Neuron theory is an example of consilience where low level theories are absorbed into higher level theories that explain the base data as part of higher order structure. As a result the neuron doctrine has multiple elements, each of which were the subject of low level theories, debate, and primary data collection. Some of these elements are imposed by the necessity of cell theory that Waldeyer was trying to use to explain the direct observations, and other elements try to explain … WebMar 1, 2024 · contact sites at each end, allowing cytoplasmic continuity (Fig 1); however, few studies have successfully demonstrated this feature.
