Also, a sensitive dependence on the initial conditions of two trajectories for y-coordinate of the model (3) is plotted in Figure 6(b).
Patients were categorized into one of four trajectories based on their SAHD scores at both time points: low (low DHD at T1 and T2), rising (low DHD at T1 and high DHD at T2), falling (high DHD at T1 and low DHD at T2) and high (high DHD at T1 and T2).
The measurement campaign of thirteen trajectories on the third and fifth floor in congress center 'Lamot' has been considered as a third validation case, and the measurement campaign of seventeen trajectories on three floors of arts center 'Vooruit' as a fourth validation case.
The measurement campaign of twelve trajectories on the ground floor in 'De Vijvers', a retirement home, has been considered as a second validation case.
A cell was considered bi-directional if it was location-responsive on the two opposite trajectories and its firing rate curves on the two trajectories had a cross-correlogram with a significant peak location within [−50, 50] cm (Pearson's p < 0.00098, adjusted down from 0.05 to account for multiple tests at all 51 position lags).
(A, B ) Histograms of the number of firing fields for V1 (A ) and CA1 (B ) cells on the two trajectories of the track with opposite running directions.
An example of CA1 cell with retrospective firing is shown in Figure 4B, with a significant peak at a negative position lag (−18 cm, p < 0.0001) in the cross-correlogram between its firing rate curves on the two trajectories.
An example of V1 cell with prospective firing is shown in Figure 4A, which was quantified by a significant peak at a positive position lag (36 cm, p < 0.0001, Pearson's r) in the cross-correlogram between the cell's firing rate curves on the two trajectories.
In this section, we report results on analyzing the two trajectories of the small synthetic protein BBA5 and the five trajectories of another small protein GSGS.
To understand whether this peculiar feature of Tau neurons requires spatial experience, we also recorded CA1 neurons while mice explored a novel open box for one to two sessions and then ran back and forth (two trajectories) on a novel track for one to two sessions in a novel room.
