We conduct detailed studies of brain organization and neurocognitive abilities in individuals who have had a brain injury. This research program allows us to test hypotheses about how the brain works and how it responds to injury. The insights gained can help design personalized brain mapping protocols in neurosurgery patients, and test hypotheses about the factors that may encourage and hinder recovery.
Neural systems supporting activities of daily living
Everyday interactions with common objects require the integration of conceptual knowledge about objects and actions with real-time sensory information about object and body position and volumetric structure. The ability to successfully interact with everyday objects involves representations of many aspects of the body and the world. Each of those processes can be localized with functional MRI and lesion-behavior mapping.
Our research aims to i) develop and test a neurocognitive model of object directed actions, ii) apply that model to understand how brain lesions disrupt activities of daily living, and iii) understand how recovery from deficits can be facilitated. This research is funded by the National Institute of Health.
Optimizing Functional Mapping during Awake Brain Surgery
Electrical stimulation mapping during awake neurosurgery is a clinical technique to confirm person-specific functional organization in real time, during invasive neurosurgical procedures. Our group has partnered with clinical colleagues to innovate how abilities such as language, memory, motor function, and music can be mapped in the human brain during awake brain surgery.
Our research on awake brain mapping has been anchored by our experience with the neurosurgical teams at the University of Rochester Medical School (see Mahon et al., 2019, JoVE), and the University of Pittsburgh Medical Center.
A central goal of this work is to identify the most sensitive task to map critical functions in individual patients. To accomplish this, we use per-operative functional and structural MRI, and detailed neurocognitive testing. This allows us to develop tests that can then be used during awake surgery.
