Sammanfattning : This thesis includes four papers based on animal experimental work. They analyze the way in which activation of a specific motivational state - hunger- modulates the rewarding actions of alcohol and taste palatability. LÄS MER
Sammanfattning : 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.

Sammanfattning : The aim of the present thesis was to study how the neuropeptide galanin affects the neurochemistry and functional activity of the cholinergic septohippocampal projection, which plays a pivotal role in learning and memory. This cholinergic system is strongly impaired in Alzheimer's disease and in age-related dementias. LÄS MER
4. The prefrontal cortex and information processing : nitric oxide signaling studied in an animal model of schizophrenia
Sammanfattning : The prefrontal cortex has been extensively linked to several cognitive domains that are severely compromised in schizophrenia. It has therefore become a key region for studies on the disabling cognitive dysfunction commonly observed in patients with schizophrenia. LÄS MER
Sammanfattning : The immune system is essential for host defense against microbial pathogens and for wound healing processes. Inflammatory reactions, however, invariably cause tissue damage. LÄS MER
