Children who take music lessons develop a larger corpus callosum, the bridge between the two halves of the brain, and the change is permanent. A 2005 review in the Annals of the New York Academy of Sciences found that early music training produces structural brain changes that persist into adulthood, even if the person stops playing.
The review was led by Gottfried Schlaug at Harvard Medical School, one of the leading researchers on music and the brain. He found that children who started instrumental training before age seven had a significantly larger anterior corpus callosum than non-musicians, and the size difference was still visible in adults who had not touched an instrument in years.
The corpus callosum carries signals between the left and right hemispheres. A larger one means faster, richer communication between the two sides, and the effect shows up in tasks that have nothing to do with music: spatial reasoning, verbal memory, and the ability to process multiple streams of information at once. The music built the highway, and the brain uses it for everything.
Schlaug also found that musicians had larger cerebellums, the region involved in timing and motor coordination, and more grey matter in the areas that process sound. The brain had physically reorganised itself around the demands of the instrument, and the reorganisation was visible on a scan.
The age window matters. Children who started before seven showed the largest changes. Children who started after ten showed smaller ones. Adults who took up an instrument for the first time showed the least structural change, though they still showed some. The brain is most willing to be rebuilt by music during the years when most parents are debating whether to sign their child up for lessons. https://t.co/hrHlmtHjjg
Can you please clarify why a nurse was allowed to suture such an extensive and contaminated wound?
It should’ve been done by a doctor.
The response from the nursing director is shameful.
This guy has got a bad scar and could’ve ended up with necrotising fasciitis.
Please investigate this properly.
@JohnSmithwfhnu@CwmTafMorgannwg@NHSWales_PI Absolutely dangerous. This patient should’ve been reviewed by a proper surgeon to close the wound in layers.
If the nurse practitioner does not know how to put in deep sutures, why did they have a crack?
Next September, 2027 at this exact time, you will be standing in the places you used to dream about. Living your most beautiful rich life. Send this to yourself.
Some of my absolute vocal bests are coming up and I’m SO excited. And I rarely get excited lol, so you know that this means a lot. love that I get to keep challenging my voice and discovering what else I can do with it. grateful 🩶
In a newborn ward at a Delhi hospital in 1985, babies were falling sick with severe diarrhoea.
A doctor noticed something the outbreak was doing that nobody expected.
The babies who caught it first were not getting seriously ill again.
His name was Doctor Maharaj Kishan Bhan.
He was a paediatrician at the All India Institute of Medical Sciences in New Delhi. Rotavirus, the virus behind that outbreak, is the leading cause of severe diarrhoea in small children, and it kills a very large number of them every year, mostly in poor countries.
During that outbreak he isolated the particular strain of rotavirus infecting those newborns. It was labelled 116E.
Then he made the connection that mattered. If a natural infection with this Indian strain was protecting these babies from later severe illness, then this strain could be turned into a vaccine.
That idea took about 3 decades to become a product.
He carried it the whole way. He later became Secretary of India's Department of Biotechnology, which gave him something rarer than a laboratory. It gave him the ability to make a government, an industry and international partners work on the same problem at the same time.
The vaccine that came out of it is called Rotavac, manufactured by an Indian company in Hyderabad.
It became the first Indian rotavirus vaccine to be pre qualified by the World Health Organisation, which is what allows a vaccine to be bought and used by other countries.
It went into India's national immunisation programme, which means the families who need it most receive it free.
The strain inside it came from Indian babies in an Indian hospital ward in 1985.
He died in 2020.
Most vaccines used in poor countries are developed elsewhere, for populations elsewhere, and then adapted. This one was found in the children it was meant to protect.
I still think about the guy who pointed out that "the underlying purpose of Al is to allow wealth to access skill while removing from the skilled the ability to access wealth." Rarely have I seen Al described so succinctly.
🇳🇴🧊 ÉLECTROCARDIOGRAMME PLAT PENDANT 2 H 35. LE MÉDECIN A REFUSÉ DE LA DÉCLARER MORTE.
Trois internes de l'hôpital de Narvik, dans le nord de la Norvège, descendent un couloir enneigé après leur garde.
L'une d'elles perd le contrôle.
Elle part la tête la première et traverse la glace d'un ruisseau gelé, en contrebas d'une cascade. Elle finit sur le dos, la tête et le torse dans l'eau, sous vingt centimètres de glace.
Ses deux collègues l'attrapent par les skis. Ils tiennent.
Le souci ?
Ils n'arrivent pas à la sortir. La glace ne cède pas.
Sauf que.
Il y a une poche d'air coincée sous la surface. Elle respire dedans.
Quarante minutes.
Puis elle s'arrête.
Un ouvrier finit par arriver avec une pelle de jardin pointue. La glace cède.
Elle est sous l'eau depuis 80 minutes.
Pas de pouls. Pas de respiration. Pupilles dilatées.
Température corporelle : 13,7 °C.
Une heure d'hélicoptère jusqu'au CHU de Tromsø. À l'arrivée, l'ECG est une ligne droite. Le chef du service d'urgence dira : on aurait pu la tracer à la règle.
Il applique alors la règle des médecins du Grand Nord.
« Nous ne la déclarerons pas morte tant qu'elle ne sera pas chaude et morte. »
Plus de cent soignants se relaient neuf heures. Le sang est extrait du corps, réchauffé par une machine de circulation extracorporelle, réinjecté. Degré par degré.
Le cœur repart.
Arrêt circulatoire total : 2 heures et 35 minutes.
Elle se réveille dix jours plus tard, paralysée du cou aux pieds. Deux mois de réanimation. Des mois de rééducation.
Aujourd'hui :
• Elle marche
• Il lui reste de légères séquelles nerveuses aux mains et aux pieds
• Elle est médecin au CHU de Tromsø, l'hôpital qui l'a ranimée
Anna Bågenholm, 29 ans à l'époque, chirurgienne en formation. Elle détient la plus basse température corporelle jamais survécue en hypothermie accidentelle.
Son cas a réécrit les protocoles d'urgence dans le monde entier.
Personne n'est mort tant qu'il n'est pas chaud et mort.
(Anna Bågenholm, montagnes de Narvik, Norvège, 20 mai 1999 ; réanimation dirigée par le Pr Mads Gilbert, CHU de Tromsø ; cas publié dans The Lancet, 2000)
