The physical mechanisms that underlie the relationship between brain and mind remain largely unknown. My line of research attempts to address this question by analyzing the activity of multiple single-neurons in the brains of non-human primates while they perform complex behavioral tasks. This technique allows high spatial and temporal resolution of neuronal activity. My work involves two lines of research employing the non-human primate model, with the broad objectives of: (1) understanding the neuronal mechanisms underlying cognitive processes, such as visual perception, working memory and attention; and (2) developing neurotechnologies, such as brain-machine interfaces to aid in the rehabilitation of patients with spinal cord or peripheral nerve injuries. In the first part of the talk I will discuss data from an ongoing experiment where I am studying information processing across prefrontal cortical regions during a visual working memory and distractor suppression task. In the second part of the talk I will describe the development of a brain-machine interface system where the activity of motor cortical signals were used by monkeys to control the movement of a robotic wheelchair.
Camilo Libedinsky is an assistant professor in the Department of Psychology at NUS, and has a joint appointment in the Singapore Institute for Neurotechnology, SiNAPSE. He specializes in awake-behaving non-human primate single-cell neurophysiology. He received his PhD in Neurosciences from Harvard Medical School under the supervision of Margaret Livingstone, then did a postdoc in the laboratory of Michael Chee at Duke-NUS followed by a second postdoc at the Singapore Institute for Clinical Sciences, A*STAR.
