The Next Layer of Complexity: Ion Channel Receptors

Throughout this residency I have been looking at neuronal pathways and message transmission through our bodies.  Designated synaptic clefts allow these transmissions to pass from one dendrite to the next and this is known as the action potential process – I have posted a number of images and  descriptions of this process, according to my understanding of it. However, unsurprisingly, I now find there is more to these complex neurological interactions – also involved are electronic components known as ion channels:

From 1939 to 1952, Alan Hodgkin and Andrew Huxley published a series of seminal papers that successfully described how the flux of ions across membranes is responsible for the generation of the action potential: an action potential is the transient, rapid rise and fall of the membrane voltage ( Rasband, M. N. (2010) Ion Channels and Excitable Cells. Nature Education 3(9):41)

When Neurons Fire…

Returning to some earlier research in more detail I have been investigating neuronal firing.

As has been previously discussed in earlier posts, neuronal firing is the name given to the changes that take to enable neurons to  communicate with each other. This neuronal communication occurs via electrical impulses and neurotransmitters.

As you can see from the chart above, the activity of the cultured sensory neurons can be measured in a number of ways relating to the bursts of activity, spike rate and active channels.

Ars Electronica and Wollongong Opportunities

Since  its initiation in 1979, Ars Electronica, Linz, has developed as an innovative centre for arts and ideas, particularly media art. It has sought to connect these ideas with everyday life through science and research, art and technology.

Deep Space – Exhibition, Ars Electronica

Imagine my surprise when I learned that Ars Electronica was coming to Wollongong  in February 2020 in the form of the 3Festival

Whilst this new venture will maintain the essential aims of the Ars parent organisation, it will have new unique characteristics related to Wollongong and the various stakeholders who are supporting this exciting venture.

Importantly, from my point of view, the 3Festival will have an art/science component where I will have the opportunity to showcase the first artistic outcomes of this Synapse residency..
