Progressive modulation of resting-state brain activity during neurofeedback of positive-social emotion regulation networks

Neurofeedback allows for the self-regulation of brain circuits implicated in specific maladaptive behaviors, leading to persistent changes in brain activity and connectivity. Positive-social emotion regulation neurofeedback enhances emotion regulation capabilities, which is critical for reducing the severity of various psychiatric disorders. Training dorsomedial prefrontal cortex (dmPFC) to exert a top-down influence on bilateral amygdala during positive-social emotion regulation progressively (linearly) modulates connectivity within the trained network and induces positive mood. However, the processes during rest that interleave the neurofeedback training remain poorly understood. We hypothesized that short resting periods at the end of training sessions of positive-social emotion regulation neurofeedback would show alterations within emotion regulation and neurofeedback learning networks. We used complementary model-based and data-driven approaches to assess how resting-state connectivity relates to neurofeedback changes at the end of training sessions. In the experimental group, we found lower progressive dmPFC self-inhibition and an increase of connectivity in networks engaged in emotion regulation, neurofeedback learning, visuospatial processing, and memory. Our findings highlight a large-scale synergy between neurofeedback and resting-state brain activity and connectivity changes within the target network and beyond. This work contributes to our understanding of concomitant learning mechanisms post training and facilitates development of efficient neurofeedback training.

Subminiature multifunctional brain chip analyzes brain activity from multiple aspects

Neurotransmitters play a key role in the signal transmission process between neurons in the brain. If the concentration of neurotransmitters is higher or lower than normal, it triggers brain diseases for which neurotransmitters are injected as treatments. Therefore, the accurate measurement of neurotransmitter concentration is crucial for investigating the cause or during the treatment of brain diseases.

What can supermarkets tell researchers about older brains?

One key to unlocking what’s happening inside the brain of an Alzheimer’s patient could be hiding in the grocery store. That’s according to a new study by University of Arizona psychologists who looked at how the brain remembers spatial environments, especially those that are similar – such as two grocery stores from the same supermarket chain.

New optogenetic tool can control brain circuits, behavior, and emotion

Controlling signal transmission and reception within the brain circuits is necessary for neuroscientists to achieve a better understanding of the brain's functions. Communication among neuron and glial cells is mediated by various neurotransmitters being released from the vesicles through exocytosis. Thus, regulating vesicular exocytosis can be a possible strategy to control and understand brain circuits.

How Brains Seamlessly Switch Between Languages

Billions of people worldwide speak two or more languages. (Though the estimates vary, many sources assert that more than half of the planet is bilingual or multilingual.) One of the most common experiences for these individuals is a phenomenon that experts call “code switching,” or shifting from one language to another within a single conversation or even a sentence.

Quantum Sensors Measure Brain Activity with Pinpoint Accuracy

BRIGHTON, England, Dec. 2, 2021 — Quantum sensors could be used to indicate early biomarkers for brain diseases in space and time, based on the results of a University of Sussex (England) study. Researchers showed that quantum sensors, when used with magnetoencephalography (MEG), can track changes in the brain, such as a slowdown in brain activity, spatiotemporally.

FRONT PAGE: Neurobiologists Reveal How Value Decisions Are Coded Into Our Brains

Newswise — In 2019 University of California San Diego researchers discovered the area of the brain where “value decisions” are made. An area within the cerebrum known as the retrosplenial cortex (RSC), they found, is the site that we use to make value choices such as which restaurant we decide to visit for tonight’s dinner. We then update the RSC with fresh information based on the new impressions of how much we enjoyed the evening’s soup and pasta.

Shifting perception

A cube that seems to shift its spatial arrangement as you keep looking; the elegant silhouette of a pirouetting dancer, which starts to spin in the opposite direction the more you stare at it; an illustration that shows two profiles – or is it a vase? These optical illusions are examples of bistable visual perception. Beyond their entertaining aspect, they provide a way for scientists to explore the dynamics of human consciousness, and the neural regions involved in this process.

Ever Suddenly Gotten Lost in a Grocery Store? Here’s What It Means About Your Brain Health

Picture this: You’re walking around a grocery store you’ve shopped in a hundred times before, when all of a sudden you feel disoriented. You could’ve sworn the seafood section was in the back-right corner of the store, and you can’t remember where the pastries are at all. If this has ever happened to you, you might have wondered if it was just run-of-the-mill forgetfulness, or a sign of a larger issue. Good news: It may be nothing to worry about! According to a recent study, a sudden lapse like this could be due to a relatively normal brain response.

I won’t have what he’s having: The brain and socially motivated behavior

Aichi, Japan — How much we value an item is often related to what other people have. You might want the newest fashion, but not once everybody has it. Or, winning a free lunch at your favorite restaurant might not seem as great if the other person won a million dollars. Now, researchers in Japan have discovered a region of the brain that controls these kinds of behaviors in monkeys.

Our Brain When We’re in the Zone

W e have all experienced it before. You are heads-down, working on something (typically with some complexity), and we experience intense focus. We do not notice distractions, and (sometimes) we even lose track of time. While some may know this as being in the zone, brain researchers classify this as being in a flow state. So any time you reach a moment of peak enjoyment as you are doing a difficult task in which you are highly skilled, you are in a flow state. While researchers have known about flow states for some time, the actual mechanics of what happens in our brain during a flow state is less understood. We know that most of our tasks do not rely only on one brain region. Instead, it is a coordinated effort amongst multiple regions of the brain. So, how do our brains adapt or change while in a flow state? This is what researchers from UC Davis sought to explore.
