Cholinergic Amacrine: Heritable Nerve Cell Creates A 'Personal' Space

Neurons are vital to the functional organization of the central nervous system. Multiple cell types are present within any brain structure, but the rules governing their positioning, and the molecular mechanisms mediating those rules, are unknown. A new study finds that a particular neuron, the cholinergic amacrine cell, creates a "personal space" in much the same way that people distance themselves from one another in an elevator. The study also says that this feature is heritable and identifies a genetic contributor to it, pituitary tumor-transforming gene 1 (Pttg1). read more
