# Key Points from IRC Discussion

• A neuroscientist specializing in EEG and attention disorders discussed neurofeedback (NFB) efficacy for ADHD, sharing Martin Arns' meta-review demonstrating that neurofeedback has achieved "Level 1 Best Support" status as an intervention for attention and hyperactivity behaviors.

• The discussion revealed that commercial EEG devices like Emotiv and Neurosky have significant limitations for brain-computer interfaces, with PocketNeurobics mentioned as a superior 2-channel EEG alternative for serious applications.

• Research on neural tissue transplantation was shared, specifically about induced pluripotent stem cell-derived neural cells surviving in non-human primate brains, indicating progress in this field.

• The neurological basis of ADHD was explored, with the expert explaining that hyperactivity is secondary to core response inhibition issues, and that neurofeedback primarily targets sensorimotor strip-based training rather than just prefrontal cortex interventions.

• Transcranial direct current stimulation (tDCS) research was discussed, focusing on its neurobiological effects as a non-invasive brain stimulation technology with potential therapeutic applications.

• Participants debated the viability of polyphasic sleep (sleeping in multiple shorter periods throughout the day), with the consensus being that few people find it sustainable long-term regardless of their employment situation.

• An article about declining global birth rates titled "What Happens When Half The World Stops Making Babies" was shared, prompting discussion about potential demographic consequences.
