Aging: Longer genes may be a main cause, play role in Alzheimer’s

Posted by in categories: biotech/medical, life extension, neuroscience

Scientists say that long genes — which are more susceptible to DNA damage — might be a main cause of the body’s aging and could play a role in. the development of diseases like Alzheimer’s.

Scientists Find Human Brains Are Getting Larger and Larger

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

If someone tells you that you have a big head, take that as a compliment.

Humankind’s brains have apparently gotten bigger and bigger over the years, according to a team of scientists, who are surmising that bigger brains may stave off dementia as folks age.

An international team of researchers, led by the University of California Davis Health, arrived at this finding after studying the MRIs of people starting with those born in the 1930s, all the way through the 1970s.

Japanese scientists discover clue to erasing traumatic memories

Posted by in categories: innovation, neuroscience

Can light be a factor in eliminating traumatic memories? Japanese scientists found that the long-term memory of flies can be affected if they are kept in the dark. This is the first discovery of the role of environmental light on such memories. The scientists hope to extend this approach to human victims of life-affecting traumas.

Events that are shocking can become a part of our long-term memory (LTM), with new proteins synthesized and the neuronal circuits in our brain becoming altered, explains the press release from researchers at the Tokyo Metropolitan University, who made the breakthrough. These memories can be hard to erase and may lead to post-traumatic stress disorder (PTSD).

Through their research, the team led by Professor Takaomi Sakai from Tokyo Metropolitan University discovered a particular molecular mechanism in Drosophilia flies that affects LTM. To find this, they set up a trauma for male flies by placing them with females who already mated. According to the courtship conditioning paradigm, in such situations mated females stress the unmated males to such an extent that they remember the experience, unwilling to ever mate with any more females – even if they were to be exposed to those that are unmated.

Breakthrough Therapy Obliterates Deadly Brain Tumor in Days

Posted by in categories: biotech/medical, neuroscience

Brain scans of a 72-year-old man diagnosed with a highly aggressive form of cancer known as a glioblastoma have revealed a remarkable regression in his tumor’s size within days of receiving an infusion of an innovative new treatment.

Though the outcomes of two other participants with similar diagnoses were somewhat less positive, the case’s success still bodes well for the search for a way to effectively cure what is currently an incurable disease.

Glioblastomas are typically about as deadly as cancers can get. Emerging from supporting cells inside the central nervous system, they can rapidly develop into malignant masses that claim up to 95 percent of patient lives within five years.

What is quantum cognition, and how is it applied to psychology?

Posted by in categories: computing, mathematics, neuroscience, quantum physics

Quantum cognition is a new research program that uses mathematical principles from quantum theory as a framework to explain human cognition, including judgment and decision making, concepts, reasoning, memory, and perception. This research is not concerned with whether the brain is a quantum computer. Instead, it uses quantum theory as a fresh conceptual framework and a coherent set of formal tools for explaining puzzling empirical findings in psychology. In this introduction, we focus on two quantum principles as examples to show why quantum cognition is an appealing new theoretical direction for psychology: complementarity, which suggests that some psychological measures have to be made sequentially and that the context generated by the first measure can influence responses to the next one, producing measurement order effects, and superposition, which suggests that some psychological states cannot be defined with respect to definite values but, instead, that all possible values within the superposition have some potential for being expressed. We present evidence showing how these two principles work together to provide a coherent explanation for many divergent and puzzling phenomena in psychology.

Quantum Cognition: Does it explain irrational decisions?

Posted by in categories: neuroscience, quantum physics

Humans can sometimes be hard to understand, much like quantum physics — unless you watch this channel regularly of course. That’s why a mathematician has come out with an idea of “quantum cognition”. What is this so-called quantum cognition? Does it explain why humans make irrational decisions? Let’s have a look.

Biomolecular Bonsai: Controlling the Pruning and Strengthening of Neuron Branches in the Brain

Posted by in categories: biotech/medical, neuroscience

Researchers identify molecular cues that make developing neurons remodel their connections.

At this very moment, the billions of neurons in your brain are using their trillions of connections to enable you to read and comprehend this sentence.

Now, by studying the neurons involved in the sense of smell, researchers from Kyushu University’s Faculty of Medical Sciences report a new mechanism behind the biomolecular bonsai that selectively strengthens these connections.
