Modern neuroimaging tools allow unprecedented opportunities for understanding
brain neuroanatomy and function in health and disease. Each available technique
carries with it a particular balance of strengths and limitations, such that converging
evidence based on multiple methods provides the most powerful approach for
advancing our knowledge in the fields of clinical and cognitive neuroscience. In
addition to offering fine-grained in-vivo neuroanatomical specification, neuroimaging
methods also provide the opportunity to non-invasively explore brain function.
The rate of technological progress is encouraging increasingly sophisticated lines of
enquiry in cognitive neuroscience and shows no sign of slowing down in the
foreseeable future. Nevertheless, it is unlikely that even the strongest advocates of the
cognitive neuroscience approach would maintain that advances in cognitive theory
have kept in step with methods-based developments. There are several candidate
reasons for the failure of neuroimaging studies to convincingly resolve many of the
most important theoretical debates in the literature.
Brain morphology is in constant change from the very beginning of the neurodevelopment in human beings. The characterization of the brain morphology and its biological implications on a specific subject is a complex task which requires efficient computational approaches. Radiology has traditionally assessed the main brain changes in different alterations from a macroscopic point of view, thus, not considering subtle changes as a results of neuronal plasticity.

In Chapter 5, Carrascosa Romero and de Cabo de la Vega consider the relevance of
genetics and brain imaging findings in the diagnosis of diseases which result from
abnormal development or neoplasia of cells derived from the neural crest
(neurocristopathies). Koga and Saito (Chapter 6) provide a beautifully illustrated
discussion of the use of neuroimaging tools to guide gamma knife radiosurgery.
While history and examination will always remain the foundation of neurolog-
ical diagnosis, MRI and CT have now become the most important diagnostic
tests used by neurologists and neurosurgeons. These tests are critical not only
for confirming clinical diagnosis, but in many cases will give additional infor-
mation absolutely essential to patient care. Modern clinical diagnosis and treat-
ment of central nervous system disorders relies heavily upon neuroimaging. In
some cases, the optimal management of clinical problems affecting patients
with brain tumors, strokes, etc.
Neuroimaging technology has progressed considerably
during recent decades. Neuroimaging studies can
be an invaluable part of the diagnostic workup of psychiatric
patients. However, it can be difficult to determine
which clinical situations call for the use of neuroimaging
studies and which do not. In addition, it is
often unclear what type of neuroimaging study should

The posttraumatic stress disorder project in Brazil: neuropsychological, structural and molecular neuroimaging studies in victims of urban violence
Magnetic resonance spectroscopy (MRS), unlike conventional magnetic resonance
imaging (MRI), provides information on the brain’s chemical environment (rather than
neuroanatomical structure) and the data are most commonly presented as line spectra.
This capacity for determining brain metabolite concentrations provides the basis for
clinical investigation of, and differentiation between, neurological and neurosurgical
In order to better understand the clinical manifestations and neuroimaging data of those
dissociative disorders, which have as hallmark inability to recall personal past events, we
will briefly review the current classifications of the long-term memory systems. Two
overlapping classifications currently dominate the memory research literature – the one that
was initiated by Larry Squire and the one that was advanced by Endel Tulving. In Squire’s
classification, a main distinction is made between declarative and non-declarative memory.
These criteria are
classified into its safety profile, performance within the GI tract and technological
aspects of its development. The criteria are further dependent on the specific purpose
of the strain and on the location for the expression of the specific property. With
regards to safety, the probiotic strain must be of human origin, isolated from the
gastrointestinal tract (GIT) of healthy individuals.
In this regard, available evidence shows that
while morphine and heroin are liable to attenuate the immune response, long-acting opioids
that are used in withdrawal treatment, such as methadone and buprenorphine, are largely
devoid of immunosuppressive activity. Opioids can also influence the immune function
through the activation of the descending pathways of the hypothalamus-pituitary axis
(HPA) and the sympathetic nervous system (Vallejo et al., 2004).
