In 1898, Camillo Golgi, an eminent Italian physician and pathologist, published a landmark paper on the structure of “nervous cells.” In addition to the organelle that still bears his name, the Golgi apparatus, he described “a delicate covering” surrounding neurons’ cell bodies and extending along their dendrites. That same year, another Italian researcher, Arturo Donaggio,...

Study finds the frequency of alpha brain waves could be used to assess a person’s predisposition to pain
The personal experience of pain is highly variable among individuals, even in instances where the underlying injury is assessed to be identical. Credit: University of Birmingham The frequency of alpha brain waves can be used as a measure of an individual’s vulnerability to developing and experiencing pain, researchers at the University of Birmingham in the...

Study overturns age-old theory of brain learning
For decades, scientists thought that learning occurs in synapses, or the numerous junctions between brain cells. But now, a new study proposes that learning occurs in a few dendrites, the branches that feed inputs to the brain cell, or neuron. The results of a new study offer a brand new insight into brain learning. In...

Neural fingerprints of altruism
There are two war veterans, both with penetrating traumatic brain injury (TBI) caused by a gunshot. One of them tends to donate his own money to societal entities he believes in, and the other one punishes institutions that don’t represent him. The answer for these behavioral differences rely on brain areas, which, after being damaged...

Cell therapy could improve brain function for Alzheimer’s disease
PET scan of a human brain with Alzheimer’s disease. Like a great orchestra, your brain relies on the perfect coordination of many elements to function properly. And if one of those elements is out of sync, it affects the entire ensemble. In Alzheimer’s disease, for instance, damage to specific neurons can alter brainwave rhythms and...
