Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transcranial stimulation methods for improving cognitive function after traumatic brain injury are non-specific and fail to target the disruption of synchronized activity across brain regions, leading to ineffective recovery of long-range communication and cognitive function.
Innovation Solution
A system that generates a customized stimulation pattern based on damaged white matter, using electrodes to synchronize neural activity during wakefulness and sleep, with the help of processors and memory storage for executable instructions, to activate electrodes in phase with natural brain oscillations and STAMP patterns for task learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-targeted transcranial stimulation is applied to globally increase synchrony, then overall brain synchrony is improved, but the specific disruption of long-range communication in TBI patients is not corrected
Solution Approach 1:
The patent applies local quality by transitioning from non-targeted global stimulation to targeted stimulation that specifically addresses damaged white matter regions. The system uses DTI data to identify specific damaged fiber tracts and places electrodes accordingly, so that stimulation is localized to regions where synchrony disruption occurs, rather than applying uniform stimulation across the entire brain.
Solution Approach 2:
The patent segments the brain stimulation approach by dividing the stimulation protocol into multiple electrode placements corresponding to different damaged white matter tracts. Each electrode pair targets a specific fiber tract (e.g., corticospinal, corticobulbar, corticopontine, corticorubral fibers), allowing independent optimization of synchrony restoration for each damaged pathway.
2Adaptability or versatility
If customized stimulation patterns are generated based on DTI data, then specificity to damaged white matter is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by performing DTI data acquisition and processing before the actual stimulation treatment. The system pre-processes the DTI data to identify damaged white matter tracts and generate customized electrode placement plans in advance, so that when treatment begins, the complex customization work is already complete, simplifying the treatment delivery process.
Solution Approach 2:
The patent uses DTI data as an intermediary that bridges the gap between individual patient anatomy and stimulation protocol generation. The DTI data serves as a mediator that translates structural damage information into actionable electrode placement instructions, automating the customization process and reducing manual system complexity.
3Reliability
If electrodes are activated in phase with natural brain oscillations, then synchrony of neural activity is improved, but precision of timing control is required
Solution Approach 1:
The patent applies feedback by continuously monitoring brain oscillations during stimulation and adjusting electrode activation timing accordingly. The system uses EEG or similar sensors to detect actual brain oscillation patterns and synchronizes stimulation pulses to these real-time oscillations, ensuring precise timing control that adapts to individual patient responses and maintains optimal synchrony enhancement.
