A new study uses real-time fMRI neurofeedback to train people to regulate rumination, a common symptom of depression, by restoring healthy neural coupling between the posterior cingulate cortex and dorsolateral prefrontal cortex. The approach shows promise in reducing depressive symptoms while leaving anxiety intact.
Researchers found that fear memories start as broad associative memories, but become more specific over time. Individuals with high anxiety may struggle with integrating episodic memories, leading to persistent fear linked to cues.
A novel neurofeedback technique was developed to enhance awareness of mind-wandering, allowing individuals to manage this state more effectively. The study demonstrated significant enhancement in awareness after 20 minutes of neurofeedback, with no rewards or punishments used.
The study found that 'general psychiatric burden', 'social isolation', and 'depression/anxiety' worsened during the pandemic, with women more likely to be affected. Factors such as job type, income, and social connections played a significant role in these issues.
A multi-site, multi-disorder resting-state magnetic resonance image database was compiled to harmonize data from patients with various diseases, measured at 14 sites. The dataset comprises over 2,400 samples and includes 'traveling-subject' data to minimize inter-site differences.
A team of researchers found that when people use mental abstractions, the brain area that signals valuable information becomes highly active. This discovery could lead to new advances in basic research, education, rehabilitation, and artificial intelligence.
A new dataset from ATR Brain Information Communication Research Laboratory Group provides insights into Decoded Neurofeedback, a technique that uses AI and brain scanning to modify fear memories and boost confidence. The dataset includes five studies and could lead to new treatments for PTSD, phobias, and anxiety disorders.
A novel harmonization method was used to develop a generalizable brain network marker for major depressive disorder (MDD), based on resting-state fMRI data. The marker achieved approximately 70% generalization accuracy for an independent validation dataset, demonstrating its potential for clinical applications.
A team of researchers has successfully harnessed the power of the unconscious mind to make profitable decisions. By monitoring nonconscious brain activity, participants were able to learn and improve their choices without being aware of it. This breakthrough suggests that confidence may play a crucial role in guiding behavior.
A new neurofeedback approach, Decoded Neurofeedback (DecNef), has been explored in a preclinical study to treat chronic pain. The study found that DecNef enhances the brain's natural ability to control pain by boosting the 'endogenous pain control system', which is often dysfunctional in chronic pain patients.
Researchers propose a new 'Reciprocal Inhibition Model' of PTSD, explaining inhomogeneous symptoms by addressing variabilities at neural, attentional, and symptom levels. This model may aid tailored clinical treatment for individual patients.
Researchers developed an effective harmonization method to reduce site-related differences in resting-state fMRI data, reducing bias by 29% and improving signal-to-noise ratios by 40%. This allows for the development of practical brain-circuit-based biomarkers of psychiatric disorders regardless of imaging site.
Researchers have created an innovative method to alleviate common fears by reading out unconscious brain activity and associating feared objects with positive feelings. By using a mental exercise game and leveraging artificial intelligence algorithms, participants can become desensitized to phobic stimuli without encountering the feare...
Researchers manipulate brain connections to enhance or impair cognitive functions, offering potential therapeutic applications for psychiatric disorders and learning disabilities.
Researchers developed a method to read and amplify high confidence states using decoded neurofeedback, boosting participants' confidence without awareness. The effect was reversible, with confidence decreasing when the pattern was no longer detected.
