Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient’s brain will suffer from the spread, neuron to neuron, of “prion-like” toxic proteins — a process they say underlies all forms of dementia.

Seeing movement: Why the world in our head stays still when we move our eyes
Scientists from Germany discovered new functions of brain regions that are responsible for seeing movement.
Researchers discover drug target for stimulating recovery from stroke
Investigators at the Stanford University School of Medicine have shown that removing a matched set of molecules that typically help to regulate the brain’s capacity for forming and eliminating connections between nerve cells could substantially aid recovery from stroke even days after the event. In experiments with mice, the scientists demonstrated that when these molecules are not present, the mice’s ability to recover from induced strokes improved significantly.
Study shines light on brain mechanism that controls reward enjoyment
What characterizes many people with depression, schizophrenia and some other mental illnesses is anhedonia: an inability to gain pleasure from normally pleasurable experiences.
Alzheimer’s disease spreads through linked nerve cells, brain imaging studies suggest
Alzheimer’s disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.
