L'olfatto è il più primordiale dei cinque sensi e suscita profonde emozioni, per esempio passione o disgusto, ma il modo in cui esercita la sua influenza sul cervello resta, in gran parte, un mistero.
La ricerca inizia a far luce su questi meccanismi, scoprendo che la tensione influenza l'elaborazione olfattiva, trasformando odori buoni in cattivi.
