15 Questions
What does the 'optimal subspace hypothesis' assume about movement production (Brown & Teskey, 2014)?
It is dependent on the initial state of firing rates.
In the context of the optimal subspace hypothesis, what does the 'optimal subregion' refer to (Brown & Teskey, 2014)?
A subset of population firing rates suitable for accurate movement.
How does motor preparation differ between the 'optimal subspace hypothesis' and the 'rise-to-threshold model' (Brown & Teskey, 2014)?
In the hypothesis, firing rates remain within an optimal region, whereas in the model, a threshold triggers movement.
What is the key difference in firing rate concentration between the 'optimal subspace hypothesis' and other models during delay periods (Brown & Teskey, 2014)?
Concentrated within a subregion of accessible space specific to each planned movement.
What is preserved by keeping firing rates within the optimal subregion while awaiting movement initiation (Brown & Teskey, 2014)?
An appropriately prepared state for movement execution.
Which movement type was given a score of 0.5 in the study mentioned (Kida et al., 2016)?
Digit flexion
What does the '0' score represent for movements in the study (Kida et al., 2016)?
Normal movements
Which cortical area showed a size of 0.575 mm² in the forelimb motor map topography (Kida et al., 2016)?
Simple Digit flexion
What are the AP coordinates for the Supination movement representation (Kida et al., 2016)?
2.326 ± 0.089 mm
In the study, what type of movements were chosen to provide effective deactivation of the CFA or RFA (Kida et al., 2016)?
Complex movements
Which type of stimulation is far more effective in M1 and M1 originating fibers (Jahangiri et al., 2022)?
High-frequency (HF) stimulation
Why might negative mapping be sought in some cases during brain stimulation (Jahangiri et al., 2022)?
To avoid the brain's motor area
How does Taniguchi's short-train method differ from the Penfield method in terms of monitoring during tumor removal (Jahangiri et al., 2022)?
Taniguchi's method provides more continuous monitoring
What does the tangential-radial triphasic (TRT) cortical model aim to reduce (Jahangiri et al., 2022)?
The need for higher stimulation parameters
How does the Penfield method differ from Taniguchi's short-train method in analyzing factors like latency and duration (Jahangiri et al., 2022)?
Penfield method provides better analysis due to summative excitation
