Summary
Researchers used decoded neurofeedback (DecNef) to show that the frontoparietal network influences how confident people feel about their perceptions. This suggests a specific brain region is key for metacognition, or thinking about thinking.
Area of Science:
- Neuroscience
- Cognitive Science
- Psychology
Background:
- Humans possess metacognitive abilities, allowing them to assess confidence in their own perceptions.
- The neural underpinnings of metacognition, particularly the brain mechanisms for subjective confidence, remain an active area of research.
Purpose of the Study:
- To investigate the neural mechanisms of perceptual confidence.
- To determine if the frontoparietal network plays a distinct role in metacognition.
Main Methods:
- Utilized decoded neurofeedback (DecNef) to manipulate neural activity.
- Focused on altering multivoxel activation patterns within the frontoparietal network.
- Assessed the impact of neural manipulation on perceptual confidence and performance.
Main Results:
- Successfully modulated subjective perceptual confidence using DecNef.
- Demonstrated that manipulating the frontoparietal network affects confidence without altering perceptual performance.
- Provided evidence for a dissociation between confidence and performance.
Conclusions:
- The frontoparietal network is critically involved in regulating perceptual confidence.
- This network plays a distinct role in metacognitive functions, separate from direct perceptual processing.
- Findings support a specialized neural basis for metacognition.

Metacognition
868
Metacognition is a conscious process where individuals are aware of their cognitive and executive processes, such as planning before solving a problem or self-monitoring during reading. For instance, a writer may need help with composing a piece. The situation involves a writer who is working on a piece of writing, but while doing so, they realize that something is missing. They notice that their characters lack depth or details. This realization occurs because the writer is reflecting on their...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
934
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

tRNA Activation
23.2K
Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Histone Modification
16.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

From DNA to Protein
22.6K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Internal Receptors
74.8K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
