Active zone release probability is correlated with calcium channel density and calcium influx at single release sites, with release strength increasing in an activity-dependent manner during synapse maturation.
Interspecies comparison of transcription factor occupancy during embryogenesis reveals potential co-operative relationships between factors and uncovers the inherent plasticity of developmental enhancers to overcome divergence in transcription factor occupancy.
Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.
Sperm and egg development are temperature sensitive, enabling males and females to significantly improve their reproductive success by matching gamete function to varying thermal environments for fertilisation and offspring development.
Teaching signals from "tutor" brain areas should be adapted to the plasticity mechanisms in "student" areas to achieve efficient learning in two-stage systems such as the vocal control circuit of the songbird.
