Further Neuroimaging Evidence for the Deficit Subtype of Schizophrenia

Importance  The clinical heterogeneity of schizophrenia has hindered neurobiological investigations aimed at identifying neural correlates of the disorder.

Objective  To identify network-based biomarkers across the spectrum of impairment present in schizophrenia by separately evaluating individuals with deficit and nondeficit subtypes of this disorder. 372 more words

Functional Magnetic Resonance Imaging

fMRI basics

Functional magnetic resonance imaging, or fMRI, is a technique that provides information on brain activity. It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity – when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area. 2,007 more words

Magnetoencephalography

MEG basics

The magnetoencephalography or MEG is similar to EEG, however it measures changes in the associated magnetic fields of the neurons generating electrical potentials. Because the skull is transparent to magnetic fields, however, the spatial resolution of MEG is said to rival that of fMRI while maintaining the superior temporal resolution of EEG. 62 more words

Electroencephalography

EEG basics

Electroencephalography, or EEG, is the non-invasive measurement of the electrical activity of the brain by recording from electrodes placed on the scalp. When neurons are active, they fire action potentials, and send messages in the form of neurotransmitters to other neurons. 696 more words

Positron Emission Tomography

PET basics

Positron Emission Tomography, or PET, uses trace amounts of short-lived radioactive labeled molecules, usually called tracers or radio-tracers, which are injected into bloodstream to map functional processes in the brain. 2,063 more words
