Intermediary neuron acts as synaptic cloaking device, says Carnegie Mellon study

Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link brain anatomy to brain function. But a new study from has found that a specific type of neuron might be thwarting their efforts at mapping the connectome by temporarily cloaking the synapses that link a wide field of neurons.
