In rats, experiments have established that after a few seconds, consciousness is lost. What’s more, the study did not answer my basic question: how long does it take after the cessation of oxygen supply to the brain for the essential neural activity to disappear? The study only reported on brain activity recorded over a period of about 15 minutes, including a few minutes after death. However, such coupling is not uncommon in the healthy brain – and does not necessarily mean that life is flashing before our eyes. “Given that cross-coupling between alpha and gamma activity is involved in cognitive processes and memory recall in healthy subjects, it is intriguing to speculate that such activity could support a last ‘recall of life’ that may take place in the near-death state,” they write. The researchers discovered that some brain waves, called alpha and gamma, changed pattern even after blood had stopped flowing to the brain. While this was the first publication of such data collected during the transition from life to death, the paper is highly speculative when it comes to possible “experiences of the mind” that accompany the transition to death. But a recent paper examined electrical brain activity in an 87-year-old man who had suffered a head injury in a fall, as he passed away following a series of epileptic seizures and cardiac arrest. It isn’t easy to get permissions to study what actually goes on in the brain during our last moments of life. On the contrary, someone who has a protracted history of a serious illness might be more likely to get a rough ride. Some people, having undergone anaesthesia while in good shape or having been involved in a sudden accident leading to instant loss of consciousness have little ground to experience deep anxiety as their brain commences to shut down. One key limitation of studies looking into such experiences is that they focus too much of the nature of the experiences themselves and often overlook the context preceding them. Such an event has been associated with out-of-body experiences, a sense profound bliss, a calling, a seeing of a light shining above, but also profound bursts of anxiety or complete emptiness and silence. Could there be anything of my beloved brother’s mind left to hear my voice and generate thoughts, five hours after he had passed away? Some scientific experimentsĮxperiments have been conducted in an attempt to better understand reports from people who have had a near death experience. Then, deterioration reaches a point of no return and core consciousness – our ability to feel that we are here and now, and to recognise that thoughts we have are own own – is lost. What can brain waves really tell us? ShutterstockĪnd I did, despite 25 years of studying the human brain and knowing perfectly well that about six minutes after the heart stops, and the blood supply to the brain is interrupted, the brain essentially dies. Only he was not breathing anymore and he was cold to the touch. An hour later, I found him perfectly still and beautiful, his head slightly turned to the side as if he was in a deep state of sleep. But when I landed, I was told my brother had passed away four hours ago. I set off to Marseille, France, having been summoned to Avignon by my mother because my brother was in a critical state, a few days after being suddenly diagnosed with terminal lung cancer. On June 14, 2021, I was violently reminded of these questions. Words I remember to this day were the last of Georges Danton on April 5, 1794, who allegedly said to his executioner: “Show my head to the people, it is worth seeing.” Years later, having become a cognitive neuroscientist, I started wondering to what extent a brain suddenly separated from the body could still perceive its environment and perhaps think.ĭanton wanted his head to be shown, but could he see or hear the people? Was he conscious, even for a brief moment? How did his brain shut down? I had just discovered gruesome aspects of the French revolution and how heads were neatly cut off the body by a Guillotine. The first time I reached past the sheer horror of the concept of death and wondered what the experience of dying may be like, I was about 15.

Like, she was obviously manipulating Elina, but I think she would in fact have given her the wings, and that she actually wanted Elina by her side. Now here’s what I find interesting, I think Laverna was being honest here.“You have the rainbow in your eyes that makes you a lot like me” Laverna is gay confirmed.“Let my friends go, Laverna! They don’t have anything you want!” “Not true! They have your love.” Laverna, say that again slowly.This whole commentary is just me going “these two are gay” and “god, I wish that were me”.I have now decided that Dahlia and Laverna were exes.Also, Topaz went from being scared of Laverna, to having muffins with Laverna, to being into Laverna.Like, she only reciprocates when she wants to mess with her And Azura kinda reciprocates but kinda doesn’t, it’s weird. Laverna CANNOT stop flirting with Azura for the life of her.Dahlia was such an interesting and cool character, I wish she showed up in the other fairytopia movies.I want a little butterfly necklace like that too.Elina holding onto Azura’s necklace for comfort ❤.And to think that their little swimming date was gonna lead to an entire movie in the future.I do love how the message of this movie isn’t “Elina is just as capable as everyone else despite being different”, but instead “Elina’s differences are what make her uniquely capable in a way that nobody else is”.The way they’re talking about the “sleeping little fairy girl” makes it sound like Laverna thinks Azura and Elina hooked up and Azura is trying to deny it.“Do you always keep your party guests captive, Laverna?” “As a matter of fact, yes!”.Rewatching this movie is just making me realise how much better my life would be if I was small enough to fit inside a flower.“For the friends you haven’t met!” “And for the ones I have…” I love her so much.Azura was Elina’s gay awakening, change my mind.Elina is already so enamored with Azura, she’s spent the whole time they’ve known each other just longingly staring at her and taking in her every move.Best comfort character ever, throw a tea party for me Azura, please Lesbian aunt Azura realises Elina is a younger lesbian trying to find her purpose and immediately throws her a tea party to tell her how great she is.We all agree that the rainbow eye thing is a metaphor for being gay, right?.Fun fact, Azura is actually my favorite character from all of the Barbie movies.I wanna fly around in a little flower parachute….Funny how Ruby, the only male character who properly interacts with Laverna, is the only one she doesn’t flirt with.She’s almost flirting with Topaz here, and you can tell she wants her to like her so bad.The hyper sweet way Laverna talks to people in this movie makes her so much better and scarier than the villains who just treat everyone with disdain all the time.This is honestly the best villain intro in the BCU and one of the best scenes of the entire movie.Like, they don’t just think she’s dead or missing, they think she full on isn’t real. I’ve always wondered how exactly people started getting the idea that Laverna didn’t exist.Like, she isn’t thrown into the plot, she hears some gossip about it and then decides to participate.I love that the way Elina learned about the main conflict wasn’t through a call to action or a magical prediction, but through hearsay.Setting up that Elina has good aim early on, we love good foreshadowing.This is the most whimsical Barbie movie.

