911 Operators Vulnerable to PTSD Symptoms

911 dispatchers deal with traumatic scenarios every day, but from a distance — and it turns out that combination can make them vulnerable to symptoms of post-traumatic stress disorder (PTSD).  New research, published in the Journal of Traumatic Stress, found that dispatchers who answer 911 and 999 emergency calls suffer emotional distress which can lead to [...]

Timely inhibition

This week?s paper is by Abigail Person and Indira Raman and is about information transmission between two cell populations in the cerebellum ? purkinje cells in the cortex and their targets in the deep nuclei. Purkinje cells are justifiably famous for their spectacular anatomy  which enables integration of thousands of inputs. This paper, however, is about their output and how these exclusively GABAergic cells control the activity of downstream neurons. Conventional wisdom holds that there should be a straightforward inverse relationship between the firing rate of the two populations, but this has not always been observed. Person and Raman present a new solution based on spike timing ? when purkinje cells spike asynchronously, their targets are inhibited (as expected), but when they spike synchronously, nuclear neurons can spike during the gaps in inhibition and end up time locking their activity to their inputs.  Read more
