Snapshots in Neuroscience: Aplysia inking during sensitization
This image has been selected to showcase the art that neuroscience research can create.
As described by Dr. Puthanveettil and colleagues: The image shows inking response to sensitization training in the marine sea slug, Aplysia california. Aplysia releases a cloud of dark purple ink in response to a noxious stimuli. Sensitization training, a form of non-associative learning, involves delivering brief electric shocks to the tail and measuring siphon withdrawal reflex response. In this behavioral training paradigm, a brief electric shock to the tail produces short-term sensitization lasting several minutes whereas four spaced shocks produce long-term sensitization lasting several days.
Sadhu et al show by quantitative proteomics analysis that short-term and long-term sensitization training differently alter the composition of protein cargos transported by molecular motor Aplysia kinesin heavy chain 1 (ApKHC1). Their results suggest regulation of the expression and composition of anterogradely transported cargos during learning and underscore the significance of kinesins in establishing long-term memory storage.
