NYX-783, a newly discovered drug, helps modulate NMDA receptor function in neurons. The drug appears to be effective at suppressing the return of PTSD symptoms in rodent models.
AI technology helped map out diverse and subjective psychedelic experiences to different brain regions.
Researchers reveal how memories and fear responses can be transmitted through social interactions.
A novel nurturing touch-based therapy called Havening can help reduce distress and improve recovery for those who suffered traumatic experiences.
Risk markers for adverse psychological consequences following traumatic injury share similar core similarities across different populations and countries.
Alterations in synapses may help explain how memories form and why certain types of memories are stronger than others.
Researchers have discovered a link between anxiety behaviors and PTSD to an increase in myelin in the brain's gray matter.
Norepinephrine is locally regulated in the visual cortex. More norepinephrine is released when and where visual information is processed.
Chronic stress accelerates the body's epigenetic clock, however, those that can manage the effects of stress by strengthening their emotional regulation and self-control can slow the process.
Complex PTSD (c-PTSD) occurs as a result of exposure to repeated and prolonged trauma, and affects up to 7.3% of the population. Researchers discuss how c-PTSD differs from PTSD, and provide insight on how the disorder can be treated.
Virtual reality is helping researchers uncover some of the secrets of anxiety. Using VR, study participants were able to distinguish between safe and dangerous environments in a game. However, brain scans of those with anxiety showed increased activity in the insula and dorsomedial prefrontal cortex while in a safe zone, indicating their brains were associating the safe environment with threat or danger.
The severity of PTSD symptoms was associated with fewer risky choices and increased activation of the amygdala. Decreased activity in the ventral striatum, an area of the brain associated with processing positive valence such as reward, predicted more severe PTSD symptoms 14 months post trauma.
