Final answer:
The two types of neural tube migration paths are radial and tangential migration, involving the outward and parallel movements of neurons, respectively. The methods of migration are somal translocation, where neurons move their cell bodies, and glial-mediated migration, where they travel along radial glial cells.
Step-by-step explanation:
The two types of neural tube migration paths are radial migration and tangential migration. Radial migration refers to the movement of neurons from the inner layers of the neural tube outward towards the outer layers. Tangential migration is the movement of neurons in a direction parallel to the neural tube's surface. The two methods of migration by which they move are somal translocation and glial-mediated migration. Somal translocation involves the neuron moving its cell body, often extending a leading process and subsequently pulling the soma into the new location. Glial-mediated migration, on the other hand, involves newly generated neurons migrating along the radial glial network, which acts as a scaffolding for their journey.
