Are You Guilty Of These 3 Cognitive Biases In Decision Making?

Posted by in categories: evolution, information science, neuroscience

Our hunter-gatherer ancestors are huddled around a campfire when they suddenly hear the nearby bushes rustling. They have two options: investigate if the movement was caused by small prey such as a rabbit, or flee, assuming there was a predator such as a saber-tooth tiger. The former could lead to a nutritious meal, while the latter could ensure survival. What call do you think our ancestors would have made?

Evolution ensured the survival of those who fled the scene on the margin of safety rather than those who made the best decision by analyzing all possible scenarios. For thousands of years, humans have made snap decisions in fight-or-flight situations. In many ways, the human race learned to survive by jumping to conclusions.

Study Reveals a Protein’s Key Contribution to Heterogeneity of Neurons

Posted by in category: neuroscience

Summary: Just one protein situated on the synapse can profoundly alter how some neurons communicate and implement plasticity.

Source: picower institute for learning and memory.

The versatility of the nervous system comes from not only the diversity of ways in which neurons communicate in circuits, but also their “plasticity,” or ability to change those connections when new information has to be remembered, when their circuit partners change, or other conditions emerge.

Scientists Develop Wireless-Networks that Allow Brain Circuits to Be Controlled Remotely through Internet

Posted by in categories: biotech/medical, engineering, internet, neuroscience

Wireless implantable devices and IoT could manipulate the brains of animals from anywhere around the world due to their minimalistic hardware, low setup cost, ease of use, and customizable versatility.

A new study shows that researchers can remotely control the brain circuits of numerous animals simultaneously and independently through the internet. The scientists believe this newly developed technology can speed up brain research and various neuroscience studies to uncover basic brain functions as well as the underpinnings of various neuropsychiatric and neurological disorders.

A multidisciplinary team of researchers at KAIST, Washington University in St. Louis, and the University of Colorado, Boulder, created a wireless ecosystem with its own wireless implantable devices and Internet of Things (IoT) infrastructure to enable high-throughput neuroscience experiments over the internet. This innovative technology could enable scientists to manipulate the brains of animals from anywhere around the world. The study was published in the journal Nature Biomedical Engineering on November 25.

Boosting Memory Performance by Finding Amplitude of Brain Waves and Speeding Oscillations

Posted by in category: neuroscience

Summary: Entrainment can safely manipulate brain waves to induce improvements in memory, a new study reveals.

Source: Florida Institute of Technology.

The brain is made of millions of cells called neurons, that send electrical messages to talk to each other in patterns of vertical electric activity called oscillations. By inducing them first, then finding the amplitude of the specific brain waves is improved during memory, ultimately memory performance itself is boosted. Once introduced, what if a person can boost the speed of these oscillations to improve memory? A university study in a journal for adolescents may show we can.

Scientists got an animal to breathe without oxygen

Posted by in category: neuroscience

A team of scientists has discovered a technique to keep tadpoles alive despite removing their capacity to breathe — by injecting algae into the little froglets’ brains, turning their heads a bright, almost neon, green.

What the frog? Plants, such as algae, produce oxygen through photosynthesis. Animals, on the other hand, cannot — we typically use lungs or gills to filter it from the environment.

A New Kind of Cell Discovered in The Heart Seems to Be Critical For Your Heartbeat

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

A new type of cell has been identified in the heart that is linked to regulating heart rate – and the discovery promises to advance our understanding of cardiovascular defects and diseases, once these cells have been more extensively studied.

The new cell is a type of glial cell – cells that support nerve cells – like astrocytes in the central nervous system (the brain and spinal cord). Named nexus glia, they’re located in the outflow tract of the heart, the place where many congenital heart defects are found.

The new cell type was first found in zebrafish, before being confirmed in mouse and human hearts too. Experiments on zebrafish found that when the cells were removed, heart rate increased; and when genetic editing blocked glial development, the heartbeat became irregular.

What Helps the Brain Reach “Flow”?

Posted by in categories: entertainment, neuroscience

In an effort to see what the brain does during flow, Huskey led research looking at how people experience flow while playing a video game. In a paper, which was published in the Journal of Communication this month, more than 140 participants played a video game. Some took part in an experiment while playing a game and self-reported their experiences. Others also subjected themselves to brain imaging so that researchers could look at how their brain functioned during flow.

Flow happens, Huskey said, when activities are engaging enough to fully involve someone to the point of barely being distracted, but not so difficult that the activity becomes frustrating.

Similarly, a video game designed for a child will probably not keep an adult in flow. There must be a balance, he explained. When there’s a balance, the person experiences an intrinsic reward. Things like getting to the next level or earning points matter, but they become secondary. Simply playing the game and experiencing flow is rewarding in and of itself.

Everything we do as living organisms is dependent, in some capacity, on time. The concept is so complex that scientists still argue whether it exists or if it is an illusion. In this video, astrophysicist Michelle Thaller, science educator Bill Nye, author James Gleick, and neuroscientist Dean Buonomano discuss how the human brain perceives of the passage of time, the idea in theoretical physics of time as a fourth dimension, and the theory that space and time are interwoven. Thaller illustrates Einstein’s theory of relativity, Buonomano outlines eternalism, and all the experts touch on issues of perception, definition, and experience.
