The best executives I coach aren't blocked by lack of strategy. They're blocked by a nervous system that learned to survive by staying in control. Unlearning that is the actual work.

We ran a pilot clinical trial using electrical brain stimulation to modulate brain rhythms for treatment-resistant depression. 80% of patients responded. I've spent twenty years building toward that number. Next study of this technology will launch soon. Still processing it.

Desire doesn't fade in long-term relationships because people stop caring. It fades because the nervous system stops feeling safe enough to want. That's a neurobiological problem with a clinical solution.

Five kids, one espresso, and a 5:30 AM gym ritual. The neuroscientist in me knows exactly why this works. The dancing part just shows up anyway.

Most people optimize their thinking. Few optimize the nervous system doing the thinking. That's the gap I work in.

1/ My nervous system is contagious. Literally. When I'm dysregulated — rushed, distracted, still in professor mode at dinner — my kids' and wife's brains entrain to mine. I used to think I could hide stress. The hyperscanning data says otherwise. Presence isn't a virtue. It's a physiological act.

Last week, I talked to a great group of educators from @UNCWolrdView about why art isn't a luxury subject. Here's the neuroscience case I made. A thread. 🧵

Brain stimulation, coaching, couples therapy, sex therapy. The espresso holds it all together.

Without giving the body a chance to express, cognitive complexity creates an illusion of control free of actual meaning.

My dancing part balances out the many other parts of me that could be lovingly described as human LLMs.

Sunday evening ritual: 3 questions I ask myself every week that actually change how I operate. A thread. 🧵

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 29/05/2025

One of my favorite findings! We discovered how to literally make people more creative using brain stimulation! 10Hz electrical stimulation to the frontal cortex increased creativity scores by 7.4% in the gold-standard creativity test. 🧵👇

000

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 28/05/2025

We discovered why brain stimulation works for some people but not others! The secret isn't the stimulation itself—it's whether your brain is "tuned in" to the right frequency. This could revolutionize mental health treatment 🧵👇

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 27/05/2025

We discovered that anesthesia doesn't just "turn off" the brain—it reveals how different brain regions have completely different operating systems! 🧵👇

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 26/05/2025

Continuing in the series - next up a paper that was about 10 years ahead of its time - a bit of a hidden gem - worth a first/another look. A detailed investigation of how dual-site stimulation synchronizes networks. Lots of state dynamics and interesting mechanisms of t#ACS.

🧠 Meanwhile, ACh's pronounced but transient effects align with its role in expected uncertainty and attentional processing - temporarily enhancing signal processing without permanent circuit changes. #AttentionNetworks

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 Our findings help explain why NE is often associated with unexpected uncertainty and novel environmental stimuli - its plasticity-inducing effects help neural circuits adapt to important changes in the environment. #CognitiveNeuroscience

100

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 What we found particularly intriguing is that NE induced this plasticity without any artificial stimulation - just spontaneous network activity was sufficient to trigger lasting changes in circuit organization! #SynapticPlasticity

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 Using receptor-specific pharmacology, we determined that CCh's effects were primarily mediated by muscarinic M1 receptors, while NE's long-lasting effects were largely dependent on β-adrenergic receptors. #ReceptorPharmacology

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 In contrast, norepinephrine (NE) produced more complex, bidirectional effects - some neurons increased firing while others decreased. More importantly, NE's effects outlasted its presence, especially in deep cortical layers (V-VI)! #NeuralPlasticity

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 We found that Carbachol (CCh, acetylcholine agonist) caused pronounced but reversible increases in firing rates across multiple cortical layers. The effect was concentration-dependent and disappeared after washout. #Neuromodulation

100

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

🧠 Using multielectrode in vitro arrays, we measured how these neuromodulators affect network activity across different concentrations (1-100μM). Both increase spontaneous firing but with key differences in their temporal profiles! #Neuropharmacology

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 20/05/2025

First up, I am excited to share with you our very first paper that investigated how acetylcholine (ACh) and norepinephrine (NE) differently affect spontaneous cortical activity. These neuromodulators are critical for attention, learning, and behavioral state regulation! #Neuroscience

Your brain doesn't completely shut off these slow waves during wakefulness—they're just much smaller and more localized. When you're tired or not engaged, these waves can increase even while you're awake! #BrainStates

010

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 09/05/2025

As we age, our deep sleep (and those important slow waves) tends to decrease. This may partly explain age-related memory issues. Protecting your sleep quality could be one key to maintaining cognitive health! #AgingBrain #SleepHealth

010

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 08/05/2025

Sleep isn't just for humans! Every animal with a complex brain needs it, and they all show these slow brain waves during deep sleep. Evolution has preserved this feature for a reason—it's essential for brain health and function! #ComparativeNeuroscience

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 08/05/2025

Fascinating brain fact: Neurons in your thalamus (deep in your brain) and cortex (outer layer) talk to each other during sleep, creating different rhythms. This "thalamocortical dialogue" orchestrates your sleep cycles and helps process memories. #NeuroscientistLife

Just like ocean waves, slow waves in your sleeping brain actually travel! They typically start in frontal regions and move toward the back of your brain. Each person has their own unique pattern of wave origin and direction. #NeuralWaves

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 07/05/2025

Ever notice how a power nap can improve your memory? During deep sleep, your brain replays neural activity patterns from your day, strengthening important connections and weakening less useful ones. It's like your brain's natural memory optimization! #BrainFacts #EEG

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 06/05/2025

Brain fact: Your cortex alternates between "Up states" (neurons active and firing) and "Down states" (neurons quiet) during deep sleep. This slow rhythm is like your brain's nighttime heartbeat, occurring about once per second. #NeuroscienceFacts

000

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 06/05/2025

Your brain cycles through different states during sleep: N1 (drowsy), N2 (light sleep), N3 (deep sleep), and REM. Each has a unique electrical signature that scientists can see on an EEG. Brain waves get progressively slower as you enter deeper sleep! #SleepCycles

000

Flavio Frohlich PhD @flaviofrohlich.bsky.social · 05/05/2025

Did you know your brain produces slow waves (<4 Hz) during deep sleep? These aren't just random noise—they're crucial for memory consolidation and allowing your brain to properly "file away" what you learned during the day! #Neuroscience #SleepScience

The most powerful self-improvement hack isn't in a book or behind a paywall—it's making eye contact with the barista, remembering your neighbor's kid's name, and putting your phone down when someone speaks. Changed my life when I realized genuine presence charges my batteries. #RealConnection
