FeaturedNeuroscience·September 19, 2020·6 min readHow Fear Persists in the Mouse BrainWhen a mouse senses a threat, neurons in the ventromedial hypothalamus become activated and remain active for ten seconds after the threat is removed. Fear responses could be induced by artificially stimulating these neurons. Artificially silencing the neurons reduced fear behavior.Read More

FeaturedNeuroscienceOpen Neuroscience Articles·July 13, 2020·3 min readWhy Are Memories Attached to Emotions so Strong?Hippocampal neurons that respond to fearful stimuli relay that information to the amygdala. These neurons synchronize when memories of the stimuli are later recalled. The synchrony is critical to establish fear memories and the greater the synchrony, the stronger the memory becomes.Read More
