## Critical Evaluation
### Fundamental Mechanistic Concerns
**Cell-type specificity claims are unsupported.** The analysis asserts PV interneurons exhibit "heightened mechanosensitivity due to dense Kv3.1/3.2 channel expression." This conflates voltage-gated potassium channels with mechanosensitive channels. Kv3 channels are voltage-sensitive, not mechanically gated. The mechanistic link between Kv3 expression density and enhanced mechanical sensitivity has not been demonstrated. Furthermore, Piezo1, TRPA1, and TREK-1—the mechanosensitive channels invoked—are expressed across neuronal populations, not preferentially in PV cells. Claiming "direct PV interneuron recruitment" implies molecular targeting capability that tFUS fundamentally lacks.
**Causal direction remains undetermined.** The hypothesis treats gamma oscillation loss as a primary driver of AD pathology, but the evidence base shows correlation. The Iaccarino et al. study demonstrated that 40 Hz entrainment reduced amyloid burden—it did not establish that gamma loss causes amyloid accumulation.
