  2. 1. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

    Author : Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

    Abstract : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

  4. 2. GABA in the islets of Langerhans

    Author : Anna Wendt; Diabetes - öcellsexocytos; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetologi; sekretion; Endokrinologi; Endocrinology; SLMV; paracrine regulation; LDCV; islets of Langerhans; autocrine regulation; GABA; diabetology;

    Abstract : GABA (γ-aminobutyric acid) is a well-known inhibitory neurotransmitter in the CNS. GABA is also present at high concentrations in the insulin-producing β-cells in the islets of Langerhans, but its function there is less clear. GABA is believed to accumulate in SLMVs (synaptic-like microvesicles). READ MORE

  5. 3. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

    Author : Marie Anzelius; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

    Abstract : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. READ MORE

  6. 4. Physiology and Pharmacology of GABAA receptors: The Brakes in the Brain

    Author : Catarina Lindquist; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Fysiologi; Ion channels; GABA; Inhibition;

    Abstract : 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). READ MORE

  7. 5. GABA-, glycine- and glutamate-induced currents in rat medial preoptic neurons : functional interactions and modulation by capsaicin

    Author : Urban Karlsson; Staffan Johansson; Johannes Krupp; Bryndis Birnir; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic transmission; glutamate; GABA; glycine; TRPV1; Physiology; Fysiologi;

    Abstract : The medial preoptic nucleus (MPN) of the hypothalamus plays a major role in many functions involved in maintaining bodily homeostasis, such as thermoregulation and osmoregulation, as well as in the control of complex behaviours, e.g. sexual behaviour. READ MORE
