The role of the posterior cingulate cortex in cognition and disease
The posterior cingulate cortex is a highly connected and metabolically active brain region.
Recent studies suggest it has an important cognitive role, although there is no consensus …

Fractionating the default mode network: distinct contributions of the ventral and dorsal posterior cingulate cortex to cognitive control
R Leech, S Kamourieh, CF Beckmann… - Journal of …, 2011 - Soc Neuroscience
The posterior cingulate cortex (PCC) is a central part of the default mode network (DMN)
and part of the structural core of the brain. Although the PCC often shows consistent …

The default mode network in cognition: a topographical perspective
The default mode network (DMN) is a set of widely distributed brain regions in the parietal,
temporal and frontal cortex. These regions often show reductions in activity during attention-…

Network dysfunction after traumatic brain injury
Diffuse axonal injury after traumatic brain injury (TBI) produces neurological impairment by
disconnecting brain networks. This structural damage can be mapped using diffusion MRI, …

[HTML][HTML] The entropic brain: a theory of conscious states informed by neuroimaging research with psychedelic drugs
Entropy is a dimensionless quantity that is used for measuring uncertainty about the state of
a system but it can also imply physical qualities, where high entropy is synonymous with …

Neural correlates of the LSD experience revealed by multimodal neuroimaging
Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the
human brain have never been studied before with modern neuroimaging. Here, three …

White matter damage and cognitive impairment after traumatic brain injury
White matter disruption is an important determinant of cognitive impairment after brain injury,
but conventional neuroimaging underestimates its extent. In contrast, diffusion tensor …

Echoes of the brain within the posterior cingulate cortex
There is considerable uncertainty about the function of the posterior cingulate cortex (PCC).
The PCC is a major node within the default mode network (DMN) and has high metabolic …

Salience network integrity predicts default mode network function after traumatic brain injury
Efficient behavior involves the coordinated activity of large-scale brain networks, but the
way in which these networks interact is uncertain. One theory is that the salience network (SN)—…
