# Key Points from Transhumanist IRC Discussion

• Researchers discussed ultrasound neurostimulation technology, highlighting how focused ultrasound at 0.50 MHz with power levels around 64.53 mW/cm² can trigger muscle movements in mice, representing a non-invasive method for brain stimulation.

• A 500-element ultrasound phased array system was described that uses piezoelectric material with ceramic pillars in a polymer matrix to focus ultrasound through the skull without surgical intervention, demonstrating advances in non-invasive brain interfaces.

• The FDA-approved ExAblate device (by InSightec) was mentioned as being in clinical trials for brain applications including glioblastoma and neuropathic pain treatment, with claimed 1mm precision targeting capabilities.

• Infrared nerve stimulation technology, specifically the Aculight Capella system, was discussed as offering more precise neural targeting than electrical stimulation, though with limited depth penetration.

• The conversation distinguished between ablative (destructive) and stimulative applications of ultrasound on neural tissue, noting that the difference lies primarily in power levels rather than frequency.

• A 3D-printed peristaltic pump mechanism (http://peristalsis.tentacleriot.eu/) was shared, representing an interesting development in DIY biohacking hardware that could enable more accessible biotechnology experimentation.

• The biohacking event "FutureLabCamp" was referenced with documentation, indicating organized community efforts around open-source transhumanist technology development.
