Mice deficient in the NFIA gene presented astrocytes with defective shapes and altered functions in the hippocampus. Read More
Following a meal, astrocytes associated with POMC neurons in the hypothalamus alter their shape. After eating, glucose levels increase temporarily. Astrocytes detect the signal and react within one hour, causing POMC neurons to activate and promote the feeling of satiety. Read More
When autoantibodies are able to enter the bran and act on NMDA receptors, people experience relief from symptoms of anxiety, depression, and stress. Read More
Study explains how an overexpression of the RCAN1 gene may cause intellectual disabilities in people with Down syndrome. Read More
Altering microglia in rats helped enhance their performance in memory tasks by up to 50%. The findings could help to develop new therapies that enhance memory function and prevent cognitive decline in humans. Read More
Microglia, key immune cells in the brain, may play a significant role in memory retention. Read More
A study of the Xhosa, an ancestral African population, sheds light on the genetic origins of schizophrenia. Read More
Low-intensity exercise triggers brain networks associated with cognitive control and attention processing, while high-intensity exercise activates networks involved in emotional processing. Read More
Study identifies a short gene segment crucial for brain development and information processing. The absence of the gene segment induces altered social behaviors, learning difficulties, and memory deficits, which are hallmarks of a subset of ASD. Read More

··4 min readRat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies. Read More
In the largest genetic sequencing study of autism conducted to date, researchers have identified 102 genes associated with the neurodevelopmental disorder. 49 of the genes were also associated with other developmental delays. The new study has enabled the researchers to increase the number of ASD associated genes from 65 to 102. Read More
Critical aspects of hippocampal function can be reversed in old age, or compensated for throughout life, with the help of neural stem cells. Read More
