Optimal Arousal Theory01:23

Optimal Arousal Theory

The optimal arousal theory suggests that performance is maximized when an individual experiences a moderate level of arousal. This theory is closely tied to the Yerkes-Dodson law, which illustrates an inverted U-shaped relationship between arousal and performance. The law, formulated by psychologists Robert Yerkes and John Dodson, implies an ideal arousal level for optimal performance, and deviations from this level can lead to declines in effectiveness.

Association Areas of the Cortex01:21

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
Brain Waves01:23

Brain Waves

Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Oscillations In An LC Circuit01:30

Oscillations In An LC Circuit

An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by
Oscillations about an Equilibrium Position01:04

Oscillations about an Equilibrium Position

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so because...

Summary
This summary is machine-generated.

Visual alpha power and default mode network (DMN) activity correlate positively when eyes are open, suggesting a mechanism for gating external visual input during rest. No correlation was found with eyes closed.

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience
  • Psychophysiology

Background:

  • Alpha oscillations (8-12 Hz) decrease with attention but their fluctuations impact visual processing and performance.
  • The default mode network (DMN) typically deactivates during attention-demanding tasks; insufficient deactivation leads to attentional lapses.
  • Previous observations suggest a potential positive correlation between visual alpha power and DMN activity.

Purpose of the Study:

  • To investigate the correlation between visual alpha power and DMN activity during resting states.
  • To determine if this correlation differs between eyes-closed and eyes-open resting conditions.

Main Methods:

  • Simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) were recorded from healthy participants.
  • Resting-state data were collected under both eyes-closed and eyes-open conditions.
  • Short-time visual alpha power was extracted and correlated with blood-oxygen-level-dependent (BOLD) signals from the DMN after convolution with a hemodynamic response function (HRF).

Main Results:

  • A significant positive correlation was found between visual alpha power and DMN BOLD activity exclusively in the eyes-open resting condition.
  • No significant correlation between visual alpha power and DMN BOLD activity was observed in the eyes-closed resting condition.

Conclusions:

  • During eyes-open rest, DMN activity may modulate visual cortical excitability to gate external visual input, prioritizing internal processing.
  • The absence of correlation in the eyes-closed condition suggests this gating mechanism is less critical without external visual stimuli.
