Have you ever wondered how speech is processed differently from other sounds in the brain? Anni Nora of Aalto University et al. did. Explore their research: https://bit.ly/2RB3ZUV #neuroscience

Interesting findings: The degree of motivation and the stamina to keep it up depends on the ratio between the neurotransmitters glutamine and glutamate in the nucleus accumbens of the brain.

The same neuroimaging (fMRI) data set on a decision making task with 9 hypotheses analyzed by 70 independent teams brought scientists to almost no consensus. This poses so many questions and challenges to the neuroimaging and neurosciences methods. What do you think really contributed to this? Is it about the expert knowledge? Or Is it the replication crisis or flaws in the data analysis methods? Cognitive Neurosciences being a young field still has to achieve many mileston...es. How this crisis can be effectively handled? What directions actually the scientists of the filed need to take? Or the dateset of 108 brain scans analyzed by these 70 teams in itself is not enough to bear such conclusions to the whole field? Explore two sides to the coin! Full text pre-print https://www.biorxiv.org/content/10.1101/843193v1.full.pdf Original paper: https://www.nature.com/articles/s41586-020-2314-9

Scientists at EPFL have developed a new method based on genome-scale metabolic models, or GEMs that simplifies the processing of genetic-metabolic data by picking up changes in metabolism, a hallmark of numerous diseases like cancer and Alzheimers. The new method, named redHUMAN, is robust and features guaranteed predictability. Full text: https://www.nature.com/articles/s41467-020-16549-2.pdf... Credit: Maria Masid et al.

Did you ever wonder what happens to memory in Alzheimers disease? Researchers in a recently published article described that the memory traces still remains there, but impaired by interference with other neuronal ensembles. Like a noisy radio channel.
