It appears that there are many parallels between the brain and an electronic chip at multiple levels.
The notion of memory, the notion of electric potential, and consumption of energy!
This started with a discussion triggered by @Arunan to find ways of measuring action potential (Also see this) using some electrodes! In relation, @G_N posted an interesting video and @jaikishan suggested that every cell in our body is a cell (LOL a battery! ) (See Microbial Fuel Cell)
Also, there was discussion around the efficiency from energy consumption pov by @jtd and @vvcstemplay eventually leading to @jtd saying “Which begs the question what is The nature of memory? Does it even have any resemblance to a computers memory?”.
