- synaptic remodeling variant
The polarity reversal process by which synaptic components are removed from one side of the synapse and then reformed on the opposite cell does not occur or occurs in a different manner than in controls. In C. elegans, at the end of the L1 stage, the DD neurons undergo a complete polarity reversal such that the ventral synapses disappear and new synapses are formed on opposing dorsal body muscles.
- fewer neurons
Animals exhibit fewer neurons compared to control animals.
- extra neuron
Animals produce an excess number of neurons compared to controls.
- aberrant posteriorly-directed neurite
Any neurite that is extended towards the posterior of the animal from neurons that in wild-type animals make only anterior projections (e.g. D-type neurons in C. elegans).
- CAN cell migration variant
Variation in the migration pattern of CAN neurons. In C. elegans, CAN neurons move posteriorly from their birthplace in the head to positions near the middle of the embryo.
