May 28th 2024, 17:43

Researchers have demonstrated how B cells infected with the Epstein-Barr virus (EBV) can contribute to a pathogenic, inflammatory phenotype that contributes to multiple sclerosis (MS); the group has also shown how these problematic B cells can be selectively targeted in a way that reduces the damaging autoimmune response of multiple sclerosis.

May 28th 2024, 17:43

Music and speech are among the most frequent types of sounds we hear. But how do we identify what we think are differences between the two? An international team of researchers mapped out this process through a series of experiments -- yielding insights that offer a potential means to optimize therapeutic programs that use music to regain the ability to speak in addressing aphasia.

May 27th 2024, 11:59

Researchers made a significant breakthrough in Alzheimer's disease research by identifying a novel way to potentially slow down or even halt disease progression. The study, which focuses on the role of reactive astrocytes and the plexin-B1 protein in Alzheimer's pathophysiology, provides crucial insights into brain cell communication and opens the door to innovative treatment strategies.

May 22nd 2024, 13:03

Researchers have found that a specific pattern of brain activity, known as 'sharp-wave ripples,' is associated with thoughts that wander from the present situation. This activity begins in the hippocampus, a crucial brain region for memory formation and recall, and is linked to more vivid and less desirable thoughts. A better understanding of the relationship between sharp-wave ripples and these kinds of thoughts might be helpful for treating related conditions.
