With functional magnetic resonance imaging (fMRI), we identify an occipito-temporal region activated by cyclopean stereomotion-in-depth stimulation, centered anterior to the human motion complex hMT+.
Stimulus-induced LFP and responses were calculated as the mean response for 10 stimulations in Experiment 1 (i.e. at each cortical depth, stimulus intensity, or injection condition) or 100 stimulations in Experiment 2 (i.e. at each cortical depth).
Intracortical microstimulation is one of the most common techniques to causally interfere with neuronal processing, but neuronal recordings spanning the whole cortical depth during stimulation are exceptionally rare.
Depth of stimulation is limited with currently approved figure-eight coils and larger coils capable of deeper penetration may be associated with loss of stimulation focality and undesired recruitment of motor cortex.
It should be remembered that this increased depth of stimulation is likely to come at the expense of focality [5].
The depth of stimulation varied from 0 to 9 mm below the epicardial surface in right ventricle and 1 to 15 mm in left ventricle.
The double-cone coil is specifically designed to achieve greater depth of stimulation, making it an appropriate tool to target the deep lying cerebellum and its motor representations.
Then, a summary of recordings was evaluated in order to decide in which channels and at what depths test stimulation should be performed.
The projects are classified by country, reservoir type, depth, reservoir temperature, stimulation methods, associated seismicity, plant capacity and current status.
For both periodic and single sources, the accuracy in the image plane ΔR was ~3.3 mm and did not depend on stimulation depth.
However, closer examination within this small sample suggests a possible relationship between stimulation depth and percentage improvement in the Gait and Falls questionnaire with the best outcome being achieved when stimulation was applied at the level of maximal alpha activity (Fig. 4B).
