Synapse formation in cultured hippocampal neurons after 7 days in vitro. Cells were immunostained for MAP2, a microtubule associated protein localized to dendrites but not axons (green), and synapsin...

Dendritic development in cultured hippocampal neurons after 17 days in vitro. Neurons were immunostained for MAP2, a microtubule associated protein localized to dendrites but not axons to show the ex...
