Hillock in neurons
WebIn neurons, information relevant to ion channel trafficking and compartmentalization into sub-domains of the plasma membrane is far from being elucidated. Besides, whereas information on dendritic targeting is beginning to emerge, less is known about the mechanisms leading to the polarized distribution of proteins in axon. WebOct 5, 2024 · Axon hillock currents enable single-neuron-resolved 3D reconstruction using diamond nitrogen-vacancy magnetometry - Communications Physics. Magnetometry of neural axons has been demonstrated in worms, but it’s application to mammals is more challenging due to the lower signal and connection densities.
