Acids and bases are substances capable of donating protons (H+) and hydroxide ions (OH-), respectively. They are two extremes that describe chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. A substance that is neither acidic nor basic is neutral. The values of proton concentration ([H+]) for most solutions are inconveniently small and difficult to compare so that a more practical...

Chromatin Structure Regulates pre-mRNA Processing

8.1K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

In order for recognition of a certain stimulus to take place, visual attention needs to be directed towards said stimulus. To the earliest parts of the visual system, objects are not objects, they are collections of visual features-lines, corners, changes in texture, color, and light. Attention is the resource that is necessary for later processing in order to recognize what a given bundle of features adds up to. This makes...

Subliminal Perception01:15

Subliminal Perception

764
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Factors Affecting Perception01:25

Factors Affecting Perception

2.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Area of Science:

  • Cognitive Neuroscience
  • Auditory Perception
  • Music Cognition

Background:

  • Meter perception research often uses surface-based methods, potentially confounding meter and rhythm.
  • Previous findings suggest different meter dimensions may have varying attention requirements.

Purpose of the Study:

  • To investigate attention effects on structural meter processing using electroencephalography (EEG).
  • To examine the two dimensions of meter perception: beat hierarchy and cycle-length regularity.

Main Methods:

  • EEG recording during structural meter processing tasks.
  • Analysis of event-related potentials (ERPs) to assess attention effects.
  • Distinguishing between hierarchy and cycle-length dimensions of meter.

Main Results:

  • Cycle-length violations elicited pre-attentive responses (late ERPs, 300-600 ms).
  • Hierarchy violations yielded inconclusive results regarding attention.
  • Findings suggest deep, structural meter processing can be pre-attentive.

Conclusions:

  • Meter perception, specifically cycle-length regularity, can be processed pre-attentively.
  • Highlights the significance of pre-attentive processing in auditory meter perception.
  • Proposes a dissociation between surface-based and structure-based meter processing.
