Fast transient networks in spontaneous human brain activity (2014, background): “However, an important limitation in our understanding of spontaneous activity is how the low frequency fluctuations typically associated with RSNs are related to the much faster timescales of cognitive and sensory processing (Heeger and Ress, 2002; Deco and Corbetta, 2011; Raichle, 2011; Siegel et a”
When size matters: attention affects performance by contrast or response gain (2010, background): “Although it is known that the fMRI signal is triggered by metabolic demands of neural activity, the details of this process are only partially understood, and it is likely that a mixture of synaptic and spiking activity may contribut”
The Brain's Default Network (2008, neutral): “The methods that have revealed the default network are based on hemodynamic measures of blood ﬂow that are indirectly linked to neural activity (Raichle 1987, Heeger & Ress 2002).”
Recall of fear extinction in humans activates the ventromedial prefrontal cortex and hippocampus in concert. (2007, result): “Considering that BOLD responses can reflect either exciatory or inhibitory processes (Heeger and Ress 2002), the ositive correlation observed herein is consistent with activation f inhibitory networks within this structure.”
Regulation of retinal blood flow in health and disease. (2008, background): “, 1997); (b) increased delivery of glucose required by the astrocytes which play a crucial role in neurotransmitter recycling (Heeger and Ress, 2002); (c) increased delivery of oxygen required by the increased activity in neurons and axons (Attwell and Laughlin, 2001); and (d) NO production due to a”
The Neural Correlates of Third-Party Punishment (2008, neutral): “…11.12 s, 0.44; respectively) and accounting for a hemodynamic peak rise time of about 5 s poststimulus (Boynton et al., 1996; Friston et al., 1994; Heeger and Ress, 2002), peridecision activity should occur approximately 17 s after trial onset, which corresponds well with the time of peak…”
Alterations in the BOLD fMRI signal with ageing and disease: a challenge for neuroimaging (2003, background): “The few studies that have examined this have generally supported a roughly linear relationship (for a review on the topic, see Ref”
Neurocinematics: The Neuroscience of Film (2008, methodology): “…resonance imaging (fMRI) offer an opportunity to measure brain activity during free viewing of films. fMRI utilizes a magnetic resonance imaging (MRI) scanner, like that used routinely for clinical evaluation of human anatomy, which is reprogrammed to get a time-series of 3D images of brain…”
The neural basis of the blood-oxygen-level-dependent functional magnetic resonance imaging signal. (2002, neutral): “…behavioural state, and the one recently used to examine quantitatively the relationship of the BOLD signal to neural activity by comparing human fMRI data with electrophysiological data in monkeys performing the same task (Heeger et al. 2000; Rees et al. 2000; for a review see Heeger & Ress 2002).”
Resting-state functional connectivity in the human brain revealed with diffuse optical tomography (2009, positive): “In addition, DOT provides a more comprehensive assessment of hemodynamics and metabolism than the blood oxygenation leveldependent (BOLD) signal, due to BOLD's complicated connection to the underlying neurovascular coupling (Raichle and Mintun, 2006; Heeger and Ress, 2002).”
UI Dark Patterns and Where to Find Them: A Study on Mobile Applications and User Perception (2020, background): “Neuromar-keting is a new ﬁeld that uses techniques such as fMRI [50], EEG [53], and gaze detection [55] to investigate the effects of marketing inputs [29, 53, 94, 96].”
