Biocomputing uses synthetic biology, such as miniature clusters of lab-grown cells called organoids, to create computer architecture.

Swiss company FinalSpark 's " Neuroplatform " is powered by human-brain organoids.

Neuroplatform uses a series of processing units hosting four spherical brain organoids each.

If perfected, this training could eventually allow organoids to mimic silicon-based AI .

Mycelia , or networks of fungal strands, exhibit spiking electrical potentials similar to those found in neurons.

Adamatzky hopes to take advantage of these electrical properties to create a brainlike fungal computing system.

"Fungal computing offers several advantages over brain-organoid-based computing," he says.

An ongoing bioethical debate concerns whether mini brains could gain consciousness.
