Jari Tiihonens forskargrupp

Psykofarmakologi, schizofreni och drogmissbruk

Jari Tiihonens huvudsakliga forskning inom psykiatrin fokuserar på psykofarmakologiska studier; exempelvis vad gäller risken för självmord för personer som använder antidepressiva eller antipsykotiska läkemedel jämfört med personer som inte gör det. Med teknik som functional brain imaging och autoradiografi studerar han även signalsubstanserna dopamin och serotonin och deras receptorer i hjärnan samt epidemiologiska, genetiska och neurobiologiska mekanismer bakom drogberoende och våldsamt beteende.
