Researchers have successfully developed an ultra-sensitive pressure sensor for electronic skin modeled after the nervous system in the human brain. This technology is applicable to future devices, including AI-based digital healthcare devices, and is expected to be utilized across various fields, such as transparent displays and wearable devices, due to its transparency and physical flexibility.

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this 'negativity bias,' which can fuel the development of depressive symptoms, had previously remained largely unknown. To shed light on the question, scientists decided to explore the amygdala and observe how it functions during depressive episodes. Their findings suggest that a depressive state alters certain specific neural circuits, leading to a reduction in the activity of neurons involved in pleasant perceptions of positive stimuli and an overactivation of those responsible for the perception of negative stimuli.
