Journal Club: Key protein family helps govern sense of touch in both plants and animals

Posted on November 16, 2018 by Amber Dance

Compared to their knowledge of other senses, scientists know relatively little about how cells sense touch. A newly confirmed family of mechanosensors, comprising more than a dozen members and present in both plants and animals, is an important step toward … Continue reading →

Journal Club: Researchers catch the mouse brain in the act of learning something new

Posted on November 5, 2018 by Amber Dance

Neurobiologists have captured, for the first time, the moment in a mouse’s brain when it first learns something new: in this case, that a beep signals a delicious droplet of sugar water. The results, recently reported in Nature Neuroscience, support a famous … Continue reading →

Journal Club: Simple model reproduces patterns of toxic protein buildup across multiple neurodegenerative diseases

Posted on October 26, 2018 by Jessica P. Johnson

Fatal neurodegenerative diseases including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS) begin as tiny pockets of misfolded proteins that evade the body’s normal detritus-removal systems. They spread throughout the brain and clog neural pathways. But exactly how these proteins propagate … Continue reading →

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 →
