Analyzing the Connection Between Genes, Brain Characteristics, and Behavior

Intelligence is presumably heritable. Certain genetic variations have been linked to higher intelligence test performance in research. Other research has linked intelligence to a number of brain characteristics, like network efficiency.

Learning how the brain makes choices could help better understand neurological disorders

New research published by investigators at Cedars-Sinai advances scientific understanding of how the brain weighs decisions involving what people like or value, such as choosing which book to read, which restaurant to pick for lunch-;or even, which slot machine to play in a casino.

Brain scans link signs of cellular aging to symptoms of Alzheimer’s

According to a new study led by Anya Topiwala of Oxford Population Health, a division of the University of Oxford in the United Kingdom, and published on March 22nd, 2023 in the open-access journal PLOS ONE, changes in the brain caused by Alzheimer’s disease are connected to telomeres shortening, the protective caps on the ends of chromosomes that shorten as cells age.

Research reports distinct patterns of reward-seeking behavior between OCD and problem gambling

Shinsuke Suzuki at The University of Melbourne, Australia reports distinct patterns of reward-seeking behavior between obsessive compulsive disorder (OCD) and problem gambling, in a study publishing in the open access journal PLOS Biology on March 14th. OCD is associated with lower-than-normal learning rates when rewards are less than expected. On the other hand, people with problem gambling exhibit boosted and blunted learning from rewards higher and lower than expected, respectively.

Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.

DZNE scientists discover major role of centrosome in neuronal migration

Researchers from the DZNE have solved an important puzzle in neurobiology: the wiring and the movement of nerve cells are interwoven, but separately controlled.

New ways to diagnose learning and memory disorders

By showing Welles's movie "Touch of Evil" to mice, Chinmay Purandare, PhD, and Prof. Mayank Mehta of UCLA have uncovered surprising and important new insights about how neurons form memories. The discovery points to new ways to diagnose Alzheimer's and other learning and memory impairments, while also improving artificial intelligence.
