16. The γ-aminobutyric acid and proton signaling systems in the zebrafish brain : Characterization and effect of stress
Sammanfattning : The central nervous system of vertebrates is continuously processing sensory information relayed from the periphery, integrating it and producing outputs transmitted to efferents. In the brain, neurons employ an array of messenger molecules to filter afferent information and finely regulate synaptic transmission. LÄS MER
17. Conditional and non-conditional reward-related responses to alcohol. Nicotinic mechanisms
Sammanfattning : The mesolimbic dopamine system is believed to mediate the positive reinforcing and rewarding effects of addictive drugs by increasing dopamine levels in its terminal area, the nucleus accumbens (nAc). Nicotinic acetylcholine receptors (nAChRs) within this system appear important for the pharmacological actions of both alcohol and nicotine, which may explain the frequent co-abuse of these two drugs.

18. Physiology and Pharmacology of GABAA receptors: The Brakes in the Brain
Sammanfattning : Inhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). LÄS MER
19. Expression and function of thyroid hormone receptor alpha 1 in the brain
Sammanfattning : Thyroid hormone is fundamentally important for development and maintenance of adult brain functions and maternal hypothyroxinemia during pregnancy can lead to a severe mental retardation known as endemic cretinism. The first realization that endemic cretinism is caused by iodine deficiency and its association with thyroid hormone was made a century ago; this eventually resulted in dietary supplementation programme, e.

20. Pharmacophore Refinement and Lead Optimization - A study of the benzodiazepine site of the GABAA receptors
Sammanfattning : Structure activity relationship studies of synthetic flavone derivatives have been utilized to refine and evaluate a pharmacophore model of the benzodiazepine binding site of the GABAA receptors, originally developed by Zhang et al. (Drug Des. Discovery 1995, 12, 193-248). LÄS MER
