Local Attraction01:22

Local Attraction

370
Local attraction refers to disturbances in compass readings caused by magnetic influences from nearby objects such as metal fences, buried pipes, vehicles, buildings, power lines, or natural iron ore deposits. Small items like wristwatches, steel tools, or belt buckles can also interfere with the compass by creating local magnetic fields that distort the Earth's natural magnetic field. These distortions lead to inaccurate readings, posing navigation and land surveying challenges.Local...

Local Anesthetics: Pharmacokinetics01:13

Local Anesthetics: Pharmacokinetics

1.2K
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Local Anesthetics: Mechanism of Action01:23

Local Anesthetics: Mechanism of Action

3.3K
Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

Nuclear Localization Signals and Import01:46

Nuclear Localization Signals and Import

7.7K
Proteins targeted to the nucleus carry short stretches of amino acid sequences called the nuclear localization signal or NLS. Classical nuclear localization signals are of two types: monopartite and bipartite NLS. Monopartite classical NLS (cNLS) consists of a single cluster of 4-8 amino acids. Bipartite cNLS consists of two clusters of  2-3 amino acids and a 9-12 residue long proline-rich linker bridging the two clusters. Signal clusters are rich in positively charged amino acids such as...

Absolute and Local Extreme Values01:22

Absolute and Local Extreme Values

58
The highest and lowest values of a function, relative to a reference axis, are known as extreme values. These include absolute maximum and absolute minimum values, which represent the highest and lowest points the function reaches across its entire domain. Within a restricted portion of the function, the highest and lowest values are referred to as local maximum and local minimum values, respectively.Periodic functions, such as sine and cosine, show extreme values at infinitely many points due...

Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

779
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Summary
This summary is machine-generated.

Object localization from brief glimpses is surprisingly accurate, even with limited attention. This directional information is crucial for 3D perception and egocentric distance estimation.

Area of Science:

  • Cognitive Psychology
  • Visual Perception
  • Neuroscience

Background:

  • Understanding object localization is key, especially when time and attention are limited.
  • Real-world scenarios often require reacting to briefly glimpsed objects outside the focus of attention.

Purpose of the Study:

  • To investigate the impact of attentional constraints on 2D (directional) object localization.
  • To determine how brief target durations and cue validity affect localization accuracy.

Main Methods:

  • Two experiments used briefly presented asterisk targets (34-150 ms) above or below a fixation point.
  • Cues directed attention toward or away from the target.
  • Participants reported target detection and then localized the target using a mouse, with undetected trials removed.

Main Results:

  • Longer target exposure durations generally improved localization accuracy.
  • Cue validity had minimal impact on localization sensitivity, bias, or precision.
  • Very brief target durations with invalid cues led to a slight increase in foveal bias.

Conclusions:

  • Directional object location can be extracted effectively from brief glimpses, even with reduced attention.
  • This directional information is fundamental for 3D object localization and egocentric distance perception.
  • Egocentric distance perception appears robust to reduced attention when relying on angular declination.
