In Dreams of Color: Octopuses Show REM-Like Sleep Patterns – Neuroscience News

It shows an octopus.

Summary: Octopuses, despite their completely different brain structures, show sleep cycles similar to humans. Research shows octopuses enter an active sleep stage similar to REM sleep in humans, suggesting the presence of this sleep stage in complex cognition in the species. The scientists also discovered that sleep disruption prompts octopuses to re-enter this active phase … Read more

Cognitive Flexibility: Neural Connections Key to Adapting to Change Unearthed – Neuroscience News

It shows neurons.

Summary: A recent discovery has identified a specific type of neuronal connection in the prefrontal cortex that is responsible for updating our understanding of the world and its rules. The connection, formed by inhibitory neurons, communicates with neurons located far away in the opposite hemisphere of the prefrontal cortex. The role of this connection was … Read more

First programmable RNA-guided system found in eukaryotes

A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT discovered the first programmable RNA-guided system in eukaryotes -; organisms that include fungi, plants, and animals. In a study in Nature, the team describes how the system is based on … Read more

Orangutans Make Two Sounds Simultaneously: A Clue to the Evolution of Human Speech – Neuroscience News

It shows an orangutan.

Summary: Orangutans are capable of simultaneously producing two different sounds, similar to human beatboxers or songbirds. Through observations of vocalizing populations of orangutans in Borneo and Sumatra, researchers discovered this shared vocal phenomenon. The findings raise interesting questions about the evolution of human speech and beatboxing abilities. Researchers argue that the ability to produce dual … Read more
