Dr. Angela Pignatelli is a Senior Researcher in Physiology at the Department of Neuroscience and Rehabilitation—Section of Human Physiology, University of Ferrara, Italy. She holds a Ph.D. in Neurobiology and Neurophysiology and a Degree in Biological Sciences obtained at the University of Ferrara, Italy. The main subject of her investigations over the last 20 years has been the electrophysiological characterization of dopaminergic cells in the olfactory bulb, including the neurogenesis process. Her main study concerned the neurogenesis of dopaminergic cells in the mammalian brain and the study of the mechanisms by which olfactory sensory information is processed in the olfactory bulb. In the past, Dr. Pignatelli was interested in retina research, in particular, on the effects of manipulations of divalent ion concentrations in synaptic transmission between photoreceptor and second-order cells in the vertebrate retina. The conclusions of these studies have led to a complete reinterpretation of the so-called “calcium-independence” of synaptic transmission at this level.
