Mental Fatigue of Multiple Sclerosis Linked to Inefficient Recruitment of Neural Resources

Those with MS allocate neural resources less effectively when faced with increased cognitive task demands, and this likely results in the increased mental fatigue those with the neurodegenerative disorder experience.

Further Evidence World Trade Center Responders Are at Risk for Dementia

First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population.

Adults With Alzheimer’s Risk Factors Show Subtle Alterations in Brain Networks Despite Normal Cognition

APOEe4, a gene associated with Alzheimer's disease risk, doesn't appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.

Discovery of “Thought Worms” Opens Window to the Mind

Researchers have discovered a brain-based marker for new thoughts, reporting people experience more than 6,000 thoughts per day. The study reports a new method that can detect indirectly when one thought ends and another begins.

Is What I See, What I Imagine? The Neural Overlap Between Vision and Imagination

Using artificial intelligence and neuroimaging, researchers have identified a link between mental imagery and vision. The brain uses similar visual areas for mental imagery and vision but uses low-level visual areas less precisely for mental imagery than vision.

Delirium, Rare Brain Inflammation and Stroke Linked to Covid-19

Coronavirus infection can lead to an array of neurological complications, including delirium, stroke, and a rare, often fatal neuroinflammatory condition called ADEM. The neurological complications did not always correlate with the severity of respiratory symptoms. In some patients, brain inflammation was likely caused by an immune response to COVID-19, suggesting the neurological damage may be a result of immune system activation rather than the virus itself.

Brain Structural Elements in Psychiatric Disorders

Comparing data from multiple neuroimaging studies, researchers found shared brain structural abnormalities between four psychiatric disorders, including schizophrenia and bipolar disorder. They also identified brain signatures unique to each condition.

Brain Connectivity in Cannabis Users

Examining the brains of frequent cannabis users, researchers have identified a pattern of connectivity related to craving the substance. The findings add weight to the idea that brain regions do not work in isolation, but via the connectivity of multiple networks that signal to each other depending on state and need. Brain connectivity during cannabis cravings is not static but has fluctuations in connection patterns between the central executive network and nucleus accumbens.

The human brain tracks speech more closely in time than other sounds

Research suggests a time-locked encoding mechanism may have evolved for speech processing in humans. The processing mechanism appears to be tuned to the native language as a result of extensive exposure to the language environment during early development.
