C'ERA UNA VOLTA UN NEURONE... STORIA DI UN GROVIGLIO CHIAMATO CERVELLO.
Venerdì 17 marzo
Partenza ore 20:00 - 21:00 - 22:00 (ultima corsa riservata agli under 30)
Con Federico Luzzati, NICO - Neuroscience Institute Cavalieri Ottolenghi e Dipartimento Scienze della Vita e Biologia dei Sistemi Università di Torino e Ilaria Stoppa, Associazione CentroScienza Onlus.
Gli organismi animali, come le meduse, i pesci, i bradipi o gli esseri umani, sono quasi tutti dotati di alcune cellule speciali: i neuroni. Queste cellule amano comunicare: sono connesse tra loro e si sono specializzate nel trasmettere ed elaborare gli stimoli interni ed esterni. Dalla loro comparsa, circa 600 milioni di anni fa, i neuroni sono diventati sempre più numerosi e in alcune specie hanno iniziato a raggrupparsi in intricatissimi grovigli di connessioni capaci di eseguire compiti sempre più complessi. Correre, saltare, percepire gli odori, o elaborare un'idea o un progetto: tutto passa attraverso l'intricata rete di neuroni che chiamiamo cervello. Ma come funziona un neurone? Scopriamolo viaggiando a bordo del tram della scienza tra esperimenti e inganni per mettere alla prova il nostro cervello!
This neuron, created in the Su-Chun Zhang lab at the University of Wisconsin-Madison, makes dopamine, a neurotransmitter involved in normal movement. The cell originated in an induced pluripotent stem cell, which derive from adult tissues. Similar neurons survived and integrated normally after transplant into monkey brains -- as a proof of principle that personalized medicine may one day treat Parkinson's disease.

Inside every adolescent brain, 86 billion neurons connect and collide to produce the most frustrating, chaotic and exhilarating changes that will ever happen to us.
#LYTMindYourHead
Lyceum Youth Theatre and Traverse Young Writers present Mind Your Head, a double bill of performances which examines the hot topic of mental wellbeing for young people today.
Each evening show will feature Brainstorm, exploring the complexities of the adolescent brain in a unique performance conceived by a playwright, a neuroscientist and partially devised by the LYT cast themselves.
Brainstorm will be paired with a selection of short scenes by the Traverse Young Writers who have responded to themes of the science and biology behind emotions, and nature verses nurture
What does happiness mean? Is it material or emotional? Controlled by circumstances or temperament?

I had a 7:00am sound check this morning. That whole concept is so wrong. Musicians aren't wired for mornings to start with, so asking us to do something at 7:00am is silly.
Asking us to do make music at 7:00am is sillier still.
7:00am Sound check? It's an oxymoron, like Airborne Infantry, and Military Intelligence.
So, this is an MRI printout I had done this morning after sound check, teaching, major's market, dot dot dot. This is my brain, not wired for mornings.
Neurona AP de sanguijuela (Hirudo medicinalis) regenerando en medio de cultivo con Concanavalina A... Ok después del choro técnico, esto era lo que hacia en el Instituto de FisiologÃa Celular, antes de cambiar los microscópios por los binoculares, o sea, antes de ser biólogo de campo era una rata de laboratorio que es lo mismo que un Biólogo molecular o BiofÃsico =) ja ja.. Sin ofender, que tengo muchos amigos biólogos moleculares
Neurons transmit electrical signals to muscles through a thin connection called an axon. The axon is covered by a sort of insulation called the myelin sheath, which is like the plastic coating on your charger cord. In ALS, this coating is eaten away, and the signal is lost before it reaches the muscle. When the muscle stops recieving signals, it begins wasting away. Using a copper-rich compound, OSU professor Joe Beckman and his team were able to restore the myelin sheath in mice damaged by ALS. The compound is in clinical trials to evaluate its safety, and patients and their families are cautiously optimistic that this might help extend the lives of people with Lou Gehrig’s disease. #OSU150
Neurone du cervelet (structure triangulaire en rouge au centre ; son noyau, circulaire apparaît en violet) projetant ses prolongements vers le site de genèse des mouvements involontaires dans la maladie de Parkinson. La stimulation intermittente des terminaisons nerveuses (en vert) dans un modèle de Parkinson chez la souris permet de prévenir l’apparition de ces mouvements involontaires.

En savoir plus : Dans une étude parue en juin 2022, des chercheurs et chercheuses sous la supervision de Clément Léna et Daniela Popa, directeur et directrice de recherche Inserm, montrent que des stimulations depuis la surface du cerveau, au niveau du cervelet, suffisent à supprimer les mouvements involontaires (ou dyskinésies) liés à la maladie de Parkinson.
Ils ont entrepris de tester une voie thérapeutique alternative pour traiter ces mouvements anormaux dans un modèle animal de la maladie de Parkinson. Ils ont administré des stimulations spécifiques des cellules de Purkinje du cervelet depuis la surface du cerveau, quelques dizaines de secondes par jour.
Celles-ci se sont révélées capables de supprimer les mouvements anormaux. Mieux encore, ce traitement a normalisé l’activité des circuits moteurs, y compris au niveau du site de genèse présumée de ces dyskinésies, au sein des ganglions de la base.
Les résultats ont montré que ce traitement met en jeu des mécanismes de plasticité, qui perdurent pendant plusieurs jours voire semaines. Ces stimulations de la surface du cervelet, administrables de façon non invasive, fournissent une voie d’accès nouvelle pour le traitement d’affections profondes dans le cerveau. Les mécanismes cellulaires des plasticités restent à être identifiés.
L’équipe cherche maintenant à mieux comprendre et à optimiser ces pratiques pour reproduire leurs effets bénéfiques chez les patients
