Brain Dynamics Toolbox (Version 2019a)

Changes
This release includes new example scripts for the Morris-Lecar neuron and Tsodyk's (1999) inhibition-stabilised neuron. As well as examples of Partial Differential Equations such as the scalar wave equations and the Fisher-Kolmogorov equations. The damped-and-driven pendulum is included too. The Breakspear-Terry-Friston (2003) model has been revamped. New command-line tools (bdSetPar, bdSetVar, bdSetLag, bdGetPar, bdGetVar, bdGetLag) make it easier to manipulate models in user-defined scripts. The nullclines in the Phase-Portrait have been made smoother. Trajectory end-points in most panels are now marked with a dark filled circle. The correlation panel has an improved colormap.

Brain Dynamics Toolbox (Version 2018b)

This release includes new example scripts for the Hodgkin-Huxley model of the action potential, the Wilson- Cowan model of excitatory-inhibitory dynamics, the Epileptor model of seizure dynamics and the Haemodynamic model of the BOLD response. It also includes new display panels for plotting state variables that have two spatial dimensions (bdSpace2D) and for computing the BOLD response for any state variable (bdBoldHRF). The Auxiliary panel (bdAuxiliary) panel has been improved to allow user-data to be accessible to the workspace. New functions bdSetValues and bdEvolve have been added to the command-line tools. The bdLoadMatrix function has been removed. The HALT, EVOLVE and PERTURB graphical buttons can now be controlled from the workspace interface. Their initial states can also be specified in the system structure. A RUN button has been added to the graphical interface. It replaces the RAND button when the EVOLVE mode is active. A matrix transpose bug in the BTF2003/SDE/DDE models was fixed. A drawing bug in the phase-portrait 3D View menu was fixed. Chapters 5 and 6 of the Handbook were revised substantially.

Brain Dynamics Toolbox (version 2018a)

Changes
This is a major upgrade to the toolbox. The graphical user interface has been redesigned substantially. It now includes sliders and buttons for manipulating parameter values more easily. The plotting limits for each variable/parameter are now specified in the control panel itself. A time slider has also been added for managing transient dynamics. Initial conditions can now be automatically perturbed and/or evolved over successive simulation runs. The look and feel of the display panels have been redesigned. Individual panels can now be exported as Matlab figures. Nulllclines/planes have been added to the Phase Portrait. Three dimensional surface plots have been added to the space-time panel. Font sizes in the Equation panel can now be altered. A new panel has been added for bifurcation plots. A new panel has been added for user-defined auxiliary plotting functions. There is a new toolbar which is dedicated to the solver. The fidelity of the progress counter has been improved too. The previous dependencies on the Matlab Signal Processing and Statistics and Machine Learning toolboxes have been removed.

Brain Dynamics Toolbox (version 2017b)

Changes
This version of the Brain Dynamics Toolbox includes major new features that improve the accessibility of GUI parameters and variables to the Matlab workspace. System parameters can now be manipulated directly from the workspace via the par property of the bdGUI class. Likewise, solution variables can be accessed via the var property. Solution variables and display panel outputs can also be saved to mat files via the System-Save menu. Other changes include three new panels and six new models. See the Release Notes for details.

Brain Dynamics Toolbox (version 2017a)

Changes
This version is a substantial reorganisation of the code base. Major new features include: (1) Dynamic loading of GUI plot panels; (2) Direct access to solver output and panel objects via GUI properties; (3) Revised format for defining system parameters and variables; (4) Improved validation of system structures; (5) Improved Time and Phase portraits; (6) Revised example models. This version is not backwards-compatible with version 2016a. See the Release Notes for details on how to migrate existing code.
