Neural Engineering
- Artificial Retina
- Current generation: Very low resolution.
- "Learning to see" period.
- Epilepsy - Implantable Electrodes, Brain Cooling, Drug Delivery
- Implantable Devices Could Detect and Halt Epileptic Seizures - Scientific American
- Closed Loop Devices:
- Idea: Detecting seizure onsets and stopping them.
- Implantable Electrodes
- Brain Cooling
- Detecting temperature (associated with seizures) and controlling
- Drug Delivery
- Closed loop
- Continuous, at regular intervals
- Challenges for Closed Loop Devices:
- False positives: Detecting normal activities as seizures.
- Open loop devices
- VNS - Vagus Nerve Stimulation (from 1997)
- Deep brain stimulation
- Some people have too many seizures; stopping some would be considered as progress.
- Second generation Closed Loop Devices
- Not just detecting onset of seizures; rather predicting seizures before they even start.
- Body Amputation
- Cochlear Implant
- Brain Computer Interfacing
- Tom Mitchell & others applying Machine Learning Techniques to find correlations in
- neural firing patterns, spikes and
- behavior / thought.
- Techniques, broadly defined:
- Neuromechanics
- Neuromodulation
- Neural Repair and Regenesis
- Optogenetics
- Connectomics [2]
- Neural patterns should be analogous to what is out there in the world (VS Ramachandran - Similarity of letters, image, sound [3]). Neural processing is modular (Vision - modules for color, shape, etc.).
