Space and Time of Cortical Activity Activity can be measured by fMRI (or PET) on a time scale of seconds, by EEG (or MEG) on a time scale of a small fraction of a second, and by microelectrodes on a time scale of milliseconds or less. A single neuron can be part of different processes at different times. It remains unclear how fast a neuron can switch its functional properties. If such switching can be made on a ms time scale, fast and efficient computations can be made. We show that the temporal precision of cortical neurons can be better than 1 ms. |
