The cortex is a neural network of neural networks

Gene Regulatory Network (GRN) within cells is similar to recurrent neural network (RNN). RNN is at least useful partial model for GRN.

If you think gene expression within neurons as small RNN, it's neural networks all the way down. RNN within neuron reacts to hormones and chemical signals altering the functioning of individual neurons. There is also feedback loop to other direction.

Could you please elaborate how GRNs are analogous to RNNs? I fail to see the link.

The regulation of the expression of a group of genes, can be expressed using Recurrent Neural Network formalism. Genes regulate the expression of each other with positive and negative feedback loops that are often additive or non-linear and similar to higher order RNN.

RNN nodes represent genes and connections between them are regulatory feedback loops in gene expression.
