Episode 196: The Disappearance of Jacobo Grinberg *IS LIVE*! Image 01: Jacobo Grinberg was a famed Mexican scientist, neurophysiologist, and psychologist who dedicated his life to studying an unseen reality or “Lattice” which existed at the intersection of psychic ability and shamanism. Image 02: Jacobo in the lab. Image 03: One of Jacobo’s experiments tested psychic ability by instructing children to meditate, after which he would blindfold the child and ask them to describe picture books without use of their eyes. Image 03: The experiments led Jacobo to publish his “sintergic theory” about the existence of an unseen reality, or “lattice”, we can tap into with meditation. Image 04: Jacobo theorized that Mexican Shamans were able to tap into the lattice and began observing a Mexican healer known as “La Pachita.” Image 05-08: La Pachita was famous for performing psychic surgeries using only a few bandages and a rusty kitchen knife. During these surgeries, Pachita would connect with a spirit she called “Hermanito” who had been a powerful Aztec ruler known as Cuauhtémoc. Image 09: As Jacobo’s controversial research began revealing things he was “unable to explain with modern science”, Jacobo found himself at the center of political upheaval and was ostracized from the scientific community... until he went missing altogether. Some people believe Jacobo actually transformed into someone else entirely named Shiva Shambo. Image 10: Shiva Shambo. What do you guys think? Where did Jacobo go? Is Shiva Shambo and Jacobo the same person?!
Neurophysiological Symphony: Decoding the Intricacies of Neuronal Action Potentials 🧠⚡️
Salutations, Tumblr scholars! 🎓 Prepare for a cerebral voyage as we delve into the profound intricacies of neuronal communication, spotlighting the ethereal ballet of action potentials! 🌌💫
Introduction:
Neurons, the virtuosos of our nervous system, engage in a sophisticated dialogue facilitated by the nuanced choreography of action potentials. Let us dissect this neurophysiological marvel with precision and finesse. 📚✨
1. The Prelude - Axon Hillock Overture:
Initiation unfolds at the axon hillock, a nexus of decision-making. Voltage-gated sodium channels undergo conformational changes, inducing an influx of sodium ions, thus instigating the critical decision to fire—an orchestration known as the initiation phase. ⚙️⚠️
2. Act I - Depolarization Crescendo:
The ensuing depolarization phase witnesses a surge in membrane voltage, orchestrated by the influx of positively charged sodium ions. This dynamic spectacle disrupts the membrane's resting potential, marking the commencement of the neuronal conversation with unparalleled fervor. 📈🎻
3. Act II - Repolarization Sonata:
Voltage-gated potassium channels, in a harmonious interlude, activate, allowing potassium efflux. Repolarization unfolds gracefully, reinstating the neuron's electrical equilibrium. The meticulous choreography readies the neuron for subsequent engagements. 🚪💨🔄
4. Act III - Hyperpolarization Cadence:
A brief hyperpolarization, an encore of sorts, ensues as potassium efflux persists, momentarily exaggerating the negative membrane potential. This nuanced cadence serves as a poetic pause before the neural narrative resumes. ⬇️🎭
5. Epilogue - Sodium-Potassium Pump Ballet:
In the epilogue, the sodium-potassium pumps elegantly perform their backstage ballet. Sodium is actively extruded, while potassium is ushered back onto the stage, meticulously restoring the resting membrane potential. A harmonious reset concludes this neurophysiological masterpiece. 🔄🔧
Embark on this odyssey through the synaptical intricacies! 🚀🔬

Hi there. Again. That’s my neurographica. If some of you can decipher it, I would be very pleased 😃
Some diagrams I studied for our neuroanatomy module last semester, from Tortora.
The pictures I used for Anki are below.
