Negative functional MRI response correlates with decreases in neuronal activity in monkey visual area V1 (2006, neutral): “A competing perspective suggests that the negative hemodynamic and BOLD responses reflect suppression of neuronal activit”
Sustained negative BOLD, blood flow and oxygen consumption response and its coupling to the positive response in the human brain. (2002, positive): “Additional support for our choice of the baseline condition is given by the physiological definition of a baseline condition of brain function, based on the oxygen extraction fraction (OEF) (Raichle et al., 2001).”
The origins of metamodality in visual object area LO: Bodily topographical biases and increased functional connectivity to S1 (2016, neutral): “, 2002, 2006) have been studied mainly in the context of the default mode network (DMN, Greicius and Menon, 2004; Raichle and Snyder, 2007; Raichle et al., 2001).”
Neural syntax: cell assemblies, synapsembles and readers (2010, neutral): “Reader mechanisms of spiking activity at very long timescales may be exemplified, e.g., by the autonomic nervous system and the 0.1 Hz periodicity of the brain’s ‘‘default networks’’ (Raichle et al., 2001).”
Altered functional connectivity in early Alzheimer's disease: A resting‐state fMRI study (2007, positive): “…Fransson [2005] revealed two networks that were similar to those found by Fox et al. [2005], and suggested that the default mode of brain function [Raichle et al., 2001] might be augmented with a second mode of brain function which reflected the existence of an extrospectively oriented attention…”
Amyloid deposition is associated with impaired default network function in older persons without dementia (2009, positive): “It is intriguing, however, that brain regions particularly vulnerable to early amyloid deposition, appear to overlap a set of heteromodal cortices, often collectively labeled the ‘‘default network’’ (Raichle et al., 2001; Buckner et al., 2008).”
Functional-Anatomic Fractionation of the Brain's Default Network (2010, positive): “received considerable attention because of the possibility that it participates in important functions that reflect more than a quiescent or idling brain state (Raichle et al., 2001; Gusnard and Raichle, 2001).”
Brain Mechanisms Supporting Modulation of Pain by Mindfulness Meditation (2011, positive): “However, there was significantly greater default-mode-related brain activation (medial PFC) in the rest condition (Raichle et al., 2001) compared with the ATB condition.”
Mapping the self in the brain's default mode network (2016, positive): “…– was first identified by an analysis of nuclear imaging studies that showed that these brain regions consistently displayed higher levels of activity during passive task conditions than during conditions that required goal-directed task performance (Shulman et al., 1997; Raichle et al., 2001).”
Fate of unattended fearful faces in the amygdala is determined by both attentional resources and cognitive modulation (2005, neutral): “It has been suggested that cognitive and emotional systems interact in a reciprocal fashion (Drevets and Raichle, 1998; Mayberg et al., 1999).”
