Once a friend I used to regard as very intelligent told me that LSD made his senses extremely sharp and strong, so much so that one could hear people talk from a few miles away. I was astonished that he could be so delusional that his LSD trips were a reality for him, and I naturally lost quite a bit of respect towards his capacity to interpret life 🙂 However, I was intrigued as to the jumbling of one’s brain signals by this controversial drug, and I researched it a bit, to understand how it affects our brains.
Also called psychedelics, hallucinogens alter a person’s perception, mood and a slew of other mental processes. Research has suggested they primarily do their magic in the brain’s cortex, where the drugs activate specific receptors that are normally triggered by serotonin. In order to function, the cortex is integrating different signals, for example glutamate signals and serotonin signals. And what hallucinogens must be doing is they are disrupting this process so that sensory perception is altered by them.
And now, the first study* of LSD and language in decades finds that the drug makes similar concepts compete for attention. It may make it easier for the brain to access distantly related words, by activating certain language networks in the brain. This may explain the giant leaps and associations an LSD user can make from one word to another. Then again, so does practicing meditation, for a first-timer 😉 However, I think this might also explain how my friend thought he developed superman hearing skills -his auditory sensors were gathering info from his leashless language networks.
The study didn’t address questions about the effect of the psychedelic drug on creativity or mental health, but could lead to new research in those areas.
In my opinion, nothing that alters the chemistry of our brains so drastically may be totally harmless. Take it from a person who has seen what too many puffs can do to her friends after some years of smoking pot -which is nothing compared to LSD.

I loved watching and learning, so I wanted to share this:
The question of how life got its start on Earth is a tricky one. Life as we know it needs a genetic mechanism like DNA or RNA to record blueprints for proteins, but proteins are required for the replication of DNA in the first place — and none of that is likely to happen without a cell membrane made of lipids to keep unwanted chemicals out. Biologists have argued for years over which of these three systems might have emerged first, but new research suggests a radical solution to the chicken-and-the-egg conundrum: All three developed at once.
John Sutherland and his team at the University of Cambridge show in a paper published this week in Nature Chemistry that all the elements and energy to create the three systems would have been present in the primordial soup of early Earth. The research shows how the common compounds hydrogen sulfide and hydrogen cyanide, in a bath of UV light and water, could morph into dozens of nucleic acids and lipids. With all the building blocks formed simultaneously, the rest of the process was free to take place.
Perhaps the one prominent theory discounted by Sutherland’s work is exogenesis, the idea that life may have been brought to Earth by a meteor or other celestial object. But even that gets a nod: Meteoric bombardment would have helped supply hydrogen cyanide, iron and other essential elements.
Here is a new perspective… I really like this one, as it gives you an idea within our brains’ everyday measurement brackets. And it is fun,too. I kind of felt sorry for Mercury, though -it totally had a change of image after the “peppercorn” analogy.:)

I recently read an article about the developments in our understanding of how life emerged. The related research was published Nature magazine.
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Aside from illuminating one possible path for life’s beginnings, the achievement is likely to yield a powerful tool for evolving new and useful molecules.
We are one more step closer to unveiling a mystery…. Nice!
‘We like to think we are rational human beings.
In fact, we are prone to hundreds of proven biases that cause us to think and act irrationally, and even thinking we’re rational despite evidence of irrationality in others is known as ‘blind spot bias’.
The study of how often human beings do irrational things was enough for psychologists Daniel Kahneman to win the Nobel Prize in Economics, and it opened the rapidly expanding field of behavioral economics. Similar insights are also reshaping everything from marketing to criminology.”
