What Octopus and Human Brains Have in Common – Neuroscience News

Summary: Octopuses have a massively expanded repertoire of miRNA in their neural tissue, reflecting a similar development to that which occurs in vertebrates. Findings suggest miRNA plays a significant role in the development of complex brains. Source: MDC Cephalopods like octopuses, squids and cuttlefish are highly intelligent animals with complex nervous systems. In “Science Advances”, …

Octopus Brains Evolved to Share a Surprising Trait with Our Brains

EMBARGO Friday 25 November 1900 GMT | Saturday 26 November 0600 AEDT Our glorious little blue marble of a planet is filled with an astonishingly diverse array of lifeforms, but some are definitely more peculiar than others. This is particularly true of the octopus, an animal so strange that it regularly invites comparisons to aliens. …

Major Discovery About Mammalian Brains Surprises Researchers – Neuroscience News

Summary: V-ATPase, a vital enzyme that enables neurotransmission is able to switch on and off randomly, even taking hours-long breaks. Source: University of Copenhagen In a new breakthrough to understand more about the mammalian brain, University of Copenhagen researchers have made an incredible discovery. Namely, a vital enzyme that enables brain signals is switching on …

How Squid and Octopus Get Their Big Brains – Neuroscience News

Summary: Neural stem cells of cephalopods act in a similar way to those of vertebrates during nervous system development. Source: Harvard Cephalopods — which include octopus, squid, and their cuttlefish cousins ​​— are capable of some truly charismatic behaviors. They can quickly process information to transform shape, color, and even texture, blending in with their …

Shocking Experiment Indicates Our Brains Use Quantum Computation

The results of an experiment to explore the human brain and its workings, which was adapted from an idea developed to prove the existence of quantum gravity, indicate that our brains use quantum computation. Scientists believe our brains could use quantum computation after taking a concept developed to prove the existence of quantum gravity and …

New research suggests our brains use quantum computation

Credit: CC0 Public Domain Scientists from Trinity College Dublin believe our brains could use quantum computation. Their discovery comes after they adapted an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The brain functions measured were also correlated to short-term memory performance and conscious awareness, suggesting …

A Huge New Data Set Pushes the Limits of Neuroscience

A Huge New Data Set Pushes the Limits of Neuroscience

So neuroscientists use an approach called “dimensionality reduction” to make such visualization possible—they take data from thousands of neurons and, by applying clever techniques from linear algebra, describe their activities using just a few variables. This is just what psychologists did in the 1990s to define their five major domains of human personality: openness, agreeableness, …

Key Differences Revealed Between Brains of Modern Humans and Neanderthals

By Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) September 9, 2022 New research reveals that a change in a single amino acid in the protein TKTL1 results in greater neuron production in the developing frontal lobe of the neocortex in modern humans compared to Neanderthals. Scientists uncover a greater neuron production in …

The study reveals striking differences in the brains of modern humans and Neanderthals

Neanderthals have long been portrayed as our dim-witted, thuggish cousins. Now groundbreaking research has – while not confirming the stereotype – revealed striking differences in the brain development of modern humans and Neanderthals. The study involved inserting a Neanderthal brain gene into mice, ferrets and “mini brain” structures called organoids, grown in the lab from …
