Emotional Modulation of the Attentional Blink by Pleasant and Unpleasant Pictures
When shown a rapid series of images, attention to a second target that follows in short proximity to a first is diminished--a phenomenon sometimes called an "attentional blink." Three experiments compared detection of motivationally relevant pleasant, unpleasant, and neutral pictures when they appeared as the second target following a neutral (Experiment 1), unpleasant (Experiment 2) and pleasant (Experiment 3) picture target. The second target f…
Brief Flight to a Familiar Enclosure in Response to a Conditional Stimulus in Rats
The authors observed brief, directed movement to a familiar enclosure in rats to determine whether this behavior is part of a rat's defensive repertoire when exposed to a conditional-fear stimulus. In Experiment 1, upon exposure to the compound conditional-fear stimulus of tone and light, only rats that received paired presentations of the conditional stimuli and shock fled into a small, familiar enclosure where they then froze. Rats that had rec…
Amygdala and periaqueductal gray lesions only partially attenuate unconditional defensive responses in rats exposed to a cat
Ventral and dorsolateral regions of the midbrain periaqueductal gray (PAG) control different stages of defensive behavior
Rats that receive nociceptive electric shock in an environment normally show the conditional fear-induced defensive response of freezing when returned to that environment. If several electric shocks are given in a massed manner they will condition less freezing than the same shocks given in a distributed manner. If a single shock is given immediately after placement in the chamber it does not support any conditioning, although the same shock give…
