525-Million-Year-Old Fossil Defies Textbook Explanation for Brain Evolution

Posted by in categories: evolution, neuroscience

Summary: The fossil of a 525-million-year-old tiny sea creature with a preserved nervous system may solve a century-long debate about how the brains of arthropods evolved.

Fossils of a tiny sea creature that died more than half a billion years ago may compel a science textbook rewrite of how brains evolved.

Quantum Physics Axed Materialism. Many Hope the World Won’t Know

Posted by in categories: neuroscience, quantum physics

Quantum mechanics, which developed in the early 20th century, has been a serious blow to materialism.

There is no way to make sense of it if immaterial entities like information, observation, or the mind are not real. Theoretical physicist Sabine Hossenfelder struggles against the effects of this fact.

Four-Month-Old Ravens Can Be As Smart As Adult Apes, Cognitive Tests Shows

Posted by in category: neuroscience

You really can’t call a raven a birdbrain, because they and other corvids (the avian family they belong to) are actually pretty smart. New research published in Scientific Reports suggests that, at just four months old, these birds can compete as well as adults chimpanzees and orangutans in certain cognitive tasks.

The work focused on eight hand-raised ravens. They were tested at the age of four, eight, 12, and 16 months using the Primate Cognition Test Battery (PCTB), a standardized test for assessing animal cognition. The researchers tested if the birds exhibited spatial memory, understood numbers and addition, and if they could learn from and communicate with their handlers. They even looked at object permanence, which is the ability to know that an object still exists even if it’s out of sight.

Groundbreaking New Technology Allows People To Listen to Music Through Touch

Posted by in categories: information science, media & arts, neuroscience

A ground-breaking prototype developed by experts from the Department of Electronics at the University of Malaga and members of the R&D group “Electronics for Instrumentation and Systems,” will allow those with hearing loss to listen to music through the sense of touch.

It consists of an audio-tactile algorithm that transforms monophonic music into tangible stimuli based on vibration utilizing “tactile illusions.” According to the researchers, “It’s like ‘hacking’ the nervous system to receive a different response to the real stimulus sent.”

Scientists develop RNA-targeting strategy to repair genetic cause of ALS and dementia

Posted by in categories: biotech/medical, genetics, health, neuroscience

Scientists at University of Florida (UF) Scripps Biomedical Research have developed a potential medicine for a leading cause of ALS and dementia that works by eliminating disease-causing segments of RNA. The compound restored the health of neurons in the lab and rescued mice with the disease.

The potential medication is described this week in the scientific journal Proceedings of the National Academy of Sciences. It is designed to be taken as a pill or an injection, said the lead inventor, professor Matthew Disney, Ph.D., chair of the UF Scripps chemistry department. Importantly, experiments showed that the compound is small enough to cross the blood-brain barrier, a hurdle other approaches have failed to clear, he said.

Amyotrophic lateral sclerosis, or ALS, progressively destroys neurons that control muscles, leading to worsening muscle loss and eventually death. The mutation, a leading cause of inherited ALS, is referred to as “C9 open reading frame 72,” or C9orf72. This mutation also leads to one form of frontotemporal dementia, a brain disease that causes the brain’s frontal and to shrink, resulting in changes in personality, behavior and speech, ultimately resulting in death.

Psychedelics: Chemicals, Consciousness, and Creativity

Posted by in categories: chemistry, neuroscience

Could psychedelics make you more creative? Shift your mind, connect you to others, and help you access a younger, more malleable version of yourself? Activist Rick Doblin, neuroscientist Gül Dölen, and musician Reggie Watts join Brian Greene for a mind-bending and multidisciplinary conversation about the promises and pitfalls of these “magic” molecules and their impact on creativity, connection, and consciousness.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Breakthrough study reveals that human and octopus brains have common features

Posted by in categories: evolution, neuroscience

The study’s findings could play a crucial role in developing a complex brain.

A common feature that connects humans and octopuses has only recently been revealed. It may sound a little bit quirky to you, but not to scientists.

Published very recently in Science Advances today, a team led by Nikolaus Rajewsky of the Max Delbrück Center has now shown that their evolution is linked to a dramatic expansion of their microRNA repertoire.
