Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

885
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Dynamic Equilibrium

62.4K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

¹H NMR of Labile Protons: Temporal Resolution

Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum.
The –OH proton in alcohols typically appears in the range of δ 2 to 5 ppm but can vary depending on the specific...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

¹H NMR of Conformationally Flexible Molecules: Temporal Resolution

1.3K
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

Visual System01:26

Visual System

1.8K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Summary
This summary is machine-generated.

Attention levels decrease after an expected event, not before. This study on temporal attention reveals a pattern inconsistent with current theories, suggesting a subjective estimation of event probability influences attention dynamics.

Area of Science:

  • Cognitive Neuroscience
  • Psychology
  • Neuroscience

Background:

  • Temporal preparation of attention is crucial for efficient sensory processing of upcoming events.
  • Existing models of temporal attention, like hazard rate and stimulus-driven oscillations, do not fully explain observed dynamics.

Purpose of the Study:

  • To investigate the dynamic changes in attention levels around an expected event.
  • To compare empirical findings with predictions from existing temporal attention theories.

Main Methods:

  • Measuring contrast sensitivity to a target following a five-second temporal countdown cue.
  • Conducting control experiments to rule out biased time perception.
  • Utilizing a generative computational model to interpret results.

Main Results:

  • Attention levels remained stable before the expected event but decreased sharply afterward.
  • Attention increased up to 500ms before the event and then declined.
  • Findings contradicted predictions from hazard rate and stimulus-driven oscillation models.

Conclusions:

  • Observed attention patterns suggest temporal attention is influenced by subjective estimations of event probability and hazard rate.
  • Dynamic changes in attention are not solely explained by existing theoretical frameworks.
  • Future models of temporal attention should incorporate subjective probability assessments.
