You are invited to NBD Invited Speaker Seminar on Sparse coding for odour-specific memories through homeostatic plasticity.
Stimulus-specificity of associative memories is enabled by sparse coding (only a small fraction of neurons responds to each stimulus). We found that optimal sparse coding in the fruit fly's memory centre, the mushroom body, is maintained by homeostatic plasticity, where neurons compensate for disturbances away from their 'preferred' activity level. We observe both physiological and anatomical compensation and show using computational models that this compensation enhances memory capacity.
