In a recent study published in the journal eLife, scientists detailed an experiment involving glass-knife fish in a fish tank,media CNET reported. Using high-resolution cameras, they recorded a large amount of micro-sensory data about three weak-powered glass swordfish and their famous ribbon fins, which moved back and forth between hidden “tunnel houses.” After recording nearly 40,000 movements per fish, the researchers created computer models of each fish’s brain and body.
But they didn’t stop there. The researchers then took data on each fish’s information processing and motion system and created a virtual version of the fish, swapping the virtual fish’s brain into another virtual fish’s body. They tested the “brain-changing” virtual fish to see how they reacted when they did not have sensory data without any virtual object, and then combined with the virtual object’s sensory data.
The researchers aim to find out how fish behaves when you change the connection between sensory input and neural circuits. The question is whether the key to fine motion control, such as the control used to hit a baseball or send text messages, lies in the relationship between the nervous system and the brain, or whether our sensory input makes a difference. The key for researchers has proved to be to get sensory feedback on virtual fish.
When they give sensory feedback to the new virtual fish exchanged by the brain, the virtual fish move on as if it had never exchanged the brain. However, without sensory feedback, the brain-swapped virtual fish cannot adapt to having the wrong virtual brain in the wrong virtual body.
“This study shows that sensory feedback plays a profound role in everything we do,” Eric Fortune, lead author of the study, said in a press release Monday. People have been trying to figure out how animal movements always work. It turns out that exchanging the brains of these fish is a good way to solve this basic problem and better understand how we control our bodies. “
The researchers say the scientific strange fish experiment could help robotic engineers gather useful insights into sensor technology, and the fish’s ribbon fins could improve our understanding of complex muscle activation, which can outperform humans in terms of human motion control.
