I hate it when you get off the train and then have to go through the ticket barriers with a train load of other people. Everyone barging their ways through the gates armed with their train passes.
I was thinking about this at the same time as I was mentally rehearsing lectures for the undergraduate module I’m teaching on physiological psychology. One of my lectures focuses on Long-Term Potentiation (LTP), which is the enhancement in signal transmission between two neurons that results from repeatedly stimulating them synchronously. This is thought to be a crucial mechanism in learning and memory. Neurons increase synaptic strength by increasing the numbers of receptors at the synapse, which means that more neurotransmitters can be released from the presynaptic neuron, allowing for a stronger signal.
So, as I queue to get through the ticket barriers at Bondi Junction at 8.25am, I wish that Sydney’s rail network was able to adapt like our brains, and mobilise more ticket gates (receptors) to increase the flow of commuters (Calcium ions) through to their destination.
