Resting state functional connectivity data supports detection of cognition in the rodent brain
Learning is a process which induces plastic changes in the synapses and connections across different regions of the brain. It is hypothesized that these new connections can be tracked with resting state functional connectivity MRI. While most of the evidence of learning-induced plasticity arises from previous human data, data from sedated rats that had undergone training for either 1 day or 5 d...
متن کاملResting-State Functional Connectivity in Rat Brain
Introduction Synchronized low-frequency fluctuations in resting-state fMRI (1) have been used to investigate functional connectivity between brain areas. Recent studies demonstrate that this technique can be utilized in the study of Alzheimers disease (2), antidepressant effects (3), and default mode of brain networks (4). So far, most resting-state fMRI studies have been performed on humans...
متن کاملBrain Connections – Resting State fMRI Functional Connectivity
With the introduction of electroencephalography (EEG) in 1930, researchers began to explore spontaneous activity in the brain by recording the individual, independently of any task. Subsequently, evoked potential studies, where electrical potentials were recorded at the onset of a stimulus, marked a milestone in brain research. Utilizing such methods coupled with experimental psychology, resear...
متن کاملCognition and resting-state functional connectivity in schizophrenia.
Individuals with schizophrenia consistently display deficits in a multitude of cognitive domains, but the neurobiological source of these cognitive impairments remains unclear. By analyzing the functional connectivity of resting-state functional magnetic resonance imaging (rs-fcMRI) data in clinical populations like schizophrenia, research groups have begun elucidating abnormalities in the intr...
متن کاملWhole brain resting state functional connectivity abnormalities in schizophrenia.
BACKGROUND Schizophrenia has been associated with disturbances in brain connectivity; however the exact nature of these disturbances is not fully understood. Measuring temporal correlations between the functional MRI time courses of spatially disparate brain regions obtained during rest has recently emerged as a popular paradigm for estimating brain connectivity. Previous resting state studies ...
