I tried 3.7mA at 40Hz
It also doesn’t add much overhead

The NeuroMyst Pro Plus (+) is our next upcoming product. This week, we’re updating our community on our progress and next steps as we prepare for a 2024 launch.
Which waveforms will be on the Pro+?
You will get the standard tDCS and tACS modes.
You will also get two new waveforms.
• tCFS (transcranial cross-frequency stimulation)
• tPCS (transcranial pulsed current stimulation)
We chose tPCS for a couple of reasons. One, tPCS was actually more requested than tICS (transcranial interferential current stimulation) from our advanced user community. Two, after completing internal testing, we decided that tICS will be better and more stably implemented with upgraded hardware. tICS uses very fast frequencies, and we want to upgrade our hardware to best support this waveform.
This means tICS and tRNS will be reserved for our most advanced pro model, the Pro Max. The NeuroMyst Pro Max will be released after the Pro+.

What is the expanded tACS model?
Standard tACS mode in the Pro+ uses frequencies from 0.1-80Hz. These cover all the standard brain rhythms: delta, theta, alpha, beta, and gamma.
The expanded tACS model introduces infra-low frequencies below 0.1Hz, and high gamma and ripple frequencies above 80Hz.
Infra-low frequencies will go from 1mHz-99mHz. 1mHz = 0.001Hz. These much slower frequencies track more with gradual shifts in state of mind, and they are a mainstay in modern neurofeedback training. https://www.neurofeedbackadvocacyproject.com/about-nfb
High gamma and ripple frequencies go from 80-200Hz. These faster frequencies target neurons that fire faster, and they produce less skin sensations. People have used these lower-sensation waveforms for meditation and going to higher amplitudes with less skin sensations to achieve stronger effects.

Working memory (WM) is a cognitive function that enables temporary storage and manipulation of information for tasks like reasoning and decision making. While research has focused on oscillatory activity in narrow frequency bands, most neuronal activity is asynchronous, manifesting as aperiodic activity. Aperiodic activity is characterized by a 1/f power law distribution, and its slope is speculated to reflect the E:I balance. Recent evidence suggests aperiodic activity dynamically changes with cognitive demands, including WM, but lacks causal evidence. To investigate this causal connection, we collected EEG data from participants (n = 36) completing two days of a visual delayed continuous report task with varying WM loads. We developed a novel non-invasive electrical stimulation paradigm that mimics aperiodic activity: transcranial Random Aperiodic Stimulation (tRAS). Day two included this paradigm targeting the fronto-parietal network with the goal to causally manipulate endogenous neural aperiodic activity to become steeper or flatter while they performed the task. From day 1, we replicate classic WM findings: worse performance on higher WM load conditions than lower loads. We hypothesize that steeper stimulation causes the slope of aperiodic activity to increase, and will be paired with an increase in WM performance. If our results support our hypothesis, this research is critical for aging, since aperiodic activity flattens with age, paralleling a cognitive decline. If we find evidence for a direct, causal connection between aperiodic activity and WM, we have opened the door to finding a way to slow mental aging and improve the longevity of their minds.
