    Sammanfattning : The basal ganglia are evolutionary conserved nuclei located at the base of the forebrain. They are a central hub in the control of motion and their dysfunctions lead to a variety of movement related disorders, including Parkinson's disease (PD).The largest nucleus and main input stage of the basal ganglia is the striatum.

  3. 2. Neuronal assembly formation and non-random recurrent connectivity induced by homeostatic structural plasticity

    Författare :Julia Gallinaro; Pawel Herman; Alexander Kozlov; Stefan Rotter; Wulfram Gerstner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plasticity is usually classified into two distinct categories: Hebbian or homeostatic. Hebbian is driven by correlation in the activity of neurons, while homeostatic relies on a negative feedback signal to control neuronal activity. LÄS MER

    Sammanfattning : This thesis on Topological Combinatorics contains 7 papers. All of them but paper Bare published before.In paper A we prove that!i dim ˜Hi(Ind(G);Q) ! |Ind(G[D])| for any graph G andits independence complex Ind(G), under the condition that G\D is a forest. LÄS MER
