While analog filters always create phase distortion, both the critically damped and Butterworth filters can be modified to become zero-lag filters when the data are processed in both the forward and reverse directions.
Information processed in the perirhinal cortex is forwarded to the entorhinal cortex, which presumably integrates it with visuospatial information from the parahippocampal cortex and higher-order information from other association cortices (Insausti et al., 1987; Suzuki and Amaral, 1994 b ; Canto et al., 2008), and transmits its output to the hippocampus (Witter and Amaral, 1991).
Low-level facial feature information might be processed in the OFA and then fed-forward into dorsal and ventral pathways (Haxby et al. 2000).
Sequencing was processed always in the forward and reverse directions using software Sequencing Analysis, MatchTools and Navigator (MatchTools Allele Identification package, Applied Biosystems, Foster City, CA, USA).
Thus, dynamic processes in the forward step were directly visualized at high spatial resolution.
On days when the process moves in the forward direction, the euro is bid up, the yen is bid down, and stocks in the U.S., Europe and Australia are bid up.
The pruning process to make computation efficient is done in the forward process only, by using the same process described in the previous section.
In addition, in the presence of a membrane potential, the activation process is strongly favored in the forward direction.
