Summary
Electrode reconstruction aids deep brain stimulation (DBS) contact selection for Parkinson disease. Neuroanatomic parameters predict optimal contacts, improving efficiency and reducing clinical time.
Area of Science:
- Neurosurgery
- Neurology
- Medical Imaging
Background:
- Deep brain stimulation (DBS) contact selection is time-consuming, especially with complex leads.
- Current methods involve testing contacts individually, posing clinical challenges.
Purpose of the Study:
- To guide clinicians in selecting optimal DBS contacts using neuroanatomic information.
- To leverage electrode reconstruction for improved contact selection efficiency.
Main Methods:
- Analyzed 33 Parkinson disease patients undergoing subthalamic nucleus (STN) DBS.
- Reconstructed electrodes and estimated Volume of Tissue Activated (VTA) for each contact.
- Calculated 6 neuroanatomic parameters including distances to STN/M-STN and fiber tract overlap.
Main Results:
- All 6 neuroanatomic parameters showed significant differences between optimal and non-optimal contacts.
- A generalized linear model predicted optimal contact selection with 72.7% accuracy.
- Electrode reconstruction combined with neuroanatomic parameters enhances prediction.
Conclusions:
- Electrode reconstruction is a valuable tool for optimizing DBS contact selection.
- This approach can significantly improve the efficiency of the clinical contact selection process.
- Neuroanatomic guidance enhances precision in DBS lead placement and programming.

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

01:19Contact-dependent Signaling
46.9K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

01:32What is Natural Selection?
128.8K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...
