1. Common functional neuroimaging techniques :( partial) changes in metabolism and blood oxygen measurement techniques (fmri, pet, nirs), by measuring the neuronal activity reflects the secondary (glucose metabolism and blood flow, blood oxygen changes) and behavior-related research neuronal activity, temporal and spatial resolution have the scientific basis for neurological research and clinical practice to a certain extent meet.
2.MRI studies brain anatomy(解剖), fMRI (Functional MRI) studies brain function.
3. proper nouns
session: a test to be carried out within a day of all scan
A continuous, uninterrupted image obtained by scanning: run / scan
experiment: To compare the experimenter combination of all the different types of experimental tasks
condition: an experimental operating task is a combination of a plurality of stimulation
A session can be composed of a single or a plurality of experiment, an experiment may be composed of single or multiple run, run by a single or a plurality of run composition, may comprise a plurality of run condition
4. Noise Source: main magnetic field inhomogeneities, field gradient nonlinearities, the thermal motion of the digital to analog converter, a new peach physiological breathing period fluctuation, the test head is movable
5. Data Preprocessing: structure and function as the image alignment, between the time correction level, the head movement correction, smoothing time, slow-wave (linear) drift, and the spatial normalization of brain recombinant voxel size, spatial smoothing.
6. brain connection: the human brain is a complex and efficient network systems, brain areas responsible for different functions based on the principle of separation and integration make up the network, thus completing the coordination of the internal functions, as well as to monitor and respond to the outside world. Functional feature of the brain tissue embodied mainly in the functional partitioning and integration functions, coordination between different functional brain areas, constituting a network topology of the brain, the brain called the connection.
7. Functional connection means a connection within the range defined in the anatomy, spatially separated nerve cell or nerve cell mass in a dynamic relationship between physical activity and elucidate whether the strength of brain sections and connection relationship of a connection relationship exists, having no direction sex; effect connection is described how a brain acts on other brain regions, i.e., transmission mode information set forth in the brain section, having directivity.
8. The functional characteristics of four connections: connection anatomic material basis, dynamic model is a dependency, is a manifestation of the relationship between, on the presence or absence of a statistically significant,
