New paper alert! 🚨
In this study we explored how interactions between the locus coeruleus (LC), basolateral amygdala (BLA), and the ventromedial prefrontal cortex (vmPFC) affect freezing behavior and extinction learning.

These results reveal a circuit mechanism by which LC–NE biases activity of BLA→vmPFC to generate a heightened fear state. The better understanding of this circuit may help explain stress-related impairment of fear extinction in disorders such as PTSD.

Congratulations to the newly minted Dr. Hugo Bayer (@HugoBayer1 ) !! Great work and super cool story ! 🍾👏🥳🎉
We looked at evidence from all sorts of fear memory reconsolidation studies and tried to determine what is known about the temporal dynamics of different systems that contribute to memory reconsolidation and persistence after recall.

How are long-term memories stored in the amygdala? How are old memories integrated with new memories over time? We discuss this and more in a new review led by @JianfengLiu6 with @HugoBayer1 and @StephenMaren. biologicalpsychiatryjournal.…

📣 New Cai Lab paper in @CellReports!
We show that a stressful experience can produce different types of memories! We also find that the basolateral amygdala (BLA) & ventral hippocampus (vHC) differentially contribute to these memories 🧠

🌟Review Alert! Excited to share our latest article, where we explore the effects of serotonergic #psychedelics and related substances (e.g., MDMA) on extinguishing and reconsolidating aversive memories, expressing fear/anxiety, and locomotion in rodents.

The first piece of my PhD work is out in @npp_journal! We explored the effects of infralimbic stimulation and protein synthesis inhibition during fear memory consolidation🧵

These findings suggest that during the initial stages of *fear* memory consolidation, a trace that *opposes fear* is established in the IL, which is counterintuitive or perhaps paradoxical.
