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 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.

New gene may drive earliest brain changes in Alzheimer’s

Genetic analysis of almost 4,300 samples reveals a link between the appearance of amyloid deposits, APOE, and a novel gene called RBFOX1. Lower levels of RBFOX1 in the brain appear to be associated with increased amyloid and global cognitive decline over a person's lifetime.

Even without concussion, athletes in contact sports may have brain changes

Even without a concussion, repetitive impacts experienced by those who play contact sports have clear effects on the brain. Rugby players who reported no concussions had alterations in the microstructure of the brain, specifically in the brain stem. Alterations in the functional organization of the brain were also discovered in MRI images of those who played contact sports.

The molecular mechanisms of depression

Study reveals how the brain's opioid system is linked to mood changes associated with depression and anxiety. Neuroimaging revealed, in those with depression, there is a decreased number of opioid receptors in specific areas of the brain.
