2. The hippocampal opioid system : role in spatial learning
Abstract : The main aim of the present thesis was to study the role of the endogenous hippocampal opioid system, and in particular, the role of dynorphin B and nociceptin, in spatial learning. The effects of bilateral infusion (using chronic cannulae) of dynorphin B into the dorsal hippocampus (CA3-region), an area containing a high number of dynorphin-containing neurons, were examined in the Morris swim-maze, a spatial task dependent on hippocampal functioning.

This cholinergic system is strongly impaired in Alzheimer's disease and in age-related dementias. READ MORE
