RefSeqP: # of curated protein coding genes in the orthologous region of HSA21q. Boundaries: genes at the centromeric and telomeric ends of the trisomic segment.
Behavior: see Box 1. Stm, short term memory; Ltm, long term memory.
LTP, long term potentiation; LTP-1, LTP-24, LTP measured at one and 24 hours after initial stimulation. LTD, long term depression; BFCN, basal forebrain cholinergic neurons; CB-GC, cerebellar granule cells.
, enhanced compared with euploid controls.
