3. 37. Serotonergic receptor subtypes in learning and memory : focus on 5-HT1A, 5-HT1B and 5-HT2A receptors

   Författare :Maria Lüttgen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Serotonin; 5-HT1A receptor; 5-HT1B receptor; 5-HT2A receptor; acetylcholine; NMDA receptor; water maze; passive avoidance; septum; hippocampus; teaming; memory; immunohistochemistry; mRNA;

   Sammanfattning : The aim of this thesis was to study how serotonin (5-HT) receptor subtypes can influence hippocampus/amygdala-dependent teaming and memory using the water maze (WM) and the passive avoidance (PA) tasks in rodents, and to provide a cellular correlate to the behavioral results using histochemical methods. Glutamatergic neurons in the trisynaptic circuit of the hippocampus are believed to be important for spatial teaming and memory as well as synaptic plasticity. LÄS MER

   Sammanfattning : Taking child poverty into account as an enormous concern on the pathway to human development, the present dissertation aims to examine child poverty’s extent and characteristics, poor children’s views on this issue and their policy recommendation to reduce it. The research questions are: 1) what are the extent and characteristics of child poverty in Bangladesh? 2) What is child poverty? Why and how do children experience it? 3 (a) To what extent and in what respect does child poverty differ between Bangladesh and China? 3 (b) What are the reasons for the differences in child poverty over time between the two countries? 4 ) What is needed to reduce child poverty in Bangladesh according to its principal victims? The present dissertation is based on research mainly with young children aged up to 14 years. LÄS MER
