Racial Residential Segregation Associated with Lower Cognitive Performance
African Americans who were exposed to segregation in their neighborhoods during young adulthood are more likely to have poor cognitive performance as early as midlife.
Specialized Immune Cells May Improve Early Detection of Parkinson’s Disease
An elevated presence of specialized immune cells were found in patients prior to developing motor symptoms and receiving a diagnosis of Parkinson’s disease, which may help improve early detection.
New Map of Inference-Based Behavior
Both the hippocampus and the orbitofrontal cortex are involved in inference-based behavior, according to a new study.
Unexpected Diversity in Neuronal Spine Projections
Small projections of dendritic spines known as spinules are unexpectedly dynamic, while a stable subgroup may form multi-synaptic spine connections, according to the first detailed study of their behavior.
Mechanism Behind Upper Motor Neuron Degeneration Revealed
Scientists from Northwestern Medicine and the University of Belgrade have pinpointed the electrophysiological mechanism behind upper motor neuron disease, unlocking the door to potential treatments for amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases.
New Neural Connections Between Thalamus and Cortex
A Northwestern Medicine study has identified looped neural connections between the cortex and thalamus, providing a new understanding of connectivity between the two brain regions.
Memory-Related Signaling May Influence Anxiety and Substance Misuse
Neural signaling that encodes certain memories as negative could impact anxiety and substance misuse disorders, according to a recent study.
High Blood Pressure Associated with Cognitive Decline in African American Patients
Higher cumulative blood pressure among African-American patients is a major contributor to their higher risk of dementia, according to a new study.
MSTP Student Explores Mechanisms of Sex Differences in Alzheimer’s Disease
Sky Dominguez, a second-year student in the Medical Scientist Training Program, is currently studying the biological mechanisms underlying a sex difference in Alzheimer’s disease, as approximately two-thirds of those with the disease are women.
