Synaptic Plasticity


Synaptic plasticity is the ability of synapses in the nervous system to grow or shrink over time, usually in relation to changes in their activity levels. Since interconnectivity of synapses is believed to be a fundamental aspect in memory and learning, a deeper understanding of synaptic plasticity is key to understanding how these processes are regulated. Due to the elongated nature of many neural cells, many mRNAs are believed to localise at synapses before being translated into proteins that are critical in the processes involved in plasticity. 


In the Davis lab we use the Drosophila neuromuscular junction as an easily accessible model to study synaptic plasticity and the mRNA localisation associated with this process.
