Abstract
Simultaneous recordings of calcium action potentials directly from growth cones and from somata of neuroblastoma cells indicated that they could be generated in the neurites at or near growth cones. Growth cone responses were measured with a fluorescent voltage-sensitive dye and a 5-milliwatt helium-neon laser microbeam as a monitoring light source.Keywords
