How We Filter Out Background Sounds When Speaking

Researchers have traced how the brain filters out background noise during speech using signals between the motor and auditory cortices. These milliseconds-long electrical signals, called auditory corollary discharge, originate in the motor cortex's precentral gyrus and travel to the auditory cortex's superior temporal gyrus.

Violence Exposure and Firearms Linked to Teen Suicide Risks

A study of U.S. high school students reveals a strong link between suicidal behavior, externalizing behaviors (such as physical violence), and exposure to violence. Adolescents with a history of weapon carrying or engaging in violent acts were found to have a higher risk of injurious suicide attempts, particularly when firearms are accessible.

Masculine Ideals Double Suicide Risk in Men

Men who strongly adhere to traditional masculine ideologies, such as suppressing emotions and valuing independence, are more than twice as likely to attempt suicide compared to those with more egalitarian views. The study identified three groups of men—Egalitarians, Players, and Stoics—with Stoics being at the highest risk due to their attitudes and behaviors, especially during mental health crises.

Family History of Mental Illness Increases Aggression Risk in CTE

A new study reveals that individuals with chronic traumatic encephalopathy (CTE) and a family history of mental illness have a heightened risk of aggression during adulthood, particularly between ages 40 and 59. Researchers analyzed data from 845 men with histories of head injuries, finding that those with both CTE and a family history of mental illness displayed significantly more aggressive behaviors than those with only one risk factor.

Depression Linked to Increased Menstrual Pain

Depression may increase the risk of menstrual pain, or dysmenorrhea, through mechanisms such as sleep disturbances. Using genetic analysis, researchers found that depression likely causes period pain, rather than the reverse, highlighting an underexplored connection between mental and reproductive health. The study suggests that addressing sleep issues and mental health could improve treatment for severe menstrual pain.

Fitness Trackers Detect Mood Episodes in Bipolar Disorder with High Accuracy

Data from fitness trackers can detect mood episodes in individuals with bipolar disorder with up to 89.1% accuracy for mania and 80.1% for depression. Researchers used passively collected, noninvasive data and machine learning algorithms to identify mood changes, demonstrating the potential for real-time monitoring.

Brain Biomarker Could Predict Psychosis Before Symptoms Emerge

Researchers have identified a brain biomarker that may predict psychosis onset before symptoms appear, enabling earlier interventions and personalized care. MRI scans revealed abnormal connectivity patterns in sensory brain networks, with weaker connections between sensory regions and stronger connections to the thalamus.

Can Cannabis Help ADHD?

Researchers are investigating how cannabis affects ADHD symptoms, focusing on its interactions with the body's endocannabinoid system. Evidence suggests cannabis influences attention, hyperactivity, and anxiety, but the findings are limited due to legal restrictions and the complexity of ADHD presentations.

Alcohol Use Predicts Escalating Cannabis Vaping Among Youth

A recent study highlights alcohol as the strongest predictor of cannabis vaping initiation and experimentation among youth and young adults, regardless of demographic factors. Conducted over three years, the research found that alcohol consumption increased the likelihood of transitioning from non-use to cannabis vaping.

Our “Reptilian” Brain Areas’ Role in Emotion and Social Skills

A new study uncovers constant communication between the human brain's social cognitive network, responsible for understanding others' thoughts, and the amygdala, known for processing fear and emotions. High-resolution brain scans revealed that this connection helps the brain integrate emotional importance into social interactions.

Brain Mapping Approach Reveals Hidden Clues to Schizophrenia

A new study identifies previously hidden brain network patterns in schizophrenia by focusing on nonlinear connectivity, offering potential biomarkers for early diagnosis. Traditional imaging methods often overlook these patterns, but researchers developed advanced statistical tools to uncover this new dimension of brain organization.

Cannabis Worsens Brain Connectivity Deficits in Psychosis Risk

Young adults at risk of psychosis show reduced synaptic density, a critical brain connectivity deficit that cannabis use appears to exacerbate, according to new research. The study revealed lower synaptic density linked to social withdrawal and motivational deficits, symptoms poorly addressed by current medications.
