Altered expression of FYN, a gene associated with the production of Tau, was identified in the brains of people addicted to heroin. Findings suggest opioid use can affect the brain in a way that might cause vulnerability in neural systems that can trigger neurodegeneration later in life.
A new study reports herpes virus utilizes ancient RNA to proliferate, mimicking the same process tumors have been found to manipulate. The findings could have implications for new treatment options and also may shed light on neurodegenerative diseases.
For those with a genetic predisposition to higher eye pressure, high caffeine consumption may increase the risk of developing glaucoma threefold.
Heightened states of arousal altered neural circuits in a brain area associated with decision making, resulting in some neurons changing from decision making to internal state monitors.
Neurons derived from stem cells of combat veterans with PTSD react differently to stress hormones than those derived from veterans without PTSD. The findings shed new light on how genetics can cause some to develop PTSD following a traumatic event.
Greater impairment of the prefrontal cortex-habenula pathway was correlated with earlier age of first drug use.
A new study reports impairments in six brain networks are associated with addiction behaviors. The findings may pave the way for developing more targeted treatments for addiction.
Researchers have identified key differences between the way males and females with schizophrenia process the emotional states of others than those without the condition. The study reports those with schizophrenia use less complex brain regions than healthy controls to process other people's emotions.
Researchers have identified a neural mechanism that supports advanced cognitive functions such as planning and problem-solving. The mechanism distributes information from a single neuron to larger neural populations in the prefrontal cortex.
In the largest genetic sequencing study of autism conducted to date, researchers have identified 102 genes associated with the neurodevelopmental disorder. 49 of the genes were also associated with other developmental delays. The new study has enabled the researchers to increase the number of ASD associated genes from 65 to 102.
