For anyone who thinks the specificity of neuronal connectivity is achieved through statistical mechanisms or simple proximity rules... it isn't. It requires hundreds of connectivity labels acting in combinatorial fashionpic.twitter.com/axwhVrrZDO

Of course there are lots of mechanisms to ensure the right kinds of growing axons and dendrites meet in the right places (general guidance gradients, labeled lines, selective layering...)...
...but connectivity is still established in a highly cell-type-specific manner (even often specific to subcellular domains, such as distal versus proximal dendrites)
Both the guidance of axons and dendrites and the establishment of synaptic connections are molecularly specified:pic.twitter.com/omPv3cY3wN
