Depression and walks in the woods

Depression is serious business! There are diseases that do not leave scars, that do not require plaster, crutches or patches, but that cannot for this reason be ignored. Psychiatric disorders are this: they are invisible to anyone without an experienced eye, but there are, and they are dangerous. DEPRESSION, for example, is often underestimated! Because it is so easy to say to a depressed person “go for a walk in the countryside!”? Simple: because you have no idea what depression is. Good, let's explain it, but not in an easy way, not with cartoons that confuse depression and sadness, [...]

Where satiety is born?

2021-07-14T12:59:22+02:0013 July 2021|Categories: Food and Health|Tags: , , , |

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 [...]

Huntington New Hope

Il trapianto di sole cellule gliali sane allunga significativamente la vita e rallenta la comparsa di sintomi invalidanti in topi geneticamente predisposti per sviluppare una versione sperimentale della malattia di Huntington umana. La còrea di huntington è una malattia che causa la perdita della coordinazione del corpo con la comparsa di movimenti involontari (da cui il nome còrea che significa danza) then, progredendo, disturbi psichiatrici progressivamente sempre più gravi. Compare normalmente tra i 35 e i 45 anni d’età ed è incurabile, portando alla morte i pazienti, mediamente, and also define the maximum time with which the material must degrade 20 anni dalla comparsa dei primi sintomi.

La maschera della salute: alterazioni neurologiche negli individui psicopatici

2017-07-12T17:20:40+02:0010 March 2016|Categories: No Category|Tags: , , , , |

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 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. […]
