  2. 1. Exploring Diversity in the Midbrain Dopamine System with Emphasis on the Ventral Tegmental Area

    Author : Bianca Vlcek; Åsa Mackenzie; Eva Hedlund; Uppsala universitet; []
    Keywords : ;

    Abstract : Midbrain dopamine neurons of the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) are important for motor, cognitive and limbic functions through substantial projections to forebrain structures. Dysfunction of the midbrain dopamine system is associated with several disorders, including Parkinson´s disease (PD) and substance use disorder. READ MORE

  4. 2. United in Diversity : A Physiological and Molecular Characterization of Subpopulations in the Basal Ganglia Circuitry

    Author : Thomas Viereckel; Åsa Wallén-Mackenzie; Åsa Konradsson-Geuken; Erika Comasco; Per Svenningsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glutamate; Optogenetics; Amperometry; Histology; Midbrain; Subthalamic Nucleus; Parkinson s disease; Ventral Tegmental Area; Substantia Nigra; Co-release;

    Abstract : The Basal Ganglia consist of a number of different nuclei that form a diverse circuitry of GABAergic, dopaminergic and glutamatergic neurons. This complex network is further organized in subcircuits that govern limbic and motor functions in humans and other vertebrates. READ MORE

  5. 3. Evolution of acetylcholine receptors and study of the anatomy of the mouse brain reward system

    Abstract : This thesis work is divided in two parts. In the first part, I make use of the transgenic TRPV1-Cre mouse line as a tool to investigate the midbrain ventral tegmental area (VTA). READ MORE

  6. 4. Across Borders : A Histological and Physiological Study of the Subthalamic Nucleus in Reward and Movement

    Author : Nadine Schweizer; Åsa Wallén-Mackenzie; Dai Stephens; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subthalamic nucleus; STN; basal ganglia; locomotion; hyperlocomotion; rearing; ventral tegmental area; VTA; dopamine; glutamate; vesicular glutamate transporter 2; Vglut2; Parkinson s disease; deep brain stimulation; subpopulation; conditional knock-out; optogenetic; co-expression; in situ hybridization; self-administration; reward behavior; mouse genetics;

    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

  7. 5. Motion and Emotion : Functional In Vivo Analyses of the Mouse Basal Ganglia

    Author : Emma Arvidsson; Åsa Wallén-Mackenzie; Cecilia Flores; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dopamine; Basal Ganglia; Reward System; In Vivo Chronoamperometry; Optogenetics; Deep Brain Stimulation; Parkinson’s Disease; Addiction; Glutamate; Vesicular Glutamate Transporter; VGLUT2; Sex; Age; Subthalamic Nucleus; Striatum; Nucleus Accumbens; Ventral Tegmental Area;

    Abstract : A major challenge in the field of neuroscience is to link behavior with specific neuronal circuitries and cellular events. One way of facing this challenge is to identify unique cellular markers and thus have the ability to, through various mouse genetics tools, mimic, manipulate and control various aspects of neuronal activity to decipher their correlation to behavior.
