July 2019
  • Deborah Talmi of the University of Manchester, Lynn Lohnas of New York University, Nathaniel Daw of Princeton University have developed a mathematical model of how emotion enhances episodic memory (we remember emotional memories in detail even after a long time, while ordinary memories are lost quickly). (paper) Their computer model is based on a theory of memory recall called the temporal context model (TCM), originally presented by Marc Howard and Michael Kahana of Brandeis University ("A Distributed Representation of Temporal Context", 2002), later expanded in the Context Maintenance and Retrieval Model.

June 2019
  • Matteo DeMarco and Annalena Venneri at the University of Sheffield have discovered that blood types influence the substance of the brain. For example, people with an `O' blood type have more "grey matter" in brain, and are therefore less vulnerable to cognitive diseases such as Alzheimer's. (paper).

May 2019
  • Alfredo Fontanini's team at Stony Brook University in New York has developed a metastable model based on a clustered architecture to explain how the brain perceives the world and generates action based on expectation (more than on what is actually out there). The brain's context and expectation influence what animals perceive and how they process such sensory information. This metastable model explains why, for example, the activity in the visual cortex appears to be very similar whether the animal is kept in complete darkness or is walking around in broad daylight: much of the brain's activity, at least within the sensory regions, is generated within those regions themselves rather than driven by the stimuli received by those regions from the outside world (paper).

April 2019
  • A team led by Nenad Sestan of the Yale School of Medicine was able to restore neural activity in the brains of dead pigs (paper).
  • Robert Reinhart and John Nguyen at Boston University are using electricity to stimulate brain regions in the theta-wave range. The electrical stimulation (called "transcranial alternating current stimulation") ensures the kind of rhytmic coupling between the frontal and temporal cortex that is necessary for retrieving memories. The result is an increase within and between frontotemporal regions which corresponds to an increase in the performance of working memory, but the effect lasted only about 50 minutes. (paper)

March 2019
  • The Science of Meditation (Elysium Health)
  • A team led by Athena Demertzi and Enzo Tagliazucchi at the Brain and Spine Institute in France (who in 2012 at the University of Buenos Aires had discovered how to use fMRI for this kind of research) analyzed the different patterns of brain activity in people who are conscious and people who are unconscious (under general anesthesia) and discovered that the brain activity of unconscious states is limited to neighboring regions, whereas the brain activity of conscious states spans distant unconnected regions (paper). Their conclusion is "that consciousness rests on the brainís ability to sustain rich brain dynamics". Tagliazucchi (in 2016 at the Netherlands Institute for Neuroscience) also studied the effects of LSD on increasing global connectivity within brain regions (paper) and also (in 2015 at the Goethe University in Germany) applied the theory of phase transitions in complex systems to the brain transition from unconscious to conscious states (paper).

February 2019
  • Alcino Silva's team at UC Los Angeles discovered that a CCR5-based therapy regularly used on HIV patients, which basically consists in deletion of the CCR5 gene, helps the brain of mice recover motor control after a stroke or after traumatic brain injury. It also seems to make mice generally "smarter", more capable of learning new things. Incidentally, this happens to be the same gene that in 2018 Jiankui He of the Southern University of Science and Technology in Shenzhen CRISPR-edited in the world's first CRISPR-edited babies (paper).

January 2019
  • Emma Threadgold in Linden Ball's laboratory at the University of Central Lancashire in Britain has conducted experiments on people listening to music while performing Compound Remote Associate Tasks (CRATs). The results seem to show that listening to music actually decreases the level of creativity, contradicting the popular belief that listening to music boosts creativity (paper).
