  1. 1. Characterisation of inputs and outputs of striatal medium spiny neurons in health and disease

    Författare :Marko Filipović; Jeanette Hellgren Kotaleski; Arvind Kumar; Gilad Silberberg; Ad Aertsen; Andrew Sharott; KTH; []

    Sammanfattning : Striatal medium spiny neurons (MSNs) play a crucial role in various motor and cognitive functions. They are separated into those belonging to the direct pathway (dMSNs) and the indirect pathway (iMSNs) of the basal ganglia, depending on whether they express D1 or D2 type dopamine receptors, respectively.

  3. 2. Targeting and driving somatosensory neurons

    Författare :Fabio Freitag; Malin C. Lagerström; Andrew Todd; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain; Itch; GRPR interneurons; dorsal horn; trigeminal nucleus caudalis; Barrel field;

    Sammanfattning : Pain and itch are two distinct sensations, but the fundamental question of how our nervous system distinguishes the processing and encoding of their related information is still far to be clearly delineated. At the spinal cord level, evidences have pointed out specific groups of neurons expressing the gastrin releasing peptide (Grp) and its receptor (Grpr) as responsible for carrying specifically itch-related information.

  4. 3. Exploring the miRNA profile of medium spiny neurons using retrograde transport in rats

    Författare :Marcus Lockowandt; CNS Genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The basal ganglia play an essential role in movement selection and control. It is therefore not surprising that they are central to neurodegenerative diseases like Parkinson’s disease and Huntington’s disease. LÄS MER

  5. 4. Modeling receptor induced signaling in MSNs : Interaction between molecules involved in striatal synaptic plasticity

    Författare :Anu G. Nair; Jeanette Hellgren Kotaleski; Omar Gutierrez-Arenas; Upinder S. Bhalla; Pierre Vincent; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Striatal synaptic plasticity; LTP; Dopamine; Acetylcholine; Synergy; Medium spiny neurons; MSNs;

    Sammanfattning : 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. LÄS MER

  7. 5. Untangling Cortico-Striatal Circuitry and its Role in Health and Disease - A computational investigation

    Författare :Jovana Belic; Jeanette Hellgren Kotaleski; Arvind Kumar; Abigail Morrison; Arthur Leblois; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cortico-striatal circuits; levodopa-induced dyskinesia; Parkinson’s disease; effective connectivity; cross-frequency coupling; corticostriatal network; network oscillations; GABAergic transmission. basal ganglia; striatum; cortex; fast spiking interneurons; medium spiny neurons; neuronal avalanches;

    Sammanfattning : The basal ganglia (BG) play a critical role in a variety of regular motor and cognitive functions. Many brain diseases, such as Parkinson’s diseases, Huntington’s disease and dyskinesia, are directly related to malfunctions of the BG nuclei. LÄS MER
