Neuroplasticity at the neuron and synapse level – Neurons sort into functional networks

Neuroplasticity at the neuron and synapse level – Neurons sort into functional networks

Comments 0 Comment

“Individual neurons whose synapses are most likely to strengthen in response to a certain experience are more likely to connect to certain partner neurons, while those whose synapses weaken in response to a similar experience are more likely to connect to other partner neurons,” Friedlander said. “The neurons whose synapses do not change at all in response to that same experience are more likely to connect to yet other partner neurons, forming a more stable but non-plastic network.”

People’s brains store and recall stories the same way

People’s brains store and recall stories the same way

Comments 0 Comment

New scientific findings support the idea that different humans’ brains store and recall story scenes the same way, rather than each person developing unique memory patterns about stories. Also, people generally do well recalling the details of stories. I want to see more targeted research that determines whether information packed in story structures (a person wrestling with a difficult challenge and changing as a result) is more readily and accurately transmitted from brain to brain via storytelling. This would be…

Cognitive bias article of the day: How to Convince Someone When Facts Fail A concise, timely look at how worldview-driven cognitive dissonance leads people to double down on their misbeliefs in the face of challenging evidence. It also recommends steps for having more meaningful conversations with others whose irrational positions differ from your own. 😉

New gene editing method modifies non-dividing cells in brain

New gene editing method modifies non-dividing cells in brain

Comments 0 Comment

Until now, gene editing has relied on cell division to propagate modifications made with techniques like CRISPR Cas9. Researchers at the Salk Institute have devised a new method that can modify the genes of non-dividing cells (the majority of adult cells). They demonstrated the method’s potential by inserting missing genes into the brains of young mice that were blind due to retinitis pigmentosa. After the team inserted fully functional copies of the damaged gene responsible for the condition into the…

Google and others are developing neural networks that learn to recognize and imitate patterns present in works of art, including music. The path to autonomous creativity is unclear. Current systems can imitate existing artworks, but cannot generate truly original works. Human prompting and configuration are required. Google’s Magenta project’s neural network learned from 4,500 pieces of music before creating the following simple tune (drum track overlaid by a human): Click Play button to listen-> Is it conceivable that AI may…
