11. Across Borders : A Histological and Physiological Study of the Subthalamic Nucleus in Reward and Movement
Abstract : The basal ganglia are the key circuitry controlling movement and reward behavior. Both locomotion and reward-related behavior are also modified by dopaminergic input from the substantia nigra and the ventral tegmental area (VTA). READ MORE

12. On the Causal Mechanisms of Stuttering
Abstract : Stuttering is one of the most common speech disorders. However, the etiology is poorly understood, and is likely to be heterogeneous. The aim of this thesis was to clarify causal mechanisms, focusing the brain. READ MORE

13. Structure-Dynamics relationship in basalganglia: Implications for brain function
Abstract : In this thesis, I have used a combination of computational models such as mean field and spikingnetwork simulations to study various sub-circuits of basal ganglia. I first studied the striatum(chapter 2), which is the input nucleus of basal ganglia. READ MORE

14. The subthalamic nucleus in motor and affective functions : An optogenetic in vivo-investigation
Abstract : The basal ganglia form a group of subcortical interconnected nuclei involved in motor, limbic and cognitive functions. According to the classical model of the basal ganglia, two main pathways exert opposing control over movement, one facilitating movement and the other suppressing movement. READ MORE

15. Characterisation of inputs and outputs of striatal medium spiny neurons in health and disease
Abstract : 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.
