Type of Research Project
- Basic science
What is the background of the project?
Synaptic transmission is the key cellular process that determines neuronal communication and basically all brain functions. Any alteration in synaptic transmission leads to disease, including Amiotrophyc Lateral Sclerosis (ALS), Spinal muscular atrophy (AMS) or neurodegenerative disorders like Alzheimer or Parkinson disease. The quantification of synaptic vesicles in neurons is of fundamental importance to know when disease will appear. In our lab we use hippocampal neurons in culture and measure neuronal activity with genetically encoded fluorescence proteins in an inverted microscope. We also use mice carrying different mutation of proteins involved in synaptic transmission.
What is the aim of the project?
To quantify the number of synaptic vesicles pools that are mobilized during brain activity
What techniques and methods are used?
Neuronal primary cultures Electrophysiology Image processing and analysis Genetically encoded fluorescence proteins
