ModelDB: Temporal and spatial characteristics of vibrissa responses to motor commands (Simony et al. 2010)

Temporal and spatial characteristics of vibrissa responses to motor commands (Simony et al. 2010)

Accession: 127512

"A mechanistic description of the generation of whisker movements is essential for understanding the control of whisking and vibrissal active touch. We explore how facial-motoneuron spikes are translated, via an intrinsic muscle, to whisker movements. This is achieved by constructing, simulating, and analyzing a computational, biomechanical model of the motor plant, and by measuring spiking to movement transformations at small and large angles using high-precision whisker tracking in vivo. ... The model provides a direct translation from motoneuron spikes to whisker movements and can serve as a building block in closed-loop motor–sensory models of active touch."

This program simulates the transformation from motoneuron spikes to
whisking rotation angle(theta) and to center of mass translations, x
and y.  If you are using this code, please cite the above the paper.


Simulation files:

test_motor_plant.m : run this file in order to simulate the plant. the
                     parameters set (small or large) should be enable
                     in the code.
motor_plant_parameters_small_angles.m : parameters set for small whisker angles
motor_plant_parameters_large_angles.m : parameters set for large whisker angles
motor_plant.m                         : intialize all data structures
motor_plant_ode.m                     : ODE file 

Output1: currently it reproduces Fig 4B (model)


for 2 spikes with ISI:17msec (together with x and y ) make sure that
"motor_plant_parameters_small_angles" in "test_motor_plant.m" is
enabled (uncommented at the front of the script;  this is default)

Output2: it reproduces Fig 5C (model), for 3 spikes with ISI:15msec
(together with x and y ) make sure that
"motor_plant_parameters_large_angles" in "test_motor_plant.m" is
enabled.
