Questions are visible immediately; open a card to reveal the answer.
What is a biocomputer?
A system in which biological material performs a meaningful information-processing role.
What is a multielectrode array (MEA)?
An array of electrodes used to record electrical activity from cells and, in many systems, deliver electrical stimulation.
What is closed-loop feedback in a neural biocomputer?
A setup in which recorded neural activity affects the next stimulus or environmental state, creating a feedback cycle.
What is organoid intelligence?
A research programme studying computation, learning and information processing in brain organoids coupled to interfaces and software.
What is wetware computing?
An informal term for computing that uses living biological material as part of the information-processing substrate.
What is reservoir computing?
A computing approach that uses the dynamics of a complex system as a high-dimensional transformation, with a simpler readout trained on its states.
Why are MEAs important in biocomputing?
They provide a bidirectional electrical interface between living neural networks and electronic systems.
What did DishBrain demonstrate?
Task-relevant adaptation in cultured cortical neurons interacting with a simulated Pong environment through structured electrical feedback.
What is Brainoware?
A brain-organoid reservoir-computing system reported in Nature Electronics in 2023.
What is the CL1?
A commercial Cortical Labs platform that grows neurons on a silicon-based multielectrode interface with life support, stimulation, recording and software access.
What does FinalSpark provide?
Remote access to maintained human neural organoids for stimulation, recording and wetware-computing experiments.
What is the difference between a biocomputer and a neuromorphic chip?
A biocomputer uses biological material; a neuromorphic chip is electronic hardware designed around principles associated with nervous systems.
Why is reproducibility difficult in living-neural computing?
Living cultures vary biologically over time and between preparations, so identical electronic inputs can meet different neural states.
Why does whole-system energy matter?
A fair energy comparison includes life support, sensing, stimulation, control electronics and other infrastructure alongside the biological tissue.
Does neural activity prove consciousness?
No. Neural activity, plasticity and task responses do not establish consciousness.
What is a preprint?
A research manuscript made public before formal peer review.
What is synthetic biological intelligence (SBI)?
A broad research area concerned with engineered living neural systems that sense, process information, adapt and interact with artificial environments.
What is a brain–computer interface (BCI)?
A system that measures or stimulates a living brain to exchange information with an external device; the term describes an interface, not a biocomputer category by itself.
