Neural patterns key to understanding disorders such as PTSD discovered
Imbalanced communication between the hippocampus and amygdala may lead to the inability to distinguish between negative memories that have overlapping features. The findings could provide new treatment options for those with PTSD. ... Read More...
Psychedelic drug MDMA may reawaken ‘critical period’ in brain to help treat PTSD
MDMA, a psychedelic drug, has successfully been used to reopen the 'critical period' of learning the reward values of social behaviors. Researchers report, in mature mice given MDMA, oxytocin triggers signaling in synapses that help encode social learning and memory, a process that does not usually occur in older animals. The findings could help in the development of treatments for PTSD and other disorders.... Read More...
Biology may make certain PTSD patients unresponsive to behavioral therapy
