Brain Stimulation Review

Vural et al (2024) found that tDCS had different effects on brain metabolites in women compared to men.

• True
• False

Which statement best describes the process in an open loop system?

• It is adjusted based on output.
• It is initiated by feedback.
• It follows a preset sequence.
• It self-corrects during operation.

As the attentional demand of a task is increased, the dichotomy (activity increasing, activity decreasing) becomes less pronounced.

• True
• False

What do low-frequency oscillations represent?

• Activity at a smaller spatiotemporal scale
• Activity at a larger spatiotemporal scale
• Activity at a medium spatiotemporal scale
• Activity at an undefined spatiotemporal scale

Anticorrelations may be as important as correlations in brain organization.

• True
• False

Vural et al (2024) found that tDCS had no effect on the levels of brain metabolites in the prefrontal cortex.

• True
• False

Dockery et al. (2009) found that cathodal tDCS applied during the early learning phase led to the greatest improvements in planning ability.

• True
• False

What was the highest single electrode intensity Jamal et al. (2023) tested to be safe in older adults?

• 1 mA
• 2 mA
• 4 mA
• 10 mA

According to the TED Talk we watched in class, why did OpenBCI integrate additional sensors beyond EEG?

• To eliminate the need for computers
• To enhance brain data with context
• To focus solely on muscle activity
• To reduce production costs

How might consumer neurotech devices impact mental health treatment?

• By replacing traditional therapy
• By offering instant cures for all mental disorders
• By providing new methods for brain health monitoring
• By eliminating the need for medication
