For their recent study, Paci et al. (2022) encoded a fear memory by pairing a mild electric foot shock with an audible tone. Once their lab rats were conditioned to fear the auditory tone by itself, they implanted electrodes to monitor neuronal activity within the PAG. When the rats heard the fear-conditioned tone, it triggered a momentary freeze response, and specific neurons in the PAG simultaneously "lit up."

This research increases our understanding of how survival networks rooted in subcortical brain areas cause the body to automatically freeze in response to fear. When the cerebellum is functioning well, a momentary freeze response promotes survival. However, Paci et al. (2022) found that when cere...
Neuroscientists at the University of Bristol have discovered fear mechanisms rooted in the cerebellum that could lead to new anti-anxiety medications and treatments for post-traumatic stress disorder a.k.a PTSD (
Notably, when a rat's cerebellum was functioning properly, the freeze response was brief and didn't stop an animal in its tracks for too long.
However, Paci et al. (2022) found that when the cerebellum's ability to communicate with the PAG was blocked, freeze responses went into overdrive a...
In animal experiments using fear-conditioned rats, Paci et al. (2022) found that the cerebellum modulates how another brain area called the periaqueductal gray (PAG) triggers automatic defensive behaviors such as freezing in place during times of perceived danger.
The findings suggest that the cerebellum plays a crucial role in coordinating perfectly-timed behavioral responses to threatening stimuli. But cerebellar dysfunctions can cause havoc with perfectly-timed freeze responses. Without a well-functioning cerebellum, the freeze response lasts too long.
"These findings show that the cerebellum is a part of the brain's survival network which regulates fear-memory processes. [This study] raises the possibility that disruption of the cerebellum might underlie anxiety and other fear-related disorders, th...
The cerebellum coordinates fluid motor movements in sports and daily life. It also coordinates our thoughts, as well as coordinating our movements. As part of a survival network, it facilitates gracefully taking flight, fighting it out with well-coordinated muscle movements, or freezing in place ...
"Importantly, our results show that the cerebellum is part of the brain's survival network that regulates fear memory processes at multiple timescales and in multiple ways; raising the possibility that dysfunctional interactions in the brain's cerebellar-survival netwo...
"Until now, little was understood about how the cerebellum modulates neuronal activity in other brain regions, especially those related to fear and anxiety"

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.
This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.
Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.
Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
