes in new fathers’ brains, too.
