This relatively new group focuses on interdisciplinary research that incorporates the fields of Psychology, Neuroscience, and Immunology. The aim includes translational research, enabling basic laboratory findings to benefit societal health and wellbeing, in the area of neglected tropical diseases such as Bilharzia (Schistosomiasis), Sleeping Sickness (Trypanosomiasis), Malaria, and Hookworm infection. Research focus is on the involvement of cytokines, bacteria (Type1), and pathogens (Type2) in cognitive function.


Projects include:

  1. Effects of gene-deficiency (Loss of function approach) on cognitive function
  2. Immune and Neuronal cell interaction during learning and memory
  3. The influence of “stressors” and disease in learning and memory consolidation
