Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

8.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Cooperative Binding of Transcription Regulators

7.4K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Functions of Connective Tissues

17.2K
Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

Summary
This summary is machine-generated.

Negative social feedback impairs cooperative action by decreasing cognitive performance and altering brain connectivity. This suggests that negative reinforcement shifts brain activity towards individual strategies, reducing effective joint action.

Area of Science:

  • Social Neuroscience
  • Cognitive Neuroscience
  • Neuroimaging

Background:

  • Understanding functional connectivity during cooperative actions is crucial in social neuroscience.
  • The impact of negative social feedback on cooperative capabilities remains largely unexplored.

Purpose of the Study:

  • To investigate the effects of negative social feedback on cognitive performance and neural activation during joint actions.
  • To analyze changes in intra- and inter-brain connectivity following negative social feedback.

Main Methods:

  • Functional near-infrared spectroscopy (fNIRS) was used to record prefrontal neural activation during a cooperative task.
  • Participants received negative feedback after joint actions, and performance metrics (error rates, response times) were measured.
  • Intra- and inter-brain connectivity indices, including the ConIndex, were computed.

Main Results:

  • Negative social feedback decreased cognitive performance and modulated neural activity.
  • Inter-brain connectivity decreased, while intra-brain connectivity increased after negative feedback.
  • Pre-feedback cooperative tasks enhanced brain-to-brain coupling in the dorsolateral prefrontal cortex (DLPFC).

Conclusions:

  • Negative social reinforcement negatively impacts cooperative action effectiveness and brain connectivity patterns.
  • Reduced inter-brain connectivity correlates with poorer cognitive performance, indicating a shift towards individualistic neural strategies.
  • Findings contribute to understanding neural mechanisms underlying cooperation under social feedback conditions.
