Effects of D-amino acid oxidase inhibition on memory performance and long-term potentiation in vivo [PDF]
, 2013 N-methyl-d-aspartate receptor (NMDAR) activation can initiate changes in synaptic strength, evident as long-term potentiation (LTP), and is a key molecular correlate of memory formation.

2-Chloroquinoline-3-carboxylic acid
Acta Crystallographica Section E, 2010 The crystal structure of the title compound, C10H6ClNO2, can be described by two types of crossed layers which are parallel to (110) and (overline{1}10). The crystal packing is stabilized by intermolecular C—H...O and O—H...N hydrogen
