Sleep and the Vagus Nerve May Help Us Recover from Fear
Cagri Yuksel describes new research revealing that REM sleep and vagal nerve activity may play a crucial role in how the brain recovers from fear. These findings could open the door to innovative therapies for PTSD and related conditions.

When Other People Feel Like “Robots”: The Detection of Automatic Behavior in Others
Have you ever had the sense that the person you’re talking to is just a “robot”? That they’re following some script without thinking about it? New research by Ilona Bass and Tomer Ullman examines the detection of automatic behavior in other people, finding it is a common and robust phenomenon across domains.

Excitement Over Dendritic Excitations
Neurons receive synaptic inputs all along their dendrites. Dendrites can produce electrical spikes, independent of the cell body. What are these excitations for? Park, Wong-Campos, and Cohen mapped the voltage throughout the dendrites of neurons and found that dendritic excitations were mostly triggered by specific patterns of spiking at the cell body – suggesting that the dendritic excitations play an important role in regulating synaptic plasticity.
