Why do you feel neural circuits are important to study?

Genes and environment converge at the level of neural circuits in the brain. We know a lot about the individual genes involved in neural transmission, and how individual neurons respond in brain circuits as a consequence of certain stimuli.

Drug repurposing: ALS gets keymaster and gatekeeper tech to delay progression

Drug repurposing: ALS gets keymaster and gatekeeper tech to delay progression

Neurons communicate with each other through synaptic transmission, which involves both the release of chemical neurotransmitters and electrical activity. This communication can be either excitatory or inhibitory. Excitation is like the gas pedal in your car and inhibition is the brake pedal. Too much gas and you’ll speed off the road; too much brake and you don’t go anywhere. In a healthy brain,…

Fast trial innovation on mental health: neurobiology of depression has a new friend

A first-of-its-kind trial has demonstrated that a receptor involved in the brain’s reward system may be a viable target for treating anhedonia (or lack of pleasure), a key symptom of several mood and anxiety disorders. This innovative fast-fail trial was funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, and the results of the trial are published…

Caught in the Act: Study Catches Brain Circuits as They Rewire

Caught in the Act: Study Catches Brain Circuits as They Rewire

In a technical feat with ramifications for our understanding of how experiences imprint themselves as lasting memories, and how faulty circuit wiring leads to neurological disease, UC San Francisco scientists have caught brain circuits in the act of rewiring themselves to change how they respond to sensory input.

The study — published October 7, 2019 in Proceedings of the National Academy of…

How to Map the Circuits That Define Us

How to Map the Circuits That Define Us

Neuroscientists want to understand how tangles of neurons produce complex behaviors, but even the simplest networks defy understanding Marta Zlatic owns what could be the most tedious film collection ever. In her laboratory at the Janelia Research Campus in Ashburn, Virginia, the neuroscientist has stored more than 20,000 hours of black-and-white video featuring fruit-fly (Drosophila) larvae. The…

Scientists Develop "Off-Switch" for the Human Brain

Scientists Develop “Off-Switch” for the Human Brain

Research could help towards developing treatment for neurological disorders such as epilepsy.

Scientists have developed an “off-switch” for the brain to effectively shut down neural activity using light pulses.

The white matter microstructure, the communication pathways of the brain, continues to develop/mature as one ages. Studies link age-related differences in white matter microstructure to specific cognitive abilities in childhood and adulthood.

Most prior studies, however, did not include individuals from the entire life span or evaluated a…

Brain circuits multitask to detect, discriminate the outside world

Imagine driving on a dark road. In the distance you see a single light. As the light approaches it splits into two headlights. That’s a car, not a motorcycle, your brain tells you. A new study found that neural circuits in the brain rapidly multitask between detecting and discriminating sensory input, such as headlights in the distance.
