Slowing of EEG, disappearance of alpha-waves, slow eye rolling

Describe sleep stage N2

Sleep spindles, K-complexes

Describe sleep stage REM-sleep

EEG is like when you are awake, muscle atonia

Indicate whether these neuromodulators go up or down during sleep:
1. Acetylcholine
2. Noradrenaline/serotonine
3. Cortisol

1. Up
2. Down.
3. Up

Which sleep is important for skill learning?

REM sleep

Grid cells play a role in?

Firing on certain locations. They form some kind of grid. They are also important for replay.

In which sleep is targeted memory activation effective?

Light (N2) and deep sleep (SWS).

Can we use TMR to induce memory enhancement?

Nahhh, not really. Would be so much fuss about so little achievement.

Does sleep change after studying?

No, sleep is found to be a pretty robust process.

What does targeted memory reactivation?

It manipulates (to a certain extent) replay.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
