Mental State Replication via Neural Signal Intermediary Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to accurately and precisely replicate complex mental states in humans or animals due to limitations in interpreting neural correlates of mental states, particularly due to the filtering effects of the skull and cerebrospinal fluid on brain signals, leading to loss of spatial resolution and amplitude of electrical signals.
Innovation Solution
The method involves capturing neural correlates of a desired mental state through brain activity patterns like EEG or MEG signals from a donor subject and using these patterns to control stimulation in a recipient subject, employing raw brain activity data for filtering and transformation into suitable stimulation forms, such as sensory or transcranial stimulation, to induce the same mental state, with adaptive feedback for optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If EEG or MEG signals are captured through the skull and cerebrospinal fluid, then brain activity patterns can be obtained, but spatial resolution and amplitude of signals are lost due to filtering effects
Solution Approach 1:
The patent uses an intermediary system consisting of a donor subject, signal capture apparatus, computer-based processing system, and recipient subject. The raw brain activity data from the donor is processed through multiple intermediary steps including filtering, transformation, and conversion into stimulation forms before being applied to the recipient. This intermediary processing chain allows the system to overcome the filtering effects of the skull and cerebrospinal fluid by reconstructing and amplifying the neural correlates outside the body.
Solution Approach 2:
The patent replaces direct mechanical/electrical measurement through the skull with a computational approach. Instead of trying to physically penetrate the skull and cerebrospinal fluid barriers to measure brain activity, the system captures external signals and uses computer-based processing to reconstruct the neural correlates. This substitution of mechanical measurement with computational reconstruction preserves spatial resolution and signal amplitude that would otherwise be lost.
2Adaptability or versatility
If complex mental states are attempted to be replicated, then the full range of neural correlates must be captured, but current technology cannot accurately encode or characterize the full range of mental states
Solution Approach 1:
The patent employs dynamic, adaptive processing of brain activity patterns. The system continuously monitors and adjusts the transformation of neural correlates from the donor to the recipient, allowing it to handle the complex, changing nature of mental states. The computer-based processing system can adapt to different mental states and adjust the stimulation parameters in real-time, enabling the replication of a full range of mental states with improving accuracy over time.
Solution Approach 2:
The system incorporates feedback mechanisms where the recipient's brain activity is monitored and used to adjust the stimulation parameters. This feedback loop allows the system to refine its encoding and characterization of mental states, progressively improving measurement precision as it learns from the recipient's neural responses. The feedback enables accurate replication of complex mental states by continuously optimizing the transformation process.
3Loss of information
If raw brain activity data is used for stimulation, then the full neural information is preserved, but the data must be filtered and transformed into suitable stimulation forms
Solution Approach 1:
The computer-based processing system serves multiple functions: it filters raw brain activity data, transforms neural correlates into stimulation forms, adjusts stimulation parameters, and monitors recipient responses. This multi-functional system handles the entire processing chain from raw data to effective stimulation, managing the complexity through integration. The universal processing platform can adapt to different types of brain activity data and transform them into appropriate stimulation forms for various mental states.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively replicates the mental state in the recipient subject by respecting subtle brain activity patterns, even if not fully understood, ensuring resonance with the donor's neural frequencies, thus achieving the desired mental state with potential applications in mental state modification and synchronization.
Implementation Method 1
The brain communicates with the body through the spinal cord and twelve pairs of cranial nerves. Ten of the twelve pairs of cranial nerves that control hearing, eye movement, facial sensations, taste, swallowing and movement of the face, neck, shoulder and tongue muscles originate in the brainstem.
Implementation Method 2
The skull therefore imposes a barrier to electrical access to the brain functions, and in a healthy human, breaching the dura to access the brain is highly disfavored. The result is that electrical readings of brain activity are filtered by the dura, the cerebrospinal fluid, the skull, the scalp, skin appendages (e.g., hair), resulting in a loss of potential spatial resolution and amplitude of signals emanating from the brain.
