Understanding Neuroimaging

Understanding stem cell-mediated brain repair through neuroimaging.

Transplantation of stem cells into the damaged brain can lead to behavioral recovery. However, at present, the mechanisms by which these cells exert their beneficial effects are still poorly understood. Survival, migration and differentiation are but a few of the factors that are thought to be involved in stem cell-mediated brain repair. It is hoped that neuroimaging, by MRI and PET, will provi...

Neuroimaging contributions to the understanding of discourse processes

Neuroimaging research is providing new types of information and insight about the cortical activity underlying discourse processing. Knowing the intensity and location of the brain activity during discourse comprehension adds significantly to the information provided by behavioral measures alone. The combination of neuroimaging data and behaviorally based discourse theories indicate that discou...

Understanding other minds: linking developmental psychology and functional neuroimaging.

Evidence from developmental psychology suggests that understanding other minds constitutes a special domain of cognition with at least two components: an early-developing system for reasoning about goals, perceptions, and emotions, and a later-developing system for representing the contents of beliefs. Neuroimaging reinforces and elaborates upon this view by providing evidence that (a) domain-s...

Understanding face perception by means of prosopagnosia and neuroimaging.

Understanding the human neuro-anatomy of face recognition is a long-standing goal of Cognitive Neuroscience. Studies of patients with face recognition impairment following brain damage (i.e., acquired prosopagnosia) have revealed the specificity of face recognition, the importance and nature of holistic/configural perception of individual faces, and the distribution of this function in the vent...
