If each neuron in a brain has 1000 connections, this means a cat has roughly 250 billion synapses, and a dog has 530 billion synapses. Synapse count generally seems to predict higher intelligence, with a few exceptions: for instance, elephants technically have a higher synapse count than humans yet display lower intelligence. The simplest explanation for larger synapse counts with lower intelligence is a smaller amount of quality data. From an evolutionary perspective, brains are “trained” on billions of years of epigenetic data, and human brains evolved from higher quality socialization and communication data than elephants, leading to our superior ability to reason. Regardless, synapse count is definitely important. Again, the explosion in AI capabilities since the early 2010s has been the result of far more computing power and far more data. GPT-2 had 1.5 billion connections, which is less than a mouse’s brain (~10 billion synapses). GPT-3 had 175 billion connections, which is getting somewhat close to a cat’s brain.
