# Key Points from Transhumanist and Neuroscience Discussions

• Researchers comparing human and chimpanzee cerebral organoids found remarkably similar structures with only subtle differences in cortical progenitors, potentially illuminating key aspects of human neocortex evolution.

• A Harvard study identified a potential neural network associated with consciousness involving the pontine tegmentum, insular cortex, and anterior cingulate cortex, while separate research demonstrated that electrical stimulation of the parabrachial nucleus can induce reanimation from general anesthesia.

• Advanced neuroimaging techniques were extensively discussed, including synchrotron-based high-energy x-rays (Brain-X) for creating nanoscale brain maps without tissue damage, and Russell Hanson's work on nanoCT with gold nanoparticles for synapse-resolution scanning.

• Participants debated the limitations of EEG as a measurement tool, arguing that current sampling rates are insufficient to capture neural complexity compared to more direct electrophysiological methods.

• Significant BCI advancements were highlighted, including Second Sight's visual cortex stimulator implant in a blind person and the development of implantable microcoils for intracortical magnetic stimulation as an alternative to traditional electrical stimulation.

• Novel cellular tracking methods were discussed, including "rapidly evolving homing CRISPR barcodes" for lineage tracing and brainbow technology for RGB marking of neurons in adult brains.
