In Science, researchers report the observation of dendritic nanotubes in brain tissue from mice and humans. The discovery suggests that the current understanding of the brain’s organization may be incomplete, overlooking a hidden layer of connectivity. Learn more in a new

La gran importancia del eje intestino-cerebro 🧠 La microbiota intestinal modula el eje HPA (estrés ↔ cortisol) y con ello procesos clave como memoria, aprendizaje y emociones. 🔹Cuando hay disbiosis o estrés crónico, el eje se altera: aumenta la inflamación, se afecta la

Bello artículo sobre cómo los procesos cognitivos controlan el flujo de pensamientos. En este estudio, se demuestra que existe una diferencia entre el control inhibitorio motor y cognitivo. Queréis saber cuál es? Hilo va! 🧵

💤Redefiniendo el insomnio desde la neurociencia de sistemas. El insomnio no es solo un trastorno del sueño, sino una alteración en la regulación del estado de alerta, caracterizada por: 🔹 Hiperactividad en redes de salida y control ejecutivo 🔹 Mayor excitabilidad cortical y

Forget mind over matter. Neuroplasticity turns mind into matter. Your thoughts shape your brain.

This is how neurons form new connections in our brains By RogueMonkeyyt

Just out! “The astrocytic ensemble acts as a multiday trace to stabilize memory.” We identified astrocytic ensembles that link experiences across days to stabilize memory nature.com/articles/s4158…. New astrocyte tools are openly available at Addgene: addgene.org/Jun_Nagai/. 1/8

Astrocytes, Not Neurons, Hold the Key to Emotional Memory Astrocytes, the brain’s often-overlooked support cells, have been found to play a central role in stabilizing emotionally charged memories. After a powerful emotional event, these cells are biologically tagged with

How the brain talks to the immune system This diagram shows the inflammatory reflex - a neural circuit where the brain regulates inflammation through the vagus nerve. It’s how psychological stress, inflammation, and immune activity stay linked. 1️⃣ The signal starts in the brain

Engaging in creative, skill-based activities like dance, music, visual arts, or gaming can reduce your brain's biological age by ~6 years. Researchers measured the 'brain age gap' (the difference between predicted and actual brain age) and found that creative experts had

🧠📅 Hoy recordamos a Santiago Ramón y Cajal (1852–1934), padre de la neurociencia moderna. Demostró que el cerebro está formado por neuronas individuales, no por una red continua, y sentó las bases de la neuroanatomía. 🏅 Nobel de Medicina 1906 (junto a Golgi).

If there’s one thing I wish I had done differently when I was hit by a stroke last January, it would be to go to the hospital immediately, within the Golden Hour (<4.5 hours), instead of thinking I could just sleep it off. This “nothing will happen to me” attitude is common,

So happy to have received this news!! 😁

The presence of esophageal ducts in a mucosal biopsy is a clue that the sample was derived from the tubular esophagus.

Bile duct brushing: note the difference between the reactive ducts (left) and carcinoma (right).

A slide never lies. It only waits patiently for the right pathologist to read it.
