0-81 |
DRI_Challenge |
denotes |
Three-dimensional tuning profile of motor cortical activity during arm movements. |
| T2 |
82-185 |
DRI_Outcome |
denotes |
The neural firing activity in the primary motor cortex was modulated to the direction of hand movement. |
| T3 |
186-378 |
DRI_Background |
denotes |
In contradiction to previous reports, a recent study found a non-uniform distribution of preferred directions of neurons while monkeys made center-out reaching movements in a horizontal plane. |
| T4 |
379-728 |
DRI_Approach |
denotes |
To re-examine the distribution of preferred directions in three-dimensional space, we recorded the activity of 117 arm-related neurons in the primary motor cortex and electromyographic signals of shoulder and upper arm muscles of a monkey while it performed center-out reaching movements towards 26 target points placed on a sphere-shaped workspace. |
| T5 |
729-881 |
DRI_Approach |
denotes |
We found that the distribution of preferred directions of neurons was non-uniform and that it was correlated to muscle activity and arm joint rotations. |
