Summary
Selective stopping involves a nonselective pause process, delaying responses even when not intended to stop. This stopping-interference effect is not solely due to attentional capture, suggesting a broader inhibitory mechanism.
Area of Science:
- Neuroscience
- Cognitive Psychology
Background:
- Selective response inhibition is crucial for complex actions.
- Stopping-interference effects suggest nonselective inhibition during selective stopping.
Purpose of the Study:
- Investigate if nonselective response inhibition stems from a global pause or a specific cancel process.
- Differentiate between attentional capture and nonselective cancellation mechanisms.
Main Methods:
- Used a bimanual anticipatory response inhibition paradigm with selective stop/ignore signals.
- Recorded electroencephalography (EEG) for frontocentral and sensorimotor beta-bursts.
- Measured corticomotor excitability and intracortical inhibition using transcranial magnetic stimulation (TMS).
Main Results:
- Behavioral data showed response delays in the non-signaled hand during ignore and stop trials.
- The largest response delay occurred during selective stop trials, indicating stopping-interference exceeds attentional capture.
- EEG revealed stimulus-nonselective frontocentral beta-burst increases during stop/ignore trials.
Conclusions:
- Nonselective response inhibition during selective stopping is primarily driven by a nonselective pause process.
- The nonselective pause process does not fully explain the observed stopping-interference effect.
- Sensorimotor response inhibition signatures did not correlate with stopping-interference magnitude.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

01:20Desensitization and Tachyphylaxis
1.9K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

1.9K
Indirect-acting cholinergic agonists work by interacting with an enzyme called acetylcholinesterase (AChE) in the synaptic cleft. They can be reversible or irreversible inhibitors and have different effects on the enzyme.
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex,...

6.2K
G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...

01:25Dose-Response Relationship: Selectivity and Specificity
7.0K
Drugs exert their therapeutic effects by interacting with receptors, enzymes, or ion channels that are present throughout the human body. The strength and duration of the interaction between a drug and its target receptor are characterized by the selectivity and specificity of the drug. Selectivity refers to a drug's strong preference for its intended target over other targets. For instance, isoprenaline, a non-selective β-adrenergic agonist, interacts with both β1- and...

Bacterial growth is closely tied to nutrient availability, with cells proliferating exponentially under favorable conditions and entering a stationary phase when resources become scarce. This transition is mediated by a regulatory mechanism known as the stringent response, which allows bacteria to adapt to nutrient deprivation by modulating gene expression and metabolic activity.During nutrient scarcity, intracellular amino acid levels decline. It results in the accumulation of uncharged tRNAs...
