Research in this laboratory concentrates on the neural mechanisms of perception and object recognition. Although our basic research revolves around vision, a number of independent collaborators are also investigating the relationship between neural activity and perception using other sensory modalities. I firmly believe that such scientific questions require a multimodal methodological approach that integrates information obtained from single units with that derived from mass action potentials as well as from a number of activity-related, surrogate signals such as those monitored during noninvasive experiments. Parallel to our ongoing research, therefore, we are also working to develop methodologies that will permit us to study neural networks in the context of behavioral paradigms. We have already designed and implemented two high-field magnetic resonance imaging systems for functional, anatomical and spectroscopic imaging. The systems are endowed with all the necessary hard- and software to conduct simultaneous imaging and recordings, and they are being used to study the function, connectivity, and neurochemistry of the non-human primate brain. Furthermore, while continuing to exploit traditional neuroimaging in our experiments, we are also investigating the relationship of neural activity to the MR-measurable hemodynamic responses and experimenting with methods that do not rely on hemodynamic responses at all. In the context of the last-named project, a group of synthetic and coordination chemists in my laboratory are attempting to synthesize and evaluate MR-detectable smart probes that change magnetic properties as a function of the concentration of ions and molecules involved in neural signaling. Smart contrast agents, if designed and tested appropriately, promise to revolutionize invasive neuroimaging and would represent a quantum leap forward in signal-to-noise ratio, spatial detail and specificity, while affording unprecedented temporal resolution.

Nikos K. Logothetis is director of the department “Physiology of Cognitive Processes” at the Max Planck Institute for Biological Cybernetics (MPIK), in Tübingen, Germany. He received a B.S. in mathematics from the University of Athens, a B.S. in biology from the University of Thessaloniki, and his Ph.D. in human neurobiology from the Ludwig-Maximilians University in Munich. In 1985 he moved to the Brain and Cognitive Sciences Department of M.I.T., where he initially worked as a postdoctoral fellow and later as Research Scientist. In 1990 he joined the faculty of the Division of Neuroscience at the Baylor College of Medicine. Seven years later he moved to the Max Planck Institute for Biological Cybernetics to continue his work on the physiological mechanisms underlying visual perception and object recognition.

In addition to visual cognition, his work at MPIC includes auditory perception and multisensory integration, as well as studies of plasticity and neuromodulation. Parallel to this ongoing research, a number of methods have been developed that permit the study of neural networks in the context of behavioral paradigms. Two high-field magnetic resonance imaging systems were designed and implemented for functional, anatomical and spectroscopic imaging. They permit simultaneous imaging and intracortical recordings and are being used to study the function, connectivity, and neurochemistry of the non-human primate brain, as well as the relationship of neural activity to the MR-measurable hemodynamic responses. Last but not least a group of synthetic and coordination chemists at MPIC are attempting to synthesize and evaluate MR-detectable smart probes that change magnetic properties as a function of the concentration of ions and molecules involved in neural signaling.

Since 1992 Nikos K. Logothetis has been Adjunct Professor of Neurobiology at the Salk Institute in San Diego, since 1995 Adjunct Professor of Ophthalmology at the Baylor College of Medicine, Houston, Associate of the Neurosciences Institute, San Diego, Senior Visiting Fellow in University College, London, Adjunct Professor in the Department of Cognitive and Neural Systems and of Cognitive and Neural Systems in the College of Arts and Sciences, both at the Boston University, Massachusetts, a  faculty member at the Victoria University of Manchester (VUM) in England, and Honorary Professor in the Department of Biology at the University of Tübingen.
