Multiple Particle Tracking Data from Neonatal Organotypic Rat Brain Slices

The data includes statistical features generated from raw multiple particle tracking data from videos collected during three independent experiments: (1) 5 different brain regions, (2) 3 different treatment conditions in the brain, and (3) 5 different brain ages. 

Feature
Model Abbreviation
Description

alpha
alpha
Exponent of the anomalous diffusion equation.

Effective diffusion coefficient
D_fit
Coefficient of the anomalous diffusion equation

Kurtosis
kurtosis
The fourth moment of the projected positions on the dominant eigenvector of the radius gyration tensor (T).

Asymmetry1
asymmetry1
Characterizes the asymmetry of the trajectory. Asymmetry1 equals 0 for circularly symmetric trajectories and 1 for linear trajectories.

Asymmetry2
asymmetry2
The ratio of the smaller to larger principal radius of gyration.

Asymmetry3
asymmetry3
An asymmetry feature that accounts for non-cylindrically symmetric point distributions.

Aspect ratio
AR
The ratio of the kong and short side of the trajectory's minimum bounding rectangle. Perfectly symmetric trajectories have an aspect ratio of 1, and aspect ratio increases as trajectories become more elongated. 

Elongation
elongation
An estimation of amount of extension of the trajectory from its centroid. 

Boundedness
boundedness
Boundedness quantifies how much a particle with diffusion coefficient Deff is restricted by a circular confinement of radius r when diffusing for a period of time \(N\Delta t \)

Fractal Dimension
fractal_dim
Fractal dimension is a measure of how "complicated" a self similar figure is. 

Trappedness
trappedness
The probability (\(\textit{P}_{\textit{t}} \)) that a particle with duffusion coefficient Deff is trapped in a region (r0) for a period of time \(N\Delta t \). 

Efficiency
efficiency
The ratio of the squared net displacement to the sum of step lengths. 

Straightness
straightness
The ratio of the net displacement to the sum of step lengths. 

MSD Ratio
MSD_ratio
MSD ratio characterizes the shape of the MSD curve. For Brownian motion, it is 0; For restricted motion it is < 0; For directed motion it is > 0. 

Frames
frames
The total number of frames the trajectory spans. 

Effective Diffusion Coefficient 1
Deff1
Effective diffusion coefficient at 0.33 s.

Effective Diffusion Coefficient 2
Deff2
Effective diffusion coefficient at 3.3s. 

Mean values were calculated based on surrounding datapoints for alpha, D_fit, kurtosis, asymmetry1, asymmetry2, asymmetry3, AR, elongation, boundedness, fractal_dim, trappedness, efficiency, straightness, MSD_ratio, Deff2, and Deff2.
