Where satiety is born?

The sense of satiety induces man not to eat continuously and puts a brake on his need, often excessive, of food. Hunger and satiety affect everyone's eating behavior, but what exactly do they depend on? Satiety is a signal triggered by the brain when it receives too much sugar. In fact, after a meal, when glucose levels momentarily rise, the signal reaches our brain, more precisely to astrocytes, the cells needed to support neurons. The astrocytes, at this point, they change shape and retract by activating some specific neurons of the hypothalamus, a structure of the central nervous system located in the [...]

From birds to bats: new animal models for the genetics of language

Human language is still today one of the most complex aspects of cognition to study and understand. What are the biological bases that allow a child to acquire at least one language only by being exposed to it? When did this ability emerge in the human species? Which genes and molecular processes are involved? How the competence of a language is implemented at the neural level? These are some of the questions that linguists have, psychologists, biology, paleoanthropologists and neuroscientists have been asking themselves for at least half a century [1]. In the second half of the 90s in some members of a British family, the so-called "KE family", è stata identificata una [...]

La maschera della salute: alterazioni neurologiche negli individui psicopatici

Cos’è uno psicopatico? Sebbene Hollywood e numerosi romanzi abbiano contribuito a creare un’immagine di tali individui familiare al grande pubblico, la risposta a questa domanda richiede conoscenze approfondite che si svincolino dalla percezione stereotipata dell’argomento. Lungi dall’essere un termine generico usato per indicare una qualunque malattia mentale, la psicopatia, spesso diagnosticata come disturbo antisociale di personalità, è infatti definita da molti esperti come un disordine connotato da peculiari manifestazioni patologiche. Nonostante esistano svariate scuole di pensiero, questi studiosi riferiscono come nello psicopatico siano infatti presenti tre precisi nuclei centrali che ne permettono l’identificazione: il deficit empatico, la cognitività ipertrofica e [...]

The effects of music on the brain

The world is full of great musicians suffering from pathologies that have not stopped them from becoming "i geni" undisputed in the history of music. Just think of Schumann and his "streak of madness" later classified as "schizophrenia", Beethoven and his early deafness, Mozart and the "Tourette Syndrome" which he was probably suffering from which causes tics, high-pitched sounds and loss of speech control, Petrucciani died in 1999 of "osteogenesis imperfecta" or "crystal bone syndrome" and Ezio Bosso suffering from "amyotrophic lateral sclerosis" or ALS, a neurodegenerative disease affecting motor neurons. Despite the serious [...]

The waves of the mind

Recent research has shown for the first time the possibility for neurons to influence each other at a distance by means of their weak electric field. This mode of transmission can occur both in a physiological way, in the propagation of theta waves of the REM phase, than in a pathological condition in the spread of epileptic seizures. […]

Sleeping to heal

A drug already approved and used to treat insomnia: lo Zolpidem, has been shown to facilitate healing after a stroke. The sleeping pill does not reduce the severity of the affected area, it helps her to heal, but it stimulates surrounding healthy tissues to reorganize to compensate for the functions performed by the damaged part of the brain.
