Lab Research Areas

Integration is the hallmark of cognition. This is true at both the neural and behavioral levels. Even the single action potential is, above all, the product of large-scale integration across multiple brain regions. The simplest, everyday behaviors such as remembering a face, or opening a door, are in actuality incredibly complex, supported by multiple cognitive domains including perception, action, memory, learning, and social cognition. The Ramot Lab studies these large-scale interactions and how they support the network level synthesis of interdependent cognitive processes.

Researchers build and test hypotheses on the relationships between behavior and network characteristics, such as functional connectivity and dynamics.  Using a variety of imaging methods including fMRI and DTI, they are able to examine the whole brain at once, and uncover large-scale interactions across different network nodes. This is combined with patients’ electrocortical recordings to study the effects of network dynamics. On the behavioral side, our researchers  develop more reliable and objective behavioral measures to better characterize the link between networks and behavior. Finally, they move away from correlation and begin asking questions about causality, by directly manipulating the networks using covert neurofeedback, and evaluating the effects on behavior.

Scholar Profile

Dr. Michal Ramot is a faculty member in the Department of Neurobiology at the Weizmann Institute. She completed a postdoc at the National Institutes of Health in Bethesda, Maryland and a PhD at Hebrew University’s Interdisciplinary Centre for Neural Computation.

Dr. Ramot’s research examines the neural mechanisms behind different aspects of cognition. Her main breakthroughs were in showing how spontaneous brain activity contributes to different cognitive skills, mainly visual perception and memory formation. In her training she mastered an impressive set of techniques that is required to do brain research in humans, including electroencephalography (EEG), intracranial recordings (ECog), and functional-magnetic-resonance-imaging (fMRI).

Dr. Ramot also developed a novel covert neurofeedback technique. With this technique, subjects are positively reinforced, based on their real-time brain activity measured with fMRI, and conditioned towards desired brain activity. This method allows scientists to tune or train brain network configurations directly. Dr. Ramot demonstrated that such covert feedback can induce plasticity in human brain networks. Previously, there was evidence of causality between brain networks and behaviors primarily in animal models; Dr. Ramot’s method offers a means of attaining evidence of this causality in humans, in a non-invasive manner.

Currently, Dr. Ramot is applying her method and others to explore how different large-scale neural networks in the human brain, which integrate various cognitive domains, give rise to particular behaviors.

In the long term, Dr. Ramot hopes to develop the field of neurofeedback in the direction of clinical application. Her work could help clinicians to verify the causes of aberrant networks, and even to provide methods for rewiring brain networks to modulate neurological and psychiatric conditions and potentially enhance brain functions such as memory, learning, and perception.
