Om mig

John Axelsson och hans forskarteam på Karolinska Institutet vill med sin forskning öka kunskapen och medvetenheten om hur sömn och sjukdom i det moderna samhället påverkar vår biologi, kognition och hälsa. De frågor som John just nu är mest intresserad av att besvara är: Kan vår kropp och hjärna anpassa sig till långvarig sömnbrist? Kan mer sömn snabba upp återhämtning när vi är sjuka? Hur påverkar sjukdom vår hjärna och våra beteenden? Har människan ett varningssystem som gör att vi undviker personer som kan smitta oss och hur fungerar det? Hur snabbt vaknar hjärnan upp från sömn?
