Importantly, the spike patterns do not need to repeat exactly: it also works when only a firing probability pattern repeats, providing this profile has narrow (10-20ms) temporal peaks. Brain oscillations may help in getting the required temporal precision, in particular when dealing with slowly changing stimuli ... 11:00 - 12:00 Theory Weekly Seminar (TWS) Quantum effects of the fields in Black Hole physics School PARTICLES AND ACCELERATORS Larak Seminar Room ... |
