ANDRÉS PARRA MARTÍN, PHD
Dr. Andres Parra joined Max Planck Florida Institute for Neuroscience at the end of 2012. He is mainly interested in understanding the monosynaptic connections underlying orientation and direction selectivity in single layer 2/3 pyramidal neurons of the primary visual cortex. His project employs techniques such as in vivo patch clamp and viral infection, as well as multiphoton calcium imaging.
Dr. Parra received his PhD in Neuroscience on January 2012 in the department of physiology of the University Miguel Hernandez (UMH), Spain. During his PhD studies he characterized the functional activity of corneal cold thermoreceptors and their involvement in the regulation of the basal tearing flow in mice. Part of this characterization was done in the nerve ending of the receptor by extracellular recordings and in the soma with patch clamp whole cell configuration techniques. He discovered that the ongoing activity of these types of somatosensory receptors is required for the maintenance of the basal precorneal tear film.
