Human Memory Retrieval is predicted by Theta Frequency Phase locking of Single Neurons.
Based on Rutishauser et al. Nature 464 903- 7
Hypothesis
During memory retrieval a substantial fraction of neurons produce spikes which are phase-locked with the 3 – 8 Hz range of the Local Field Potential.

Can an increase of phase-locked spikes during learning predict an increase in memory retrieval strength?
Method I
A memory test with two parts was devised.

Learning: Patients were given a set of 100 previously unseen images.
