The Neuron Expedition was led by the hydrogeologist Helena Vysoká, who first wanted to take water samples from a depth of 384 metres and, with a team of cave divers, explore the last blank space on the map of Czechia. Along the way the team also found that the Hranice Abyss is 404 metres deep, making it the deepest flooded cave in the world.
