Precise communication of two key memory regions boosts formation of lasting memories

In a new, rare study of direct brain recordings in children and adolescents, a Northwestern Medicine scientist and colleagues from Wayne State University have discovered as brains mature, the precise ways by which two key memory regions in the brain communicate make us better at forming lasting memories.

Communication and interaction between two key brain regions is important to forming memory

A research team led by faculty members at Wayne State University has discovered that communication between two key memory regions in the brain determines how what we experience becomes part of what we remember, and as these regions mature, the precise ways by which they interact make us better at forming lasting memories.

Producing more mRNA COVID vaccines could save 1.5M lives in low/middle-income countries

In a recent study posted to the medRxiv* preprint server, a team of researchers from the United States estimated the benefits of scaling up coronavirus disease 2019 (COVID-19) vaccination in the low- and lower-middle-income countries (LIC/LMICs) amid the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant using economic and epidemiological models linearized with public data of COVID-19 vaccinations and deaths.

Genetically informed brain atlases help identify hundreds of genomic loci

An international team of scientists has used atlases of the human brain informed by genetics to identify hundreds of genomic loci. Loci is plural for locus, and in genetics indicates the physical location of a gene or variant on a chromosome.

Dopamine signaling promotes the development of compulsive reward seeking behavior

Northwestern investigators have discovered that dopamine signaling in the brain's dorsomedial striatum promotes the development of compulsive behaviors in animal models, according to findings published in Current Biology.

Study links COVID-19 inflammatory manifestations in brain lysates to Alzheimer’s Disease markers

In a new study, researchers investigated a link between the body’s inflammatory response to SARS-CoV-2 infection within the neuropathological pathways and tau hyperphosphorylation.

Study reveals brain region that plays vital role in making sure people say words as intended

A region crossing the folded surface of the top of the brain, called the dorsal precentral gyrus, plays an essential role in how people use the sound of their voices to control how they want the words to sound, a new study shows.

Relationship between SARS-CoV-2 neurotropism and Alzheimer's disease

In a new study, researchers evaluated the neurotropism of SARS-CoV-2 and its impact on COVID-19 patients with and without neurological disorders like Alzheimer's disease.

Three different autism risk genes found to have similar effects on brain development

Autism spectrum disorder has been associated with hundreds of different genes, but how these distinct genetic mutations converge on a similar pathology in patients has remained a mystery.

Study helps better understand how the olfactory cortex processes odor information

Neural waves of three distinct registers combine to give the brain a picture of what's being smelled, according to a Northwestern Medicine study published in PLOS Biology.

Study finds abnormal link between autonomic and central nervous systems in patients with generalized anxiety disorder

Researchers at the Laureate Institute for Brain Research (LIBR) in Tulsa, Okla., have identified an abnormal link between the autonomic and central nervous systems, specifically via communication between the heart and part of the brain's frontal cortex, in women with generalized anxiety disorder (GAD).

Rolling brain wave patterns can provide clue to understanding sleep, anesthesia, and attention

While sleeping, the entire brain rolls through long, slow waves of electrical activity, like waves on a calm ocean. Researchers call that state of consciousness "slow wave sleep".

Researchers investigate functional advantages of traveling brain waves during working memory

After more than a century of study, the significance of brain waves – the coordinated, rhythmic electrical activity of groups of brain cells – is still not fully known. An especially underappreciated aspect of the phenomenon is that waves spatially propagate, or "travel," through brain regions over time.

Study reveals potential mechanism for iron accumulation in the aging brain

Breakdowns in regulatory mechanisms cause iron to build up in the brain as organisms grow older, increasing oxidative stress and causing cellular damage, according to a Northwestern Medicine study published in the journal eLife.

New model can localize sounds in the real world

The human brain is finely tuned not only to recognize particular sounds, but also to determine which direction they came from. By comparing differences in sounds that reach the right and left ear, the brain can estimate the location of a barking dog, wailing fire engine, or approaching car.
