Golgi Polarization (IMAGE) Research Organization of Information and Systems Caption The image shows a spiny stellate neuron (magenta) and its Golgi apparatus (white) in the mouse barrel cortex at postnatal day 5. The study found that the Golgi apparatus shows a biased distribution in one side of the neuron only during the postnatal critical period of circuit reorganization. This lateral Golgi polarity instructs the direction in which the neuron expands its dendrites for establishing precise neuronal circuit.
