Oral Bacteria May Drive Multiple Sclerosis

Scientists have found that people with multiple sclerosis (MS) have a distinctly imbalanced oral microbiome—marked by a loss of beneficial bacteria and a rise in inflammation-linked microbes. Using advanced genetic and metabolic profiling, researchers revealed that saliva from MS patients also had lower levels of hypotaurine, a molecule that supports antioxidant defense and nerve health.

Huntington’s Gene Enhances Early Brain Growth and Intelligence

A study reveals that the genetic mutation causing Huntington’s disease (HD) enhances brain development and intelligence in early life, but leads to degeneration in adulthood. Children with the HD gene exhibit larger brains and higher IQs than those without the mutation.

How We Recognize Words in Real-Time

A recent study has identified three distinct strategies people use to recognize words: "Wait and See," "Sustained Activation," and "Slow Activation." These strategies were observed in both individuals with normal hearing and those with cochlear implants, revealing that word-recognition processes are highly individualized.

Brain Area Linked to Attention Control Identified

Deep brain stimulation (DBS) in the subthalamic nucleus, a treatment for Parkinson's disease, may influence more than just motor control. This treatment, which mitigates Parkinson's symptoms such as tremors, also appears to affect patients' ability to shift their attention between tasks.

Brain’s Response to Crucial Language Hub Removal: New Insights

A new study provides unprecedented insights into the human brain's response to the loss of a key language hub. During epilepsy surgery, the team recorded brain activity before and after the removal of the anterior temporal lobe, a hub for language meaning.

Mindful Mistakes: How Brains Learn from Errors

A new study reveals the brain's swift response to human errors compared to unintended outcomes. When individuals were tasked with identifying arrow directions, researchers observed the brain differentiating between correct responses followed by unexpected symbols and actual mistakes.

Age-Related Changes in Spoken Word Recognition

A recent study reveals intriguing findings about the efficiency of spoken word recognition across various age groups. Efficiency peaks in individuals in their mid-20s to early-30s and notably begins to decline from the mid-40s, independent of hearing ability or general cognitive function.

Predicting Dementia in Parkinson’s: EEG Might Hold the Key

Data from a single EEG electrode might predict cognitive decline, including dementia, in patients with Parkinson's disease. Researchers discovered that reduced strength of specific low-frequency brain waves, known as delta and theta waves, was strongly linked to cognitive dysfunction in these patients.

Mechanism for Long-Term Memory Storage Identified

A novel protein folding mechanism in the endoplasmic reticulum is essential for long-term memory storage. This mechanism is impaired in tau-models of Alzheimer's disease, but restoring the protein folding mechanism reverses memory impairment associated with dementia.
