Can we predict real-time fMRI neurofeedback learning success from pretraining brain activity?

Journal article Hum Brain Mapp · October 1, 2020 Neurofeedback training has been shown to influence behavior in healthy participants as well as to alleviate clinical symptoms in neurological, psychosomatic, and psychiatric patient populations. However, many real-time fMRI neurofeedback studies report lar ... Full text Link to item Cite

Pyneal: Open Source Real-Time fMRI Software.

Journal article Front Neurosci · 2020 Increasingly, neuroimaging researchers are exploring the use of real-time functional magnetic resonance imaging (rt-fMRI) as a way to access a participant's ongoing brain function throughout a scan. This approach presents novel and exciting experimental ap ... Full text Open Access Link to item Cite

Expected Reward Value and Reward Uncertainty Have Temporally Dissociable Effects on Memory Formation.

Journal article J Cogn Neurosci · October 2019 Anticipating rewards has been shown to enhance memory formation. Although substantial evidence implicates dopamine in this behavioral effect, the precise mechanisms remain ambiguous. Because dopamine nuclei have been associated with two distinct physiologi ...

Single session real-time fMRI neurofeedback has a lasting impact on cognitive behavioral therapy strategies.

Journal article Neuroimage Clin · 2018 To benefit from cognitive behavioral therapy (CBT), individuals must not only learn new skills but also strategically implement them outside of session. Here, we tested a novel technique for personalizing CBT skills and facilitating their generalization to ... Full text Open Access Link to item Cite

Real-Time Functional Magnetic Resonance Imaging

Journal article eLS · 2018 Real-time functional magnetic resonance imaging (rt-fMRI) is an increasingly popular noninvasive technique used to study brain function in ‘real time’. In contrast to traditional fMRI, rt-fMRI allows researchers to access and manipulate neu- roimaging data ... Full text Link to item Cite

Motivation and Memory

Journal article Stevens' Handbook of Experimental Psychology and Cognitive Neuroscience · 2018 In this chapter we explore how motivation affects what we learn and subsequently remember. Our memories are not a perfect record of every event in our lives, meticulously recorded and replayed precisely whenever we desire. They are quite the opposite: Memo ... Full text Cite

Cognitive Neurostimulation: Learning to Volitionally Sustain Ventral Tegmental Area Activation.

Journal article Neuron · March 16, 2016 Activation of the ventral tegmental area (VTA) and mesolimbic networks is essential to motivation, performance, and learning. Humans routinely attempt to motivate themselves, with unclear efficacy or impact on VTA networks. Using fMRI, we found untrained p ... Full text Link to item Cite

Motivational influences on memory

Journal article Advances in Motivation and Achievement · January 1, 2016 Motivation significantly influences learning and memory. While a long history of research has focused on simple forms of associative learning, such as Pavlovian conditioning, recent research is beginning to characterize how motivation influences episodic m ...

Contributions of the hippocampus to feedback learning.

Journal article Cogn Affect Behav Neurosci · December 2015 Humans learn about the world in a variety of manners, including by observation, by associating cues in the environment, and via feedback. Across species, two brain structures have been predominantly involved in these learning processes: the hippocampus--su ... Full text Link to item Cite

Reward-related learning via multiple memory systems.

Journal article Biol Psychiatry · July 15, 2012 The application of a neuroeconomic approach to the study of reward-related processes has provided significant insights in our understanding of human learning and decision making. Much of this research has focused primarily on the contributions of the corti ... Full text Link to item Cite

Parallel contributions of distinct human memory systems during probabilistic learning.

Journal article Neuroimage · March 1, 2011 Regions within the medial temporal lobe and basal ganglia are thought to subserve distinct memory systems underlying declarative and nondeclarative processes, respectively. One question of interest is how these multiple memory systems interact during learn ... Full text Link to item Cite

Distinct mechanisms of impairment in cognitive ageing and Alzheimer's disease.
