  1. Transcripts manually curated into functional categories by their annotations. Count is the number of transcripts mapping to a function; DE indicates the number of transcripts differentially expressed in nervous system tissues compared to muscle tissues (adj p < 0.05); up and down signify the number of DE transcripts upregulated (positive log2fold change) or downregulated (negative log2fold change), respectively
