Antidepressants are widely prescribed, but their efficacy relative to placebo is modest, in part because the clinical diagnosis of major depression encompasses biologically heterogeneous conditions. Here, we sought to identify a neurobiological signature of response to antidepressant treatment as
The phrase “Pavlov’s dogs” has long evoked images of bells, food and salivating dogs. Even though this tried-and-true model of repetitive patterns mimics a variety of learning processes, what happens on a cellular level in the brain isn’t clear.
This review focuses on possible contributions of neural dedifferentiation to age-related cognitive decline. Neural dedifferentiation is held to reflect a breakdown in the functional specificity of brain regions and networks that compromises the fidelity of neural representations supporting episodic memory and related cognitive functions.
Our state of arousal–being fearful, agitated, or calm–can significantly affect our ability to make optimal decisions, judgments, and actions in real-world dynamic environments. Imagine, for instance, walking across a balance beam. https://neurosciencenews.com/neurofeedback-arousal-performance-10881/
A study published in the journal Neuroimage: Clinical found that patients with Major Depressive Disorder (MDD), who had recovered from symptoms, were able to strengthen some of their brain connections whilst thinking about guilt-evoking memories, thereby increasing their self-esteem. https://neurosciencenews.com/neurofeedback-depression-15058/
Our brain uses filter systems to efficiently manage the gigantic amounts of information that flow over us. Neuronal alpha oscillations are among them. They help to reduce the flow of information in certain brain regions. https://neurosciencenews.com/neurofeedback-learning-10561/
Researchers using functional MRI (fMRI) have found that neurofeedback training has the potential to reduce the severity of tinnitus or even eliminate it, according to a study presented today at the annual meeting of the Radiological Society of North
