Bullet points : Key issues of neuroleptic surgery for seizures for example : Observable small twitching in the eyes shows that single nerves resolve impulse..
According to my studies :
Brain bit precision suggests 5 to 8Bit signals per diode may interact with Nerve cells ideally..
7Bit is cynically a rarer case; However provide us with a 14 Bit signal to resolve or the 40Bit potentially in EYE Cells & the brain may learn as we progress towards a higher resolution resolve ..
On the diode signal : Digital & Analogue : However in analogue 32Bit it at least arguably premium for us;

Temporal aliasing may improve both the level of voltages in the electrodes & increase cross diode interactions..
But also improve sensor processing.

Performance in relatively simple visual tasks, e.g. object localization, improved in nearly 100% of the tested Argus II subjects
More complex tasks, e.g. detection of motion, improved in approximately 50% of Argus II subjects.
An orientation and mobility (O&M) task based on walking towards a high-contrast target, or walking along a high-contrast line on the floor improved significantly when using the implant in a grouped analysis of Argus II subjects.
The differences between reported visual acuity of Argus II (60 electrodes) and alpha-IMS (1500 electrodes) wearers are small, despite the theoretical 8 times lower resolution of the Argus II device.
Retinal implant functionality is likely limited by many factors including physical (e.g., channel interactions), physiological (e.g., retinal degeneration) and human factors (e.g., the patient’s capability to comprehend prosthetic vision)
Retinal implant functionality is limited by many factors including electrode-electrode interactions and a sub-optimal tissue-electrode interface. At present, hardware engineering factors, such as electrode size and electrode density, may be of lesser importance.
Vision processing strategies, patient screening methods and optimizing the electrode-tissue interface are aspects of implant functionality that can be improved in the future.
The Argus II device will be continuously improved, including the implementation of advanced vision processing strategies, zooming, eye scanning, and colour coding.
Within 5 years from now, SSMP hopes to implant more than 2000 Argus II devices worldwide.
According to current plans, the next generation SSMP device will be a high-acuity retinal implant with 240 electrodes and a cortical 60-electrode implant.
