Exam, neural interfaces (Machine interfaces)

Question 1

In what way is the event-related resynchronization/Synchroniation (ERD/ERS) metric based on?

Answer 1

The power of the EEG signal is increasing the synchronization of the underlying oscillatory sources

Question 2

What is the analysis of the heart rate variability (HRV) used to quantify?

Answer 2

The heart rate variability (HRV) is used to quantify the activity of the autonomous nervous system (ANS)

Question 3

What is the Phase Locking Value (PLV) aiming to compare?

Answer 3

The phase Locking Value (PLV) aims at comparing the phase of two periodic waved

Question 4

In what way is the Phasing Locking Factor field (PLFf) aiming to quantify the synchronization level?

Answer 4

The PLFf aims at quantifying the synchronization level in a continuous oscillatory field

Question 5

What is the Local field potential (LFP)?

Answer 5

The local field potential is the potential in the extracellular space around the neurons

Question 6

What is the case of the periodic signal e(t)=sin(2pift+theta)?

Answer 6

The phase is 2pift + theta

Question 7

What system does the Heart rate variability (HRV) reflect?

Answer 7

The heart rate variability reflects the activity of the autonomic nervous system

Question 8

What event is observed during neural activity?

Answer 8

Desynchronization of neurons(ERD)
