Mechanisms Underlying Neuronal ActivityPosted by: National Institutes of Health (NIH)
Posted date: 2019-Apr-09
Projects focus on the mechanisms underlying neuronal activity using GnRH neurons in vitro and in vivo. In vivo, GnRH neurons, spread throughout the forebrain, release GnRH in a pulsatile fashion to control reproduction. In explants, primary GnRH neurons continue to release in a pulsatile fashion and show synchronized calcium oscillations. Projects utilize the GnRH system to study molecular and cellular properties of neuronal activity (individual cells and neuronal population dynamics) at different developmental, metabolic and/or reproductive states.Qualifications:
Candidate with experience in calcium imaging or electrophysiology and mouse anatomy preferred but not mandatory. Laboratory uses multidisciplinary approaches: cre/lox mice, transgenic lines, imaging, nasal explants, acute slices, videomicroscopy, calcium imaging, electrophysiology, immunocytochemistry, in situ histochemistry, single-cell PCR, and subtractive cDNA screening. Candidates should have training in one of the following: Electrophysiology, Neurobiology, Neuroendocrinology or Molecular biology.To Apply:
Please e-mail a letter describing your interest and long-term goals, a curriculum vitae and three letters of reference to Dr. Susan Wray: wraysninds.nih.gov, Cellular and Developmental Neurobiology, NINDS, NIH (http://intra.ninds.nih.gov/Lab.asp?Org_ID=42)
