The Filter You Didn’t Choose

This is the second post in a series leading up to the 16th annual International Forum on Consciousness, taking place in Madison this May, hosted by the BTC Institute, Promega and Usona Institute. The Forum gathers scientists, philosophers, and practitioners from dozens of different fields to investigate the nature of the mind. This year’s theme, “Unspoken Intelligence,” explores forms of perception and knowing that fall outside conventional cognition.

When she thought about a dog, she saw a dog, more specifically, every dog she had ever encountered, cycling through her mind like a card catalog with pictures attached. She assumed everyone did this. When she discovered they didn’t, that most people access something more like an abstract concept hovering somewhere between language and image, she was genuinely surprised. Temple Grandin had always known her mind didn’t work the way people expected. What she didn’t know, until she was an adult, was the specific shape of the difference.

Most of us know this story, or one like it. We understand that some minds filter experience differently, but the science on this doesn’t stop where the conversation usually does.


For most of its history, the field that mapped minds like Grandin’s looked at those that didn’t fit the available systems and concluded the minds were broken. (It didn’t ask whether the systems were.) More recently, the conversation has been reframing those minds not as deficient but as different.

For many people, that reframing has been transformative, changing how educators teach, how clinicians diagnose, and how workplaces are designed. We are now more familiar with alternative cognitive profiles such as autistic pattern recognition (like that experienced by Grandin), ADHD-associated divergent thinking, and the hyper-focused depth of what researchers call monotropic attention. These are not broken versions of normal cognition. They are different architectures, each with genuine capabilities that other minds aren’t built to produce.

The terms most commonly used to describe these differences, neurotypical and neurdivergent, are useful shorthand but they describe a binary the underlying biology doesn’t support. Cognitive traits distribute across a population the way most biological traits do. “Neurotypical” minds are simply closer to the statistical center. What we call “neurodivergent” can be better understood as the part of that population that differs visibly enough from the statistical center to make the variation impossible to ignore.

Monoamine Oxidase and Mental Health: From Psychedelics to Diet

Kiwi fruit are thought to contain compounds that naturally inhibit monoamine oxidase

Public awareness of mental disorders has increased over the past decade. Post-traumatic stress disorder (PTSD), anxiety and depression are both debilitating and complex to approach therapeutically. Recent research has begun exploring monoamine oxidase (MAO) enzymes as potential treatment options. MAO enzymes are responsible for the metabolism of monoamine neurotransmitters in the central nervous system, such as serotonin and dopamine (Jones & Raghanti, 2021). Abnormal levels of these neurotransmitters within the nervous system are a key characteristic of several neurological conditions. Thus, exploring MAO regulation may help our understanding of these complex clinical conditions.

Psilocybin as Antidepressant: Quick Acting, Lasting Benefits

Depression is not simply a mood disorder, a feeling of sadness, or being ill at ease. Depression can completely shut a person down, manifesting as an inability to make decisions, to take action, to think. Even sleep is affected by depression.

Researchers and clinicians who treat depression are learning that the physical manifestations can be mirrored by internal, cellular changes. Some people with depression have decreases in their gray matter volume, particularly in areas like the hippocampus (important to memory, learning, and emotions) and prefrontal cortex (where higher-level thought and planning abilities are based).

Additionally, imaging has shown a decrease in the number of synapses—the structures through which electrical or chemical signals are passed between neurons and other cells—in persons with chronic depression. Without the signals that synapses transmit, brain function is disrupted.

And without intervention in depression, synapse decrease can continue.

While there are drugs and behavioral therapies to treat depression, these therapies can be slow to act and sometimes ineffective. In addition, once synaptic loss has occurred, these therapies are less effective.

In their August 2021 paper, “Psilocybin induces rapid and persistent growth of dendritic spines in frontal cortex in vivo” (1), Shao et al. state,

“It has long been recognized that these compounds (serotonergic psychedelics like psilocybin) may have therapeutic potential for neuropsychiatric disorders, including depression, obsessive-compulsive disorder and addiction”.

10 Surprising Facts About Hallucinogens, Psychedelics and “Magic Mushrooms”

The BioPharmaceutical Technology Center Institute, which is located at Promega Corporation in Madison, Wisconsin, recently hosted the 10th Annual International Bioethics Forum titled “Manifesting the Mind”. Several notable speakers gave presentations on a rather unexpected subject matter: the use of hallucinogens such as psilocybin (i.e., magic mushrooms) to better understand the nature of consciousness and to even treat neuropsychological disorders such as depression, anxiety and drug addiction. I was one of the lucky participants that attended this forum.

Unlike scientism, science in the true sense of the word is open to unbiased investigation of any existing phenomena.
