Scientists were able to look at the brains of freely-moving octopuses for the first time using a new approach with an implanted device. The recordings revealed distinct patterns of brain activity, with some of them mirroring states that were observed in mammals before and others looking totally alien. Studying octopuses in motion poses challenges due to their eight highly flexible arms, which grant them access to their entire bodies.
The Brain Activity of Octopuses
The mobility of octopuses allows them to detach any kit placed on them. To overcome this challenge, researchers came up with a waterproof device they implanted inside octopuses, with electrodes going into the median superior frontal lobe and vertical lobe. These regions are rather interesting because they are thought to be responsible for memory and visual learning, which is what the researchers were hoping to investigate.
The research was led by Dr. Tamar Gutnick, who, together with her colleagues at the Physics and Biology Unit at the Okinawa Institute of Science and Technology, wanted to learn how the brain works. According to Gutnick, octopuses are the perfect animal to compare to mammals because they have a large brain, a unique body, and advanced cognitive abilities, developed differently from those of vertebrates.
Octopuses Are Very Intelligent
Octopuses have a high level of intelligence but are distant in evolutionary terms from other smart animals. Because they have evolved underwater, even some astrobiology researchers took an interest in them to explore how life could go about in a water world.
Gutnick and her colleagues did some procedures on anesthetized octopuses to get the implants in them, which then recorded 12 hours of data. The octopuses then recovered in five minutes and slept, ate, and moved around while having their brain waves recorded. The results showed patterns of brain activity that appeared similar to those of mammals and some that had never been observed or described before. Those were made up of long-lasting, slow oscillations.
Kelly Ellis has worked with Queen legend Sir Biran May countless times throughout her career as a musical theater actress. So, it comes as no wonder that the “Bohemian Rhapsody” hitmaker hopped on board as soon as he got invited to play on Ellis’ lead single from her new album titled Kings and Queens. The song is called “Battlefield,” and it’s exciting, to say the least!
Kelly Ellis Was Inspired by Brian May
Kelly, now 44, said that she was inspired to create something that she’d actually really love listening to and performing live. That’s probably why the album feels much more laid-back and relaxed than some of her earlier works. Of course, having the chance to collaborate with one of the greatest guitar players alive certainly is inspiring in its own way.
The collaboration with Sir Brian May kind of happened on its own, too. Kelly went to his studio to play the album and threw her ideas at him. While that might not have been just what she expected in return, the Queen legend embraced all her suggestions and said he’d love to be part of making the album.
A Brief Overview of Kelly Ellis’ Career
Beginning her rise to fame back in 2002, Kelly starred in Queen’s musical We Will Rock You before nailing down various other prominent musical roles that helped her become one of the most prominent stars of the West End.
She’s admitted that she likes a good challenge. That’s precisely the reason why she’s decided to take on yet another exciting role, this time that of Titania in a production of one of Shakespeare’s most celebrated plays.
Kings and Queens is now out, and fans can listen to the lead single “Battlefield” online. It’s the one featuring Queen legend Sir Brian May.
