This book describes methods for statistical brain imaging data
analysis from both the perspective of methodology and from the
standpoint of application for software implementation in
neuroscience research. These include those both commonly used
(traditional established) and state of the art methods. The former
is easier to do due to the availability of appropriate software. To
understand the methods it is necessary to have some mathematical
knowledge which is explained in the book with the help of figures
and descriptions of the theory behind the software. In addition,
the book includes numerical examples to guide readers on the
working of existing popular software. The use of mathematics is
reduced and simplified for non-experts using established methods,
which also helps in avoiding mistakes in application and
interpretation. Finally, the book enables the reader to understand
and conceptualize the overall flow of brain imaging data analysis,
particularly for statisticians and data-scientists unfamiliar with
this area. The state of the art method described in the book has a
multivariate approach developed by the authors' team. Since brain
imaging data, generally, has a highly correlated and complex
structure with large amounts of data, categorized into big data,
the multivariate approach can be used as dimension reduction by
following the application of statistical methods. The R package for
most of the methods described is provided in the book.
Understanding the background theory is helpful in implementing the
software for original and creative applications and for an unbiased
interpretation of the output. The book also explains new methods in
a conceptual manner. These methodologies and packages are commonly
applied in life science data analysis. Advanced methods to obtain
novel insights are introduced, thereby encouraging the development
of new methods and applications for research into medicine as a
neuroscience.
Regular physical exercise is associated with substantial health
benefits. Recent evidence not only holds for cardiovascular effects
promoting "physical health," but also for the central nervous
system believed to promote "brain health." Moderate physical
exercise has been found to improve learning, memory, and
attentional processing, with recent research indicating that
neuroprotective mechanisms and associated plasticity in brain
structure and function also benefit. Physical exercise is also
known to induce a range of acute or sustained psychophysiological
effects, among these mood elevation, stress reduction, anxiolysis,
and hypoalgesia. Today, modern functional neuroimaging techniques
afford direct measurement of the acute and chronic relation of
physical exercise on the human brain, as well as the correlation of
the derived physiological in vivo signals with behavioral outcomes
recorded during and after exercise. A wide range of imaging
techniques have been applied to human exercise research, ranging
from electroencephalography (EEG), magnetoencephalography (MEG),
near infrared spectroscopy (NIRS), magnetic resonance imaging (MRI)
to positron emission tomography (PET). All of these imaging methods
provide distinct information, and they differ considerably in terms
of spatial and temporal resolution, availability, cost, and
associated risks. However, from a "multimodal imaging" perspective,
neuroimaging provides an unprecedented potential to unravel the
neurobiology of human exercise, covering a wide spectrum ranging
from structural plasticity in gray and white matter, network
dynamics, global and regional perfusion, evoked neuronal responses
to the quantification of neurotransmitter release. The aim of this
book is to provide the current state of the human neuroimaging
literature in the emerging field of the neurobiological exercise
sciences and to outline future applications and directions of
research.

Many will remember the segment of "The Sorcerer's Apprentice" in
the Disney film Fantasia; it is a perfect metaphor for medical
imaging as it stands today. The apprentice magician tests his
nascent skills at sorcery by bringing common household items to
life and putting them to work. At first, things go well, but
eventually he loses control, and chaos ensues.
Medical imaging, too, could spin out of control. The benefits of
imaging are undeniable. In the past thirty years, innovations like
CT, MRI, and PET scanning have not only markedly reduced clinical
risk for patients but have also transformed medical practice. Its
costs, however, have grown explosively, to the point where imaging
expenses have become a political issue. The aggressive adoption of
imaging technology has raised issues about the role of
inappropriate economic incentives and the role of defensive
medicine in driving up medical costs.
Radiologists have utilized imaging technology to transform their
practice from a pure diagnostic discipline into a curative one.
Radiologists are among the most successful knowledge workers in the
entire economy, leveraging digital information technology and
Internet connectivity to become the first global medical
discipline. Imaging is poised to make a further quantum advance -
into the workings of the human cell and the molecular biology of
complex disease.
Where is this remarkable technology, and the discipline which uses
it, headed? How can society make the most responsible use of this
powerful new tool? How will imaging and radiologists reshape
medical practice? These questions will be answered by The
Sorcerer's Apprentice.
