🚨 Forget “Dopamine = Pleasure” — Scientists just confirmed it does FAR more: Dopamine is the brain’s master learning signal that controls how we learn EVERYTHING! 🧠✨ (2026 update) The popular myth that dopamine is just the “pleasure chemical” is wildly oversimplified & outdated. Decades of research — highlighted in major 2025 reviews from the Howard Hughes Medical Institute’s Janelia Research Campus & related work in Neuron — show that dopamine primarily acts as a prediction error signal. It tells your brain the difference between what you expected & what actually happened, constantly updating your behavior, beliefs, decisions & skills. •When something is better than expected → dopamine bursts → “Great! Update your model & do more of this.” •When something is worse than expected → dopamine dips → “Not good. Change your approach.” This mechanism drives reward learning, but also language acquisition, motor skills, social cognition, decision-making & essentially all forms of learning throughout life. Why it matters: •Addiction: Floods the system with artificial “positive surprises,” trapping people in escalating cycles. •Parkinson’s: Loss of dopamine neurons impairs not just movement but learning flexibility. •Schizophrenia: Aberrant dopamine signaling may create false prediction errors, leading to delusions & hallucinations. Understanding dopamine as a learning optimizer (not just a feel-good molecule) is opening revolutionary new approaches to treating addiction, psychosis, learning disorders & more. •“Dopamine Is Not Pleasure — It’s a Prediction Error Signal” (clear breakdown of the science):
youtube.com/watch?v=dopamine… •“How Dopamine Controls Learning, Not Just Reward – Janelia Research Insights” •“The Real Role of Dopamine in the Brain: Beyond Pleasure” (2025–2026 neuroscience updates) The prediction error framework remains foundational, with ongoing refinements (including action prediction errors and circuit-specific teaching signals) expanding our understanding. This is established neuroscience with profound implications for mental health & learning. Drop a 🔥 if this changes how you think about dopamine!

Dopamine’s role as a prediction error / teaching signal is well-established across decades of research, with 2025 studies refining & expanding the model (e.g., action prediction errors, circuit-specific effects). The “pleasure only” view has long been debunked in scientific circles. This is for informational/educational purposes only — not medical advice.

🧠 How do you measure a thought? Use PubMed.ai to find out! A longstanding methodological problem in cognitive neuroscience is that value updating is typically inferred only under externally driven conditions. Most experimental paradigms rely on: • sensory stimuli • rewards or punishments • explicit feedback This implicitly treats the brain as a reactive system. A new Nature Communications study addresses a critical gap: direct measurement of endogenous value-related signals. 🔬 Study question How does the brain update preferences in the absence of external feedback? Using fMRI, the authors identified a value-like signal in the ventral striatum during pure internal simulation, with no sensory input or outcome delivery. The signal satisfies key properties of a prediction error, yet arises entirely from internally generated expectations. 🧠 Key finding The brain is capable of generating endogenous prediction errors, enabling value updating via a closed-loop internal model, rather than stimulus-driven reinforcement. This demonstrates that: - Value learning is not exclusively contingent on interaction with the external environment. 🧬 Methodological significance The highlighted ventral striatal activation (see image 👇) reflects: • imagination-driven valuation • internally computed discrepancy signals • learning without outcome feedback This provides experimental evidence that cognitive simulation alone can modify neural value representations. 📄 Nature Communications nature.com/articles/s41467-0… #Neuroscience #CognitiveNeuroscience #fMRI #VentralStriatum #PredictionError #ExperimentalDesign #MedEd #pubmedai

Claude makes you a false God Although I cannot do higher-dimensionally math without NumPy (which requires 64-bit pro version for integration with Amibroker, another 18k rupees from my standard version), I could create a simplified approximation of multiple linear regression using MACD, momentum and slope of past price movement with correlation-based weighting It has a 98% accuracy measured over 20 days (see highlight in left screenshot) for this sample stock. Blue line is predicted price plot, red dashed line is real price MAE = MA(abs(PredictionError), LookbackPeriod) // Average error over last 20 days AccuracyPct = 100 - (MAE / Close * 100) // Converts to percentage
