Most neurons have many branching extensions called dendrites that receive input from thousands of other neurons. Dendrites aren't just passive information-carriers, however. According to a new study from MIT, they appear ...

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, ...

Neurons in the human brain receive electrical signals from thousands of other cells, and long neural extensions called dendrites play a critical role in incorporating all of that information so the cells can respond appropriately.

Human neurons are much larger than those of model organisms mice and rats, so it's been unclear whether it's size that makes a difference in our brain's computational power. Now, in a study appearing October 18 in the journal ...
