Example Sentences

They discovered that a protein called MEIS2 plays an important role when a precursor cell 'decides' whether it should turn into an interneuron or into a projection neuron: MEIS2 assists the cellular machinery to activate the genes that are required for a precursor cell to become a projection neuron.

From Science Daily

"Our study further provides a link between the MAP6 dysfunction and the interneuron signal dysfunction, and we now know that there are two proteins that interact and that one could alter the other," Gu said.

From Science Daily

Motor neurons have often been thought of as passive cells controlled by upstream interneuron inputs, whereas interneurons had been thought to be the driving force behind the assembly and function of spinal motor circuits4.

From Nature

Wan et al. therefore asked whether this activity originates in the motor neurons themselves, or reflects interneuron control.

From Nature
