1. Modeling Biochemical Network Involved in Striatal Dopamine Signaling
Sammanfattning : 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).

2. Modeling receptor induced signaling in MSNs : Interaction between molecules involved in striatal synaptic plasticity
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
3. Pharmacological and genetic manipulation of adipose cell differentiation and metabolism
Sammanfattning : Adipose tissue dysfunction has a pivotal role in the development of obesity and related metabolic complications, such as insulin resistance, cardiovascular disease, and diabetes. The overall aim was to study the consequences of adipose exposure to pharmacological agents, as well as dysregulations in the expression of genes, potentially involved in adipose tissue dysfunction and related metabolic impairments.

4. Selectivity of dopamine D1 and D2 receptor agonists – A combined computational approach
Sammanfattning : Dopamine (DA) is an endogenous neurotransmitter acting in the central nervous system. DA plays a key role in many vital brain functions such as behavior, cognition, motor activity, learning, and reward. Dopamine receptors belong to the rhodopsin like family of G-protein coupled receptors (GPCRs). LÄS MER
5. Dopamine and the affective-cognitive gradient in the human striatum studied with multimodal brain imaging
Sammanfattning : Both dopamine and the dopamine rich brain area, striatum, have been linked to behaviors related to incentives, motor action, and associative processing. Most of the cortex sends projections to the striatum, these connections have been described as a gradient organization representing a repertoire of functional behaviors. LÄS MER
