# Summary of #hplusroadmap IRC Discussion

• A novel non-invasive brain imaging method using light was shared, though participants questioned aspects of the methodology, specifically why researchers didn't apply visual stimulus to determine the point spread function.

• Participants discussed transcranial direct current stimulation (tDCS), sharing a commercial device described as "easy to use, precise and safe," while also debating the technical distinction that tDCS reportedly doesn't induce neuronal action potentials unlike TES and TMS.

• The memory requirements of the V8 JavaScript runtime were discussed in the context of embedded hardware systems, suggesting interest in implementing advanced software on resource-constrained devices.

• Biohacking resources were mentioned, including Carolina K12 bacterial transformation kits (under $100) as an entry point for DIY biology, and a biohackerspace in Houston (ARC) was highlighted as a resource for laboratory work.

• The conversation touched on the perceptual phenomenon of chronostasis (the stopped clock illusion), with participants sharing Wikipedia information on this cognitive effect.

• There was discussion about programming language preferences, with participants noting they use Python for personal projects despite working professionally with JavaScript and Ruby.
