By: Ryan Sumner

I'm Ryan, and I have Autism. From the Spectrum is a podcast about Autism. I am on a mission to explain Autism. Autism emerges in human evolution as a biological adaptation, possibly through neuroplasticity, responding to environmental shifts that harness light’s energy for life. Maybe, people fail to understand how living organisms use the energy from light to drive biochemistry and organize our biology. For each episode, we will discuss various aspects of Autism. At times, we can cover lots of what seems like complex biology and especially neuroscience, but I hope to convey an easy to understand delivery an...

The Art of Medicine Is Dying: Dr. Sabine Hazan on Transforming Autism & Disease Through the Gut
#85
Today at 9:22 PM

Dr. Sabine Hazan is a pioneering gastroenterologist and the first physician to launch a private microbiome testing lab in the U.S. In this powerful episode, she reveals how decades of clinical experience and cutting-edge research have convinced her that the gut microbiome—especially the near-extinction of key bacteria like Bifidobacteria—lies at the root of Autism, Alzheimer’s, cancer, and many chronic diseases. Speaking candidly about the erosion of the doctor-patient relationship, relentless censorship, and the profit-driven forces that have turned medicine into a pill-pushing machine, Dr. Hazan explains why she believes the art of medicine is dying—and how...


Excitatory Neurons: The Brain’s “Go” Signal & Autism
#84
11/12/2025

This episode dives deep into excitatory neurons—the brain’s primary “go” signal—and their outsized role in the Autistic phenotype. We explore how pyramidal neurons, powered by glutamate through AMPA and NMDA receptors, drive lightning-fast information transmission, synaptic hyperplasticity via BDNF, and elevated gamma oscillations (30–80 Hz) in V1, S1, and A1. This overactive excitatory push, paired with reduced parvalbumin and somatostatin inhibition, creates the well-documented E:I imbalance that fuels sensory hypersensitivity, one-trial learning, rigid memory encoding, repetitive behaviors, and the classic distal-connection timing mismatch from early sensory cortices to prefrontal regions.

The Autistic brain gets to the first...


Thalamic Reticular Nucleus (TRN), Sensory Gating & Autism
#83
11/05/2025

Today's episode examines the thalamic reticular nucleus (TRN), a GABAergic structure that filters sensory inputs to the thalamus, influencing sensory processing and attention in Autism. We'll explore how TRN dysfunction contributes to sensory hypersensitivity, repetitive behaviors, and cognitive strengths like visual thinking. We cover the TRN’s visual, somatosensory, auditory, and limbic sectors, using vivid analogies like a security guard and staring contest to illustrate its role. These mechanisms are linked to the Autistic phenotype’s challenges and unique perceptual abilities.

Decoding the Brain: How Reading Works in Autism and Dyslexia
#79
10/01/2025

This week's episode is all about Reading. We will go through the entire process from the moment light hits the retina (50-100ms) to formulating speech (600ms or so). That is, either speaking out loud or silently speaking while reading, a phenomena called subvocalization. We do this when reading to the self. Either way, we speak while reading.

We will compare so called normal readers, the Autistic phenotype, and dyslexia, and at times the odd contrasts of the Autistic phenotype AND dyslexia. Lots of neurobiology, measurement instruments, brain waves (oscillations, frequencies), however, I will hopefully provide easy...

Neurulation, Neuroepithelial Cells, & Mesencephalon
#57
03/17/2025

Why doesn't the MESENCEPHALON further subdivide into larger regions of the brain?

In this episode, we will expand on the neurulation time and focus on the brain formation, spotlighting the proencephalon, mesencephalon, and rhombencephalon, which emerge around days 22–23 of embryonic life. The proencephalon (forebrain) splits into the telencephalon—think cerebral hemispheres for cognition—and the diencephalon, home to the thalamus and hypothalamus for sensory and hormonal control. Meanwhile, the rhombencephalon (hindbrain) divides into the metencephalon (pons and cerebellum, key for movement) and myelencephalon (medulla, handling [mostly] autonomic essentials like breathing). The mesencephalon stands out as a non-subdividing relay...


Autism, Neurulation, and Embryogenesis
#56
03/10/2025

For today's episode, we go into the science of embryogenesis, focusing on neurulation—the critical process where the neural tube forms, laying the groundwork for the central, peripheral, and enteric nervous systems. We discuss how disruptions in this early developmental stage, influenced by factors like folic acid metabolism, the sonic hedgehog pathway, and genes such as PTEN (P10), could shape the autistic phenotype. From cell proliferation to migration, we connect these biological processes to autism, exploring how environmental factors—like a pregnant mother’s exposure to artificial light versus sunlight—might alter developmental outcomes. This episode sets the stage for when...


Part 2 Autism and Sensory Processing: Scientific Literature
