ABSTRACT
The timing of brain events can be assessed in relation to these clocks; however, we need to consider the encoding of temporal information by the brain, not the time course of neural activity in the brain, to relate neural processing and the perceived time course of external events. However, the flow of neural events, even if it matched the time course of events in the external world, carries only implicit information about temporal relationships, such as whether one event occurs before another or what the duration of an event might be. The Fourier transform expresses a time-windowed signal as a sum of sine and cosine functions of different magnitudes and frequency. One consequence of the action of a temporal filter in integrating information over a period of past time is that the neural representation or neural image of the external world is delayed by around 80 ms relative to external events.
