What is functional connectivity in fMRI?

Functional connectivity is defined as the temporal dependency of neuronal activation patterns of anatomically separated brain regions and in the past years an increasing body of neuroimaging studies has started to explore functional connectivity by measuring the level of co-activation of resting-state fMRI time-series …

What is connectivity software used for?

Connectivity Software means software drivers and small applications, in some cases unseen by the user, typically provided by Microsoft, SBC Sub, and Third Party vendors to allow networking drivers on the user’s PC to communicate with the network being used, as mutually agreed by SBC Sub or Operating Partnership.

How do you cite a Conn toolbox?

To cite CONN in your work please include one or several of the following references:

CONN toolbox (www.nitrc.org/projects/conn, RRID:SCR_009550)

What is a functional connectivity map?

Functional connectivity mapping was first described by Biswal et al. (1995) in a seminal paper, revealing correlations between brain regions that are synchronized in time, through spontaneous fluctuations of activity, while the brain regions themselves may be quite distant.

What is functional connectivity in brain?

On a general note, functional connectivity is defined as the statistical relationships between cerebral signals over time and thus potentially allows conclusions to be made regarding the functional interactions between two or more brain regions.

What is functional network connectivity?

Functional network connectivity (FNC) is a method of analyzing the temporal relationship of anatomical brain components, comparing the synchronicity between patient groups or conditions.

What does connectivity mean for computers?

In general terms, connectivity is the ability to connect systems or application programs. Ideally, these connections are established without requiring many changes to the applications or the systems on which they run.

How do you cite Conn?

For citation purposes, refer to a specific provision of the General Statutes first by title, then by section. For example, if you are discussing a law on speeding, you would look at Title 14, Section 219, which would be cited simply as “Conn.

What does functional connectivity represent?

Functional connectivity refers to the statistical relationship between specific physiological signals in time and are generally assessed using techniques such as functional magnetic resonance imaging (fMRI), electroencephalography (EEG) or magnetic electroencephalography (MEG).

What is functional connectivity neuroscience?

Functional connectivity refers to the functionally integrated relationship between spatially separated brain regions. These methods have been used to show that functional connectivity is related to behavior in a variety of different tasks, and that it has a neural basis.

How is functional connectivity measured in fMRI data?

In terms of fMRI data, functional connectivity may be investigated on measurements that are obtained while the subject is passively lying in the scanner (resting state) or on fMRI data recorded during a particular task (e.g., Ebisch et al., 2013 ).

How is functional connectivity assessed in neural systems?

In summary, functional connectivity may thus be assessed using various data modalities and analysis approaches, rendering it a broad concept rather than a particular method. This article has reviewed different approaches to characterizing functional integration in neural systems on the basis of neuroimaging data.

How does ADHD affect the functional connectivity network?

A review of FC studies in ADHD reported altered connectivity within a default mode network of structures active during task-free processes and disrupted interactions between this network and frontostriatal attentional systems ( Liston et al., 2011 ).

Is it possible to have strong functional connectivity?

Strong functional connectivity may hence be observed even if structural connections are weak or absent, although in most cases, these two aspects of brain connectivity show at least some level of convergence ( Eickhoff et al., 2010 ).
