A neuroscience feature explaining a mouse brain mapping study that reveals distinct norepinephrine circuits and what readers might learn from its approach.
Key Takeaways
- Brain’s “Blue Place” Rewrites How Norepinephrine Drives Learning - Neuroscience News Topography of locus coeruleus norepinephrine neurons in the mouse brain.
- The study also reconstructed individual locus coeruleus neurons, uncovering one with an axon measuring over 70 centimeters, the longest single neuron ever documented in a mouse.
- Record-Breaking Axon Length: The team found locus coeruleus axons average approximately 35 centimeters in length, with one reconstructed neuron measuring 70.32 cm,the longest brain cell ever recorded in a mouse.
