Revision as of 09:17, 29 November 2014

This is the page of the Brain Hackers aka the Neurohacking/Neuromodulation London Hackspace Group. We do experiments and play around with kits to measure and alter brain activity in a non-invasive way and develop novel accessible neurostimulation means accompanied by real time measurement and feedback. Some of us are trained neuroscientists or electronics engineers, others are hobbyists. All friendly and interested people are welcome to volunteer and participate in trials, but everything is obviously at your own risk (where such risk may exist).

List of kit available by different members of the group

  • EEG – multiple copies of the 1 channel bipolar (TrueSense Kit) recorder, MindWave Mobile (1 channel), Emotiv Epoc (14 channels), KT88 (16 channels, photoic stimulation), AMEA slow potentials mapper (2 channels)

Project ideas we are interested in

Some of the project ideas we are interested in and would be eager to test in regard to different neuromodulation means. Of course, you are more than welcome to suggest other relevant ideas to test and projects to try. The possibilities are, indeed, "Limitless" (pun intended).

tDCS

  • measurement! Can it be run with simultaneous measurement of EEG activity without damaging the sensor and producing meaningful data? Currently available tDCS kits provide no real time feedback
  • interaction of tDCS with other neurostimulation means including light and low induction TMS
  • interaction of tDCS with nootropics (such as ampakines like piracetam) or ergotropics (such as modafinil and bromantane) for those already using such drugs

tACS/tRNS (transcranial random noise stimulation)

  • can the benefits of both tDCS and tACS be gained if monophasic pulsed current is used?
  • the colours of noise in tRNS ! Would they make any difference?

Coherent/decoherent light

  • does the wavelength makes much difference and what is it?
  • continuous light stimulation versus impulse stimulation with high peak power very short bursts: how would the effects differ?
  • continuous versus modulated stimulation: how do we modulate? what are the observed differences?

Weak field TMS (also called LiTMS – low induction TMS in some sources)

  • do God Helmet, "octopus", "shakti" and other Dr. Persinger's stimulation protocols actually work?
  • what other signals can be applied, and how
  • reproducing "Zhadin effect" (see Investigating the Icr Effect in a Zhadin’s Cell as a starting reading material) at Hackspace – can we do it?
  • generally, checking whether the KT (Bolzmann constant x temperature) thermodynamic limitation for biologic effects of weak magnetic fields withstands! ([http://biomag.zz.mu/pdf/2007.Binhi.ea.EBM.pdf Magnetobiology: The kT Paradox

and Possible Solutions] is a good challenge starter!)

Other

  • record and replay! Can a specific state-associated EEG recording from a selected area induce or promote this state if replayed back to the same area of the same or different person as electric or magnetic signal?
  • producing software capable of using ERP's (Evoked Response Potentials) with simple and cheap BCI like the Mindwave or TSK sensors

Folks from Mind Hacking and Biohacking groups are, of course, welcome to join in, but we surely need electronic engineering and coding enthusiasts interested in such matters!
