Johns Hopkins study explains why MDMA may help treat PTSD

A group of Johns Hopkins neuroscientists have found that the psychoactive drug MDMA crystal for sale near me, or ecstasy, causes a neural response called a “critical period,” when the brain is sensitive to learning the reward value of social behaviours.

The findings, reported Wednesday in Nature, may explain why MDMA may be helpful in treating people with post-traumatic stress disorder. Can You Buy Microdosing Magic Mushroom Capsules Online Maine?

Critical periods were first described by scientists studying snow geese in the 1930s. About 24 hours after a gosling hatches, researchers observed, if the mother goose is nowhere to be found, the hatchling will bond with an object, including non-living ones. Yet, if the mother goose disappears after the critical period ends, about 48 hours later, the hatchling won’t bond to an object.

Since the snow goose study, studies have shown evidence that critical periods smooth the way for the development of language, touch, and vision. For the MDMA Powder for sale study, scientists at the Johns Hopkins School of Medicine wanted to determine whether a critical period exists for learning the rewards associated with social behaviors, and if so, whether the drug could reopen the critical period.

Neuroscientist Gül Dölen and her team studied groups of mice in enclosures with different bedding. They put several mice together in one enclosure with one type of bedding for 24 hours and, in the next 24 hours, put the same mice by themselves in another enclosure with a different type of bedding. The mice began to associate certain types of bedding with isolation or companionship. Then, they let the mice wander between enclosures with the two types of bedding and tracked how long the mice spent in each enclosure. The more time the mice spent in the bedding linked to their companions indicated more social reward learning.

“It’s why people gather around the water cooler,” says Dölen, assistant professor of neuroscience at the Johns Hopkins University School of Medicine. People are conditioned to know that the water cooler is an optimal place to chitchat with companions.

In their experiments, Dölen and her colleagues found that the critical period for social reward learning in mice occurs around puberty and wanes once they become mature adults. To determine if they could reopen the critical period, the scientists gave MDMA to mature mice, waited 48 hours for the drug to be washed out of their system, and observed how the mice explored their enclosure and behaved with other mice in the enclosure. Following the treatment with MDMA, most of the animals responded to social interactions the same way as juveniles, by forming a positive association between social interactions and the bedding. This effect lasted for at least two weeks after the MDMA treatment, and it was not observed in mice given saline injections. How can you Buy Dried Psychedelic mushrooms online Maine?

“This suggests that we’ve reopened a critical period in mice, giving them the ability to learn social reward behaviors at a time when they are less inclined to engage in these behaviors,” Dölen says.

Dölen and her postdoctoral student and first author of the current study, Romain Nardou, also observed that MDMA works to reopen the critical period only if the drug is given to mice when they are with other mice, not if it is given to mice while they are alone. This suggests that reopening the critical period using MDMA may depend on whether the animals are in a social setting, say the scientists. Can You Buy Buy Dried Microdose mushrooms Online Maine?

The mice maintained their ability to learn the rewards of social behavior for up to two weeks from the time they were given MDMA. During this time, Dölen and her colleagues also found that the brains of the mice had corresponding responses to oxytocin, known as the “love hormone,” which is made in the hypothalamus and acts in the brain as a signal between neurons that encode information about social rewards. They found these responses by looking more closely at synapses, the spaces between brain cells called neurons. Their experiments showed that, in mature mice given MDMA, oxytocin triggers signaling in the synapses that encodes learning and memory, which does not typically happen in mature mice.

Dölen says that opening the critical window for social reward behavior may also have implications for treating psychiatric conditions. A strong bond between a psychotherapist and patient is well-known to be important for successful treatment. If MDMA reopens the critical period for social reward learning in humans in the same way it does for mice, then it could explain why the drug has been successful in treating people with PTSD, perhaps by strengthening the psychotherapist-patient bond.

MDMA has been designated by the U.S. Food and Drug Administration as a “breakthrough therapy” for PTSD, meaning that the agency will fast-track the development and review of clinical trials to test it. However, the researchers caution that MDMA may not work for every psychiatric condition linked to social behaviors. Where do I Buy Dried Psilocybin mushrooms Online Maine?

“As we develop new therapies or determine when to give these therapies,” Dölen says, “it’s critical to know the biological mechanism on which they act.”
