Intraoperative Human Functional Brain Mapping Using Optical Intrinsic Signal Imaging
Functional brain mapping strives to describe the brain’s organization as a mosaic of distinct regions, each of which subserves a particular function. Advances in our understanding of functional brain organization over the past decades have been propelled by the availability of increasingly sophisticated methods for assessing various aspects of neuronal activity in vivo. These methods can be bro...
متن کامل-Amyloid, Blood Vessels, and Brain Function
Cerebrovascular disease and Alzheimer disease are common diseases of aging and frequently coexist in the same brain. Accumulating evidence suggests that the presence of brain infarction, including silent infarction, influences the course of Alzheimer disease. Conversely, there is evidence that -amyloid can impair blood vessel function. Vascular -amyloid deposition, also known as cerebral amyloi...
متن کاملCommentary: Selective Development of Anticorrelated Networks in the Intrinsic Functional Organization of the Human Brain
We examined the normal development of intrinsic functional connectivity of the default network (brain regions typically deactivated for attention-demanding tasks) as measured by resting-state fMRI in children, adolescents, and young adults ages 8-24 years. We investigated both positive and negative correlations and employed analysis methods that allowed for valid interpretation of negative corr...
متن کاملFunctional Brain Mapping
FUNCTIONAL BRAIN MAPPING may be useful for both preoperative planning and intraoperative neurosurgical decision making. “Gold standard” functional studies such as direct electrical stimulation and recording are complemented by newer, less invasive techniques such as functional magnetic resonance imaging. Less invasive techniques allow more areas of the brain to be mapped in more subjects (inclu...
متن کاملEvaluation of the Contribution of Signals Originating from Large Blood Vessels to Signals of Functionally Specific Brain Areas
The fusiform face area (FFA) is known to play a pivotal role in face processing. The FFA is located in the ventral region, at the base of the brain, through which large blood vessels run. The location of the FFA via functional MRI (fMRI) may be influenced by these large blood vessels. Responses of large blood vessels may not exactly correspond to neuronal activity in a target area, because they...
