The Impact of Golgi Apparatus on Brain Development and Neuronal Circuitry

Researchers have discovered that the Golgi apparatus, an organelle within neurons, plays a crucial role in dendritic refinement during early postnatal brain development. The Golgi apparatus interacts with the neurotransmitter receptor NMDAR to shape neural circuit organization. This process is essential for proper brain development and functionality. Disruption to either the NMDAR signal or the Golgi polarity can lead to inappropriate changes in dendrite shape and direction. The study highlights the overlooked role of subcellular structures in neuronal circuit reorganization.