During the Cold War, Europe was divided along the Iron Curtain between NATO in the West and the Warsaw Pact in the East, until the Revolutions of 1989, the fall of the Berlin Wall, and the dissolution of the Soviet Union. Both world wars began and were fought to a great extent in Europe, contributing to a decline in Western European dominance in world affairs by the mid-20th century as the Soviet Union and the United States took prominence. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to radical economic, cultural and social change in Western Europe and eventually the wider world. The Age of Enlightenment, the French Revolution, and the Napoleonic Wars shaped the continent culturally, politically and economically from the end of the 17th century until the first half of the 19th century. Since the Age of Discovery, led by Spain and Portugal, Europe played a predominant role in global affairs with multiple explorations and conquests around the world.īetween the 16th and 20th centuries, European powers colonised at various times the Americas, almost all of Africa and Oceania, and the majority of Asia. The Italian Renaissance began in Florence and spread to the rest of the continent, bringing a renewed interest in humanism, exploration, art, and science which contributed to the beginning of the modern era. The fall of the Western Roman Empire in 476 CE and the related Migration Period marked the end of Europe's ancient history, and the beginning of the Middle Ages. Further from the sea, seasonal differences are more noticeable than close to the coast.Įuropean culture is the root of Western civilisation, which traces its lineage back to ancient Greece and ancient Rome. The European climate is largely affected by warm Atlantic currents that temper winters and summers on much of the continent, even at latitudes along which the climate in Asia and North America is severe. Europe had a total population of about 745 million (about 10% of the world population) in 2021 the third-largest after Asia and Africa. Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Įurope covers about 10.18 million km 2 (3.93 million sq mi), or 2% of Earth's surface (6.8% of land area), making it the second-smallest continent (using the seven-continent model). Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish straits. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. It shares the continental landmass of Afro-Eurasia with both Africa and Asia. ^ "Europe" as defined by the International Monetary Fund.Įurope is a continent comprising the westernmost peninsulas of Eurasia, located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Istanbul is a transcontinental city which straddles both Asia and Europe. ^ Figures include only European portions of transcontinental countries.

MDMA acutely induces feelings of well-being, love, empathy, and prosociality, and produces mild perceptual alterations that are thought to be primarily mediated by the release of serotonin (5-HT) and norepinephrine, and the direct activation of 5-HT 2A receptors. MDMA not only exhibits some amphetamine-like properties but also shows hallucinogenic-like effects and can be considered an intermediate substance between a pure stimulant like d-amphetamine and a pure hallucinogenic drug like LSD. 3,4-Methylenedioxymethamphetamine (MDMA) is the active compound in the recreational substance ecstasy and is currently investigated as an adjunct to psychotherapy to treat post-traumatic stress disorder (PTSD). For example, greater psilocybin-induced mystical-type experiences and more pronounced and more positive acute alterations of consciousness were associated with lasting antidepressant responses in patients with depression. Recent clinical trials indicate that the quality of the acute psychedelic experience in response to psilocybin or LSD predicts long-term changes in mental health and well-being in patients and healthy persons. LSD acutely induces marked alterations of waking consciousness that have been shown to primarily depend on an interaction with the serotonin 5-hydroxytryptamine-2A (5-HT 2A) receptor, although LSD also acts on 5-HT 1 and dopamine receptors. Lysergic acid diethylamide (LSD) is a classic serotonergic hallucinogen that has been widely used recreationally and to a limited extent in psychiatric research. These results indicate clearly distinct acute effects of LSD, MDMA, and d-amphetamine and may assist the dose-finding in substance-assisted psychotherapy research. None of the substances altered plasma concentrations of brain-derived neurotrophic factor. MDMA but not LSD or d-amphetamine increased plasma concentrations of oxytocin. d-Amphetamine increased ratings of activity and concentration compared with LSD. MDMA produced greater ratings of good drug effects, liking, high, and ego dissolution compared with d-amphetamine. LSD also induced greater impairments in subjective ratings of concentration, sense of time, and speed of thinking compared with MDMA and d-amphetamine. LSD also produced greater subjective drug effects, ego dissolution, introversion, emotional excitation, anxiety, and inactivity than MDMA and d-amphetamine. LSD induced significantly higher ratings on the 5 Dimensions of Altered States of Consciousness scale and Mystical Experience Questionnaire than MDMA and d-amphetamine. LSD and MDMA increased heart rate more than d-amphetamine, and d-amphetamine increased blood pressure more than LSD and MDMA. All of the substances produced comparable increases in hemodynamic effects, body temperature, and pupil size, indicating equivalent autonomic responses at the doses used. We investigated the acute autonomic, subjective, and endocrine effects of single doses of LSD (0.1 mg), MDMA (125 mg), d-amphetamine (40 mg), and placebo in a randomized, double-blind, cross-over study in 28 healthy subjects. However, differences in acute responses to these prototypical psychoactive substances have not been characterized in a controlled study. All three substances induce distinct acute subjective effects. LSD and MDMA are being investigated as medications to assist psychotherapy, and d-amphetamine is used for the treatment of attention-deficit/hyperactivity disorder. All three substances are used recreationally. Lysergic acid diethylamide (LSD) is a classic psychedelic, 3,4-methylenedioxymethamphetamine (MDMA) is an empathogen, and d-amphetamine is a classic stimulant. |
