behavior/neurological
abnormal anxiety-related response ( J:110958 )
• reduced inhibition in conflict anxiety paradigms without affecting fear-conditioned and depression-related behaviors
• home cage activity did not differ
• motor coordination, strength, and sensory processing were unimpaired
• baseline concentrations and the rise in corticosterone release following anxiety tests were comparable
• cell number, mantel thickness, barrel field formation, or the expression of GABA containing neuronal markers are normal
decreased anxiety-related response ( J:110958 )
• explored the lit compartment to a greater extent in the dark-light choice test
• explored the riskier portions of the elevated plus-maze to a greater extent
• exhibited a shorter latency to begin feeding in a novel environment
increased vertical activity ( J:110958 )
• in open field

• selective restoration of 5HT2AR signaling to the cortex normalized conflict anxiety behaviors
• exhibited wild-type levels of anxiety-like behavior as measured by the open field test, dark-light choice test, and novelty suppressed feeding paradigm
• depression-related paradigms, such as the forced swim test and tail suspension test, were unchanged compared to un-restored homozygous null litter mate
