Squirrel Tamer was built after decades of biomedical engineering, neuroscience, and human-centered design of products made specifically for brain health.  "Tamer" uses targeted mechanical vibration and acoustic stimulation to regulate the neural pathways that govern attention, impulsivity, and fight-or-flight response. It’s not magic—it’s measurable. It naturally and effectively excites the auditory and vestibular nerve which are both very strong sensory inputs.  

​​

Vibration and acoustical stimulation was specifically chosen and optimized for its safety profile (over electrical/magnetic stimulation or caloric or chemical stimulation). We have dialed in how we implement this and have tested against electrical stimulation, and generic vibration or musical methods. Clinical trials followed this protocol:

• Randomized: Participants were randomly selected to use either Tamer with specifically chosen stimuli, or an exact duplicate that used generic vibration, referred to as the "active control" since it could provide stimulation that indeed provide a positive effect. This is a much higher bar to differentiate against compared to a placebo.

• Double-blind: None of the doctors, techs, or participants knew which device they were given until the study was concluded.

• Principal Investigators:  Were double board certified in neurology and psychiatry and were experienced in clinical trials as well as treating patients daily.

• Data Collection:  All tests were computerized with no human intervention, thus eliminating any human bias from the participant or the doctor's interpretation of the results.

• Individual Control: Each individual served as their own control AND the two populations were compared for statistical differences.

​

Here were the results:

​

First:  Referring to the first image: Cerebral blood flow was increased immediately.  Cerebral blood flow is not just a passive delivery system. It’s a dynamic, regulated mechanism that adapts to the brain’s moment-to-moment demands. Enhancing CBF has profound implications for attention, metabolic activity, and neural repair.  In a 2023 study published in Scientific Reports showed that increased CBF directly supports attentional control by optimizing oxygen and glucose delivery to high-demand neural circuits. Other studies have shown that increased cerebral blood flow supports neurovascular coupling and sustaining energy demands of active neurons, and increased CBF promotes angiogenesis, neurogenesis, and structural resilience post-injury or degeneration.

Second: Considering the neuromodulation results, specifically 24 metrics of auditory and visual attention, impulsivity, distraction and executive function and referring to the table of charts:

Compared to the active control (bar on the left of each chart), TAMER (bar on the right of each chart) showed improvement over all metrics except faster reaction time compared to the Active Control. The active control showed that reaction time speed increased, but accuracy in executive function worsened. This is a similar result to too much caffeine. TAMER, on the other hand, showed more consistent, and slightly slower reaction times with improvement across all metrics.

​​

Looking at whether these results were clinically significant, Tamer showed clinically and statistically significant improvement over 21 of the 24 metrics of attention while the active control showed improvement over 6 or the 24 metrics, but not as strong as TAMER in 4 of the 6 as shown in the gra.
