1. 1. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

   Författare :Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

   Sammanfattning : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. LÄS MER

3. 2. Striatal pathways in dyskinesia and dystonia

   Författare :Laura Andreoli; Basala gangliernas patofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Striatum; Dystonia; L-DOPA-induced dyskinesia; DREADD; Mouse model; Dopamine; dopamine receptor;

   Sammanfattning : Purposeful and well-coordinated movements depend on the control exerted by dopamine (DA) on the basal ganglia (BG) network. Accordingly, dysfunctions or lesions of the dopaminergic system in the BG can result in an overall poverty and slowness of movement, cardinal features of Parkinson´s disease (PD), or in dyskinesias, exaggerated and involuntary movements resulting from L-DOPA pharmacotherapy.

4. 3. Brain glycine receptors as a common target for alcohol and the relapse-preventing drug acamprosate - a preclinical study

   Författare :Pei Pei Chau; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alcoholism; Acamprosate; Glycine receptor; Preclinical study; Dopamine; Ethanol;

   Sammanfattning : Alcohol abuse and dependence make up the most prevalent categories of substance use disorders in the world. Converging evidence from the current research group has identified two receptor populations, the glycine (GlyRs) and nicotinic acetylcholine receptors (nAChRs) in the mesolimbic dopamine system, as two potentially important targets for the development of new medication to treat alcohol dependence.

5. 4. Afferent input to midbrain dopamine neurones and its modulation : an electrophysiological study i vitro

   Författare :Pernilla Grillner; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :dopamine neurones; synaptic transmission; NMDA receptors; L-type Ca2 channels; presynaptic inhibition; metabotropic glutamate receptors; muscarine; nicotine;

   Sammanfattning : Dopamine (DA) neurones of the ventral mesencephalon are involved in the control of reward related behaviour, cognitive functions and motor performances, and provide a critical site of action for major categories of neuropsychiatric drugs, such as antipsychotic agents, dependence producing drugs and anti-Parkinson medication. The midbrain DA neurones are mainly located in the substantia nigra pars compacta (SNPC) and the ventral tegmental area (VTA). LÄS MER

7. 5. Multiple neurotransmitter inputs modulate circadian clock neurons in Drosophila

   Författare :Yasutaka Hamasaka; Dick Nässel; François Rouyer; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; circadian; Drosophila; neurotransmitter; G-protein coupled receptor; Neurobiology; Neurobiologi;

   Sammanfattning : Most animals have endogenous circadian clocks, which drive daily rhythms in behavior and physiology to adapt to daily cycles of the environment. Several sets of neurons have been identified as circadian pacemakers (clocks) in the brain of Drosophila melanogaster, but the neuronal circuits and neurotransmitters signalling circadian information are poorly known.
