Journal Club: Tracing light’s effect on mood and learning in mice from the eye to deep within the brain

Posted on October 11, 2018 by Carolyn Beans

To the mammalian eye, light offers more than just sight. “Light is so important for many innate functions,” says neuroscientist Samer Hattar of the National Institute of Mental Health (NIMH). “We really don’t appreciate the importance of light in our … Continue reading →

Journal Club: Sticky proteins play crucial role in tailoring synapses

Posted on August 13, 2018 by Charlotte Schubert

The proteins that join neurons together at the synapse do more than just act like glue. Synaptic adhesion proteins are known to affect the activity of neurotransmitters, weaken or strengthen synaptic connections, or direct where synapses form. Faulty adhesion proteins … Continue reading →

Journal Club: Giving the brain something to do highlights the circuitry of smarts

Posted on July 27, 2018 by Amber Dance

Scientists conducting neuroimaging studies hope that their MRI scans will offer up patterns that predict traits related to intelligence, personality, disease, or even offer insights into a patient’s clinical symptoms or their chances of responding to a drug. But according … Continue reading →

Journal Club: Microglial protein trafficking could play a role in neurodegenerative disorders

Posted on July 16, 2018 by Jyoti Madhusoodanan

Neurodegenerative conditions such as Alzheimer’s disease (AD) or Parkinson’s are associated with a build-up of insoluble, toxic forms of proteins such as amyloid or tau in the brain. Normally, intracellular protein complexes known as retromers help with recycling and trafficking … Continue reading →

Journal Club: Mouse microbiome findings offer insights into why a high-fat, low-carb diet helps epileptic children

Posted on June 28, 2018 by Carolyn Beans

For nearly a century, doctors have found that a strict high-fat, low-carbohydrate diet can limit seizures in children with epilepsy when medications fail. But exactly how this ketogenic diet works has remained largely a mystery. Now, researchers at the University … Continue reading →

Journal Club: Proprioceptive neurons offer new insights into a “sixth sense”

Posted on June 25, 2018 by Jessica P. Johnson

Proprioception allows people to know the position of parts of the body without seeing them, enabling us to touch type, walk in the dark without falling over, or drive a car while looking at the road. Defects in this sensory … Continue reading →

Journal Club: Fruit flies’ internal circadian clocks continually check the temperature

Posted on March 2, 2018 by Amber Dance

As a fruit fly sails from sunshine into a patch of shade, its temperature drops by 10 degrees F or so. Immediately, certain neurons in its brain spring into action, telling the fly’s circadian clock about the temperature change. By … Continue reading →

Journal Club: New clues in the mystery of the mechanism of general anesthetics

Posted on January 26, 2018 by Jessica P. Johnson

Anesthetics have been used in surgery since the mid-1800s, but their exact mechanisms of action continue to be the subject of intense investigation. Past studies have suggested they block neurotransmitter receptors postsynaptically. Now a new study, published January 9 in … Continue reading →

Journal Club: New technique lights up the connectome, tracking signals across neuronal populations

Posted on December 21, 2017 by Amber Dance

Neuroscientists still possess an incomplete understanding of how different neurons interface and communicate throughout the brain’s wiring diagram, called the connectome. In a recent eLife article, Caltech molecular neurobiologist Carlos Lois and colleagues introduce a new tool to screen for such … Continue reading →
