  1. 1. Phenotypic Specification of Striatal Progenitors; Evidence for both cell-autonomous and environmental control as studied by transplantation into the adult and developing rodent brain

    Author : Martin Olsson; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; striatal projection neurons; striatal development; somatostatin; parvalbumin; neuronal differentiation; neural transplantation; medial ganglionic eminence; lateral ganglionic eminence; forebrain dvelopment; cholinergic; embryonic; thyroid transcription fa; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : The striatum is the major component of the ventral telencephalon and basal ganglia, involved in the processing of cortical information. The vast majority of the neuronal population in the striatum are striatal projection neurons, with connection to the globus pallidus and substantia nigra. READ MORE

    Abstract : Basal Ganglia are evolutionarily conserved brain nuclei involved in several physiologically important animal behaviors like motor control and reward learning. Striatum, which is the input nuclei of basal ganglia, integrates inputs from several neurons, like cortical and thalamic glutamatergic input and local GABAergic inputs. READ MORE

  3. 3. Striatal adenosine A2A receptors

    Author : Per Svenningsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; caffeine; adenosine; A2A receptors; dopamine receptors; striatum; basal ganglia; immediate early genes; c-fos; NGFI-A; DARPP-32; in situ hybridization;

    Abstract : The nucleoside adenosine exerts a modulatory action in the central nervous system by activating G-protein coupled receptors. Four such receptors are cloned and pharmacologically characterized: A1, A2A, A2B and A3. Caffeine, the most widely consumed psychostimulant, acts as an adenosine receptor antagonist predominantly on the first two. READ MORE

  4. 4. Striatal signaling in the treatment of Parkinson's disease

    Author : Irene Sebastianutto; Basala gangliernas patofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Parkinson’s disease (PD) is a neurodegenerative disorder characterized by typical motor symptoms that are caused by depletion of dopamine (DA) in the striatum. These symptoms are treated with the DA precursor L-DOPA, or with DA receptor (DAR) agonists. READ MORE

  5. 5. Modeling Biochemical Network Involved in Striatal Dopamine Signaling

    Author : Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez Arenas; Upinder Singh Bhalla; Jakob Kisbye Dreyer; KTH; []

    Abstract : In this thesis, I studied the molecular integration of reward-learning related neuromodulatory inputs by striatal medium-sized projection neurons (MSNs) using mass-action kinetic modeling.It is known that, in reward learning, an unexpected reward results in transient elevation in dopamine (peak) whereas omission of an expected reward leads to transient dopamine decrease (dip).
