Focused ultrasound allowed researchers to record and monitor brain activity in a non-invasive way. The technology allowed the researchers to predict movement. Read More
A new theoretical study proposes new models outlining the relationship between personality, genes, and behaviors. Researchers also propose a method to discover where personality resides in the brain, and how it relates to other psychological functions including memory and emotion. Read More
Activity in the medial preoptic area tilts the mouse brain toward love and affection, while activity in the ventromedial hypothalamus is associated with more aggressive or hateful acts. Read More
Hard wired neural circuits in mice that govern aggression are strengthened following victories in aggressive encounters. Synapses in the hypothalamus show signs of LTP following aggression training. Read More
When 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
Study identifies a different set of individual neurons in the medial frontal cortex that is responsible for memory-based decision making. The findings have implications for the treatment of Alzheimer's disease, schizophrenia, and other disorders associated with problems in cognitive flexibility. Read More
The brain chooses between two neural systems responsible for emulation learning and imitation learning. Study reveals how the brain chooses which strategy to employ when faced with an observational learning task. Read More
Using mouse models, researchers seeded alpha-synuclein aggregates in gut neurons and discovered the clumps can travel to neurons in the brain. Read More
Study identifies rare brain cell types that are unique to male mice, and others that are unique to females. The cells were discovered in the hypothalamus, a region of the brain that governs both aggression and mating behaviors. Read More
Stable memories are encoded by teams of neurons firing in synchrony, providing redundancy that enables the memory to persist over time. Read More
Newly designed microbots can deliver vital drugs throughout the human body. The microbots can traverse the body and penetrate bodily mucus to efficiently deliver medications to target sites. Read More
Serotonin produced by the raphe is critical for sleep in both mice and zebrafish. The firing of neurons in the raphe and the release of serotonin may help the brain build up better sleep pressure. The results may explain why some sleep-related side effects of antidepressants increase serotonin in the brain. Read More
