Riassunto
Che il sonno faccia bene lo sanno tutti. Pochi però sono a conoscenza che durante questo processo fisiologico e caratteristico di tutte le specie viventi si consolidano, o più semplicemente si memorizzano, le informazione acquisite durante la veglia. Quando apprendiamo una nuova nozione, come può essere quella di eseguire in maniera diversa un movimento, è necessario che l’informazione acquisita venga immagazzinata, elaborata e consolidata al fine di poterla utilizzare quando se ne presentino le condizioni [1]. Il nostro cervello ha destinato precise aree al consolidamento mnesico e da pochi anni sappiamo che in questi luoghi cerebrali, anche durante il sonno, continuano a svolgersi tali processi e sarebbe proprio quest’ultimo il fattore determinante per memorizzare più rapidamente il »come si eseguono le azioni«. Tali evidenze hanno incuriosito moltissimi neuroscienziati, tra cui, inevitabilmente, coloro che si occupano di migliorare le prestazioni motorie in ambito sia sportivo sia riabilitativo. Però, se da un lato la ricerca neuroscientifica ha svelato molti dei segreti chimici e molecolari alla base del consolidamento mnesico, dall’altro ancora pochi sono gli studi che si prefiggono di correlare il sonno a tali fenomeni neurobiologici. Prima di approfondire tali argomenti è necessario analizzare i meccanismi neuronali sottostanti il consolidamento mnesico, nonché cos’è il sonno e cosa significhi, da un punto di vista di attività cerebrale, il dormire.
