by Margaret Osborne, Cold Spring Harbor Laboratory Hypothetical read-out mechanisms of the counting neuron. A) This model translates the continuous firing rate of the 1-2-3-many counter neuron into a discrete representation. Because this model uses repetition suppression, larger firing rates correspond to less familiar odors. The counter synapses onto four downstream neurons, each with succcessively...
by UK Research and Innovation Healthy human brain temperature extremes showing relatively hot temperatures in post-ovulation females in the morning compared with coldest temperatures in males at night. Lighter yellow represents hotter temperatures. Credit: N Rzechorzek/MRC LMB/Brain New research has shown that normal human brain temperature varies much more than we thought, and this could...
by Case Western Reserve University Prions. Credit: Case Western Reserve University Case Western Reserve University researchers studying prions—misfolded proteins that cause lethal incurable diseases—have identified for the first time surface features of human prions responsible for their replication in the brain. The ultimate goal of the research is to help design a strategy to stop prion disease in humans—and, ultimately, to translate...
KYOTO UNIVERSITY Stem cell research has allowed medicine to go places that were once science fiction. Using stem cells, scientists have manufactured heart cells, brain cells and other cell types that they are now transplanting into patients as a form of cell therapy. Eventually, the field anticipates the same will be possible with organs. A new paper...
