Meet the fungus that makes you see little people.

The fungus is a mushroom called L. ananassa, which is a bolete mushroom (a group with sponge-like pores instead of gills) found in Yunnan, China, the Philippines, & Papua New Guinea. It was only documented in 2015. Locally, it's called Jian shou qing, meaning "turns blue in the hand."It is edible when fully cooked, but undercooking can trigger "Lilliputian hallucinations" (after Gulliver's Travels—vivid visions of tiny people, often 0.8 in tall (2 cm)). The hallucinations are not typical of other hallucinogens like magic mushrooms (psilocybin) or LSD.

Hundreds of people report seeing tiny people marching like soldiers, tiny figures clinging to spoons or swimming in soup. The reason this is scientifically shocking is that scientists have not been able to identify the chemical hallucinogen. Scientists believe the mushroom contains a completely new, unidentified psychoactive compound. The name "see-hand-blue" is because boletes contain compounds that oxidize when exposed to air. When the mushroom is bruised, enzymes break open cells, which react with oxygen & react to form blue pigments. It's like cutting an apple & watching it turn brown, but in the mushroom, the oxygen reaction makes it blue instead of brown.

Whatever the mysterious psychedelic compound is, it is heat-sensitive. Cook it long enough & it breaks apart. But if you eat it lightly sautéed or in a quick stir-fry, the compound survives & causes hallucinations a few hours later. Scientists believe the mystery hallucinogen is connected to the psychedelic's oxidation, which gives it the blue hue, because the psychedelic is created following bruising. It's a bolete mushroom relative with a secret—a mushroom that is rewriting what we think about hallucinogens.

Posting to say im not dead, im just too busy to write comprehensible lab notes 🥀

Yes. Siense.

If this is your first impression of me i am so so sorry 🫡

"...many of our unique mental traits seem to have evolved through the novel deployment of brain structures that originally evolved for other reasons. This happens all the time in evolution. Feathers evolved from scales whose original role was insulation rather than flight. The wings of bats and pterodactyls are modifications of forelimbs originally designed for walking. Our lungs developed from the swim bladders of fish which evolved for buoyancy control. The opportunistic, "happenstantial" nature of evolution has been championed by many authors, most notably Stephen Jay Gould in his famous essays on natural history. I argue that the same principle applies with even greater force to the evolution of the human brain. Evolution found ways to radically repurpose many functions of the ape brain to create entirely new functions. Some of them - language comes to mind - are so powerful that I would go so far as to argue they have produced a species that transcends apehood to the same degree by which life transcends mundane chemistry and physics."

"In terms of the perception of time, many physicists would argue that the perception of time, the flow of time—that the past is no longer real, the present is real, and the future is not yet real—is an illusion, or a mental construct, or something imposed by the brain. And this is the debate between what we call eternalism, or the block universe, and presentism. So under eternalism, the past, present, and future are equally real. And under presentism, only the present is real. And that's how we perceive. And this is the fundamental debate about what's the nature of time. And there's this ongoing debate where the physicists say, "Hey, you neuroscientists figure this out, because obviously time is not flowing. Why does it feel like it's flowing?" And then the neuroscientists say, "Well, you physicists figure this out, because, you know, time is flowing." But the physics is really mostly the interpretation in which, because of relativity, the physics doesn't have a specific point—"you are here" doesn't say there's anything special over here. The equations of physics are time-symmetric, or time-reversible. So that leads to one interpretation: that the past, present, and future are equally real, much like space. You can be anywhere in space; you can be any moment in time.

But I've argued that I think the brain is telling us something true about the physical universe—that it is because we've evolved to survive in a universe governed by the laws of physics, in a mesoscopic part of that universe, not at the micro, not at the cosmo, but at the mesoscopic level, to survive in this world governed by the laws of physics. So I think, and have argued this point, that it is really flowing, and our brain creates this conscious perception of the flow because it's a real part of what we experience, and of the universe."

Brain Anatomy

Central Sulcus

Also known as the Rolandic fissure, is a prominent area of the cerebral cortex that separates the precentral gyrus of both the frontal and parietal lobes and plays a key role in motor and sensory processing.

Limbic lobe

Helps control our emotions, behaviour, and memory and contains highly important areas such as the hippocampus, amygdala, parahippocampal gyrus and the cingulate gyrus. Dysfunction in this area of the brain is linked with anxiety disorders, PTSD, Alzheimer’s disease and epilepsy.

Parietal lobe

Processes sensory information from the body thus allows us to feel stimuli such as pain and pressure, also serves as the primary sotamosensory cortex which processes sensory information.

Parieto-occipital sulcus

The medial surface of the brain, separates the occipital and partial lobes and is crucial in neuroanatomy for helping scientists & medical professionals know the boundaries between the two lobes.

Occipital lobe

Is responsible for the processing of visual information and contains the primary visual cortex and the visual association areas,

Pineal gland

A small pine-cone shaped endocrine gland located deep in the brain between the two hemispheres, this gland produces the hormone melatonin.

Corpora quadrigemina

Consists of two pairs of round colliculli named the superior and inferior colliculi. The superior helps with visual reflexes whilst the Inferior helps with audio processing.

Aqueduct of the midbrain

Also known as the cerebral aqueduct, is a narrow channel that connect the third and fourth ventricles and allows cerebrospinal fluid to flow between the ventricles.

Fourth ventricle

A fluid-filled cavity located between the cerebellum and brain stem, is filled with cerebrospinal fluid.

Cerebellum

Located at the back of the brain beneath the occipital lobes, it coordinates balance and voluntary movement and plays a role in advanced motor activity.

Pons

Sits above the medulla oblongata and below the midbrain and is part of the brainstem, acts as a connection between different brain regions relaying signals to the cerebellum and spinal cord, also regulates sleep and breathing.

Medulla oblongata

The lowest part of the brainstem, connects the brain to the spinal cord and controls vital autonomic functions such as heart rate and blood pressure.

Mammillary body

Small, round structures on the underside of the brain which are part of the limbic system, are involved in memory and emotional processing.

Temporal lobe

Located on both sides of the brain just below the lateral sulcus, involved with audio perception, language comprehension and the formation of memories.

Optic chasm

The point where the optic nerves from each eye partially cross, this crossing allows the visual information from each eye to be processed by the both hemispheres

Hypothalamus

Small structure located underneath the thalamus, regulates homeostasis and autonomic functions

Thalamus

A large area of grey matter that acts as a relay station by processing and motor and sensory information to the cerebral cortex

Corpus callosum

Thick band of nerve fibres that connect the two hemispheres and allows communication between the two hemispheres.

Frontal lobe

The largest part of the brain and is located behind the forehead, is responsible for higher cognitive functions such as decision making, emotional regulation and personality.

Postcentral gyrus

Located in the parietal lobe behind the central sulcus and contains the primary somatosensory cortex and processes somatic sensations.

Would you recognize this person if you saw them in public?

Yes, I know who this is and I feel confident that I would recognize them

I know who this is but I’m not sure I would recognize them in person

They look familiar but I’m not sure who they are

I have no idea who this is
