A team of researchers at Stanford University has found synapse-boosting factors in the blood of young mice. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the ...
Neurons pass on information to one another via synapses. The vast majority of these synapses are excitatory, which increase the activity of the receiving neuron. Around 10 to 20 percent of synapses have the opposite effect, ...

CT1 is different. In general, a nerve cell receives input from a number of presynaptic cells, processes the signals, and passes its output to downstream cells. In the cell CT1, however, each of the approximately 1400 cell ...
