+=== Biological Neural Networks (BNN) ===
-A '''biological neural network''' (BNN) consists of interconnected populations of living neurons and supporting glial cells (such as astrocytes and oligodendrocytes) that process and transmit information via electrochemical signaling. Unlike static artificial neural networks (ANNs) implemented in silicon, BNNs exhibit continuous structural and synaptic plasticity. They dynamically form, strengthen, prune, or eliminate synaptic connections in response to real-time sensory feedback, enabling rapid learning and complex adaptation with minimal energy expenditure.

+=== Microelectrode Arrays (MEAs) ===
-'''Microelectrode arrays''' (MEAs) serve as the fundamental bidirectional physical interface between biological cells and digital hardware. An MEA consists of a grid of microscopic electrical contacts that simultaneously record extracellular action potentials (spikes) from nearby neurons and deliver precise electrical stimulation pulses. Advanced biocomputing setups use both planar, high-density CMOS MEAs for 2D monolayers and flexible, three-dimensional self-folding polymer shells ("miniature EEG caps") designed to wrap around 3D spherical organoids to maximize signal-to-noise ratios.

-'''Synthetic biology''' provides the foundational cellular engineering tools required for modern biocomputing. Through techniques like cellular reprogramming (producing iPSCs from adult somatic donor cells), directed differentiation, CRISPR gene editing, and optogenetics, researchers can generate standardized, reproducible batches of specific human neural cell types. Furthermore, synthetic biology allows scientists to insert light-sensitive ion channels or biochemical reporters, enabling non-invasive optical recording and targeted neurotransmitter release (such as UV-uncaged dopamine) to reinforce biological computation.

+=== Free Energy Principle (FEP) ===
 Formulated by neuroscientist Karl Friston, the '''Free Energy Principle''' (FEP) is a mathematical framework stating that any self-organizing system at non-equilibrium steady state must minimize its variational free energy—effectively minimizing informational entropy, uncertainty, or "surprisal." In biocomputing architectures like Cortical Labs' DishBrain, the principle operates as an unsupervised training driver:
 * When the neural network produces an incorrect response (e.g., missing a ball in ''Pong''), the interface delivers chaotic, unpredictable electrical noise.
