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.
Unexpected discovery reveals a new mechanism for how the cerebellum extracts signal from noise
Research at the University of Calgary’s Hotchkiss Brain Institute (HBI) has demonstrated the novel expression of an ion channel in Purkinje cells specialized neurons in the cerebellum, the area of the brain responsible for movement. Ray W. Turner, PhD, Professor in the Department of Cell Biology & Anatomy and PhD student Jordan Engbers and colleagues published this finding in the January edition of the journal Proceedings of the National Academy of Sciences (PNAS).
