1. Taste Hedonics and the Intake of Alcohol and Food
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
2. Ghrelin in feeding: new insights into its role and the neurocircuits involved
Sammanfattning : Appetite, originally evolved to ensure we consume enough of diverse nutrients to survive famines, has lost its survival advantage in our modern society, where food is plentiful. The hedonic aspect of appetite can indeed induce over-consumption of food, a major cause for the obesity pandemic. LÄS MER
3. Brain Stem Involvement in Immune and Aversive Challenge
Sammanfattning : Activation of the immune system by e.g. bacteria induces the acute-phase-response and sickness behaviour. The latter encompasses among other things fever, lethargy, anorexia and hyperalgesia. LÄS MER
4. Molecular mechanisms of nociception in the rat brain : anatomical connections and trans-synaptic regulation of gene expression of neurons in the pontine parabrachial nucleus
Sammanfattning : The pontine parabrachial nucleus (PB) is a major recipient of fibers fromnociceptive (pain-responsive) spinal and trigeminal dorsal horn neurons. With the use of combinations of molecular and morphological techniques, the anatomical connections of PB neurons and their expression of neuropeptide genes and transcription factors were studied, both in naive rats and in rats that had been subjected to nociceptive stimulation.

5. Structure and expression of the TP and EP1 prostanoid receptor genes
Sammanfattning : Prostanoids are ubiquitously distributed lipid signaling molecules derived from arachidonic acid, that exhibit numerous and diverse biological effects in a variety of physiological and pathophysiological conditions. The cell surface receptors for the prostanoids belong to the family of G protein-coupled receptors. LÄS MER
