Neurogenesis in the rat amygdala was examined with 3H-thymidine radiography. The animals were the offspring of pregnant females given two injections of 3H-thymidine on consecutive days in an overlapping series: Embryonic day (E) 12 + E13, E l 3 + E14. . . E21 + E22. On 60 days of age, the percentage of labelled cells and the proportion of cells added during each day of formation were determined...

Estrogen stimulation of the medial amygdala (MEA) of the brain promotes male rat mating behavior. However, selective stimulation of either of the estrogen receptor subtypes found in the MEA (ERα or ERβ) does not support mating behavior. We tested the hypothesis that dual stimulation of ERα and ERβ is required to activate estrogen-dependant neural circuits in the MEA responsible for mating by lo...

Auditory information critical for fear conditioning, a model of emotional learning, is conveyed to the lateral nucleus of the amygdala via two routes: directly from the medial geniculate nucleus and indirectly from the auditory cortex. Here we show in the cortico-amygdala pathway that learned fear occludes electrically induced long-term potentiation (LTP). Quantal analysis of the expression of ...

Emotionally arousing pictures induce increased activation of visual pathways relative to emotionally neutral images. A predominant model for the preferential processing and attention to emotional stimuli posits that the amygdala modulates sensory pathways through its projections to visual cortices. However, recent behavioral studies have found intact perceptual facilitation of emotional stimuli...
