Perfect balance: How the brain fine-tunes its sensitivity      (via sciencedaily.com)     Original source 

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now report how neuronal networks in the mouse brain are fine-tuned.

Scientists uncover 95 regions of the genome linked to PTSD      (via sciencedaily.com)     Original source 

In posttraumatic stress disorder (PTSD), intrusive thoughts, changes in mood, and other symptoms after exposure to trauma can greatly impact a person's quality of life. About 6 percent of people who experience trauma develop the disorder, but scientists don't yet understand the neurobiology underlying PTSD. Now, a new genetic study of more than 1.2 million people has pinpointed 95 loci, or locations in the genome, that are associated with risk of developing PTSD, including 80 that had not been previously identified.

Paper: To understand cognition--and its dysfunction--neuroscientists must learn its rhythms      (via sciencedaily.com)     Original source 

Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level.

Protecting brain cells with cannabinol      (via sciencedaily.com)     Original source 

Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer's, Parkinson's, and traumatic brain injury. Their findings reveal novel aspects of CBN's neuroprotective activity and demonstrate the clinical potential of CBN and value of studying its analogs.

Scientists identify cell vulnerability 'fingerprint' related to Parkinson's, Lewy body dementia      (via sciencedaily.com)     Original source 

A new study offers a first look into the complex molecular changes that occur in brain cells with Lewy bodies, which are key pathological hallmarks of Parkinson's disease and some dementias. The findings reveal that brain cells with Lewy bodies exhibit a specific gene expression pattern akin to a disease-related fingerprint.
