1. 1. Differences in glutamatergic transmission onto interneurons and pyramidal cells in the rat hippocampus

   Författare :Ilse Riebe; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AMPA; development; glutamate transmission; hippocampus; interneuron; NMDA; synapse;

   Sammanfattning : In the human brain there are about 100 billion excitatory glutamatergic neurons and 10 billion inhibitory GABAergic neurons. During development, these neurons are synaptically wired together into neural networks, functionally prepared to perform the full register of brain functions, and to learn from experiences. LÄS MER

3. 2. Neuronal Development in the Embryonic Retina : Focus on the Characterization, Generation and Development of Horizontal Cell Subtypes

   Författare :Per-Henrik Edqvist; Finn Hallböök; Steven McLoon; Uppsala universitet; []
   Nyckelord :Neurosciences; Activin; Chick; Follistatin; Interneuron; Isl1; Lim1; Migration; Neurogenesis; Prox1; Transcription factor; Neurovetenskap;

   Sammanfattning : Horizontal cells are retinal interneurons that modulate the output from photoreceptors. Two horizontal cell (HC) subtypes are commonly identified in the vertebrate retina: axon-bearing and axon-less HCs. LÄS MER

4. 3. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models

   Sammanfattning : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. LÄS MER

5. 4. On the Mechanisms Behind Hippocampal Theta Oscillations : The role of OLMα2 interneurons

   Författare :Sanja Mikulovic; Richardson Leao; Klas Kullander; Stefan Remy; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; interneuron; optogenetics; theta oscillations; anxiety;

   Sammanfattning : Theta activity is one of the most prominent rhythms in the brain and appears to be conserved among mammals.  These 4-12 Hz oscillations have been predominantly studied in the dorsal hippocampus where they are correlated with a broad range of voluntary and exploratory behaviors.

7. 5. On GABAergic interneuron diversity and maturation

   Författare :Hermany Munguba; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : GABAergic interneurons provide finely, distinct styles of inhibition granted by their unique targeting preferences, molecular profiles, and morphological silhouettes. A central quest of my thesis was to explore what constitutes such diversity, touching upon how this di- versity is reached and preserved during development and what maintains distinct functional features later on.
