Perineuronal nets protect fear memories from erasure.

2 Sep 2009 In adult animals, fear conditioning induces a permanent memory that is resilient to erasure by extinction. In contrast, during early postnatal development, extinction of conditioned fear leads to memory erasure, suggesting that fear memories are ... Read more...

Functional imaging of stimulus convergence in amygdalar neurons during Pavlovian fear conditioning.

5 Jul 2009 BACKGROUND: Associative conditioning is a ubiquitous form of learning throughout the animal kingdom and fear conditioning is one of the most widely researched models for studying its neurobiological basis. Fear conditioning is also considered a ... Read more...

Oscillations in the basolateral amygdala: aversive stimulation is state dependent and resets the oscillatory phase.

29 Jun 2009 Slow oscillations (<1 Hz) in neural activity occur during sleep and quiet wakefulness in both animals and humans. Here we show that in urethan-anesthetized animals, neurons in the basolateral amygdala in vivo display a slow oscillation between ... Read more...
