Evidence of functional connectivity between auditory cortical areas revealed by amplitude modulation sound processing.
The human auditory cortex includes several interconnected areas. A better understanding of the mechanisms involved in auditory cortical functions requires a detailed knowledge of neuronal connectivity between functional cortical regions. In human, it is difficult to track in vivo neuronal connectivity. We investigated the interarea connection in vivo in the auditory cortex using a method of dir...
متن کاملThalamic control of functional cortical connectivity
The thalamus is an evolutionarily conserved structure with extensive reciprocal connections to cortical regions. While its role in transmitting sensory signals is well-studied, its broader engagement in cognition is unclear. In this review, we discuss evidence that the thalamus regulates functional connectivity within and between cortical regions, determining how a cognitive process is implemen...
متن کاملFunctional Connectivity Magnetic Resonance Imaging Reveals Cortical Functional Connectivity in the Developing Brain
Background and Purpose: Resting functional MRI was utilized to depict brain regions exhibiting temporal synchronization, also known as resting brain functional connectivity (rfc). This study aims to determine the temporal and spatial patterns of rfc in healthy pediatric subjects between 2wks and 2yrs old. Methods: Rfc studies were performed on 85 children: 38 neonates (2-4 wks), 26 1yr olds and...
متن کاملFunctional connectivity MR imaging reveals cortical functional connectivity in the developing brain.
BACKGROUND AND PURPOSE Unlike conventional functional MR imaging where external sensory/cognitive paradigms are needed to specifically activate different regions of the brain, resting functional connectivity MR imaging acquires images in the absence of cognitive demands (a resting condition) and detects brain regions, which are highly temporally correlated. Therefore, resting functional MR imag...
متن کاملAltered resting-state functional connectivity in cortical networks in psychopathy.
Psychopathy is a personality disorder characterized by callous antisocial behavior and criminal recidivism. Here we examine whether psychopathy is associated with alterations in functional connectivity in three large-scale cortical networks. Using fMRI in 142 adult male prison inmates, we computed resting-state functional connectivity using seeds from the default mode network, frontoparietal ne...
