Jeferson Machado B. Sohn

A neuroscientist at the Dept. of Pharmacology in the Federal University of Paraná. My current research aims to evaluate mechanisms to attenuate fear memory.

Sharing our published paper that evaluates the activity of phosphodiesterase 4 activity in fear memory extinction persistence. We showed that PDE4 inhibition 3 h after the fear extinction improved the persistence of the extinction memory. #neuroscience

as vezes lembro que to no décimo semestre e começo a me tremer pq meu estágio no fórum criminal e no hospital vão mudar completamente

I'm pleased to share our latest publication, which evaluates the effects of phosphodiesterase 4 on the reconsolidation of object recognition memory.

Excited to share our new study in Scientific Reports!
> PDE4 inhibition in the hippocampus shifts memory from reconsolidation to extinction.
> Roflumilast (ROF) enhances extinction via proBDNF expression.

Excited to share our latest paper!
> Systemic PDE5 inhibition triggers memory generalization.
> Impaired remote object pattern separation.
> Effects rely on reconsolidation and anterior cingulate cortex activity.

@bertogliolab @MaastrichtU @CristinaStern @tim_vanmierlo @fabriciodomonte Thank you Leandro for accepting to evaluate my study @bertogliolab

[Bertoglio lab (FMC/UFSC) @bertogliolab]

Had the pleasure of serving on the committee that evaluated @JefersonSohn's doctoral thesis at @MaastrichtU today. Fascinating findings! Congrats to his supervisors, @CristinaStern and @tim_vanmierlo, as well. @fabriciodomonte

check our new study about THC effects on fear memory:
A conventional dose of THC given before retrieval impairs memory labilization.
Ultra-low dose of THC given before retrieval impairs memory reconsolidation. #THC #Cannabis #Science

An interesting point is that we used a lower amount of Ayahuasca and its compounds than is usually consumed. #Science #Neuroscience #UFPR #Pharmacology #FearMemory #psychedelics #PTSD #Ayahuasca

[Jeferson Machado B. Sohn @JefersonSohn]

Hello everyone, this is the new study from our group. Here we evaluated the effects of Ayahuasca on fear memory reconsolidation. Our results showed that Ayahuasca impaired fear memory reconsolidation, reducing fear expression in a long-lasting way. https://t.co/AEm7M3td7v

It was a great symposium about the neurobiology of learning and memory!

Are your Intrested in the fear memory reconsolidation? My study aimed to evaluate the effects of PDE4 inhibition on that. My poster is the 50 at session 7. See you! @FENSorg #fens2022 #FENS #Science #Paris #neuroscience
