The hippocampus has brief but critical role in early task learning

Posted on September 4, 2020 by Amy McDermott

How the brain learns new tasks is among the biggest and oldest questions in neuroscience. A recent study in Nature Neuroscience offers a new, potentially key part of the answer: the dorsal hippocampus is involved in the earliest stages of … 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: 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: New roles found for protein key to neurotransmission

Posted on August 11, 2017 by Carolyn Beans

Scientists know many of the proteins that make neurotransmission possible, but they don’t have a handle on how all the pieces work together. “As someone who has studied the synapse for a long time, I still find it frustrating … Continue reading →

Journal Club: ATP could help proteins dissolve in cells, prompting a rethink about its function and evolution

Posted on May 27, 2017 by Jyoti Madhusoodanan

Adenosine triphosphate (ATP) is widely considered biology’s “energy currency”. A crucial player in cell function, it stores and releases energy for enzymatic reactions in its phosphate bonds. But cells typically hoard amounts of ATP several hundred-fold higher than that needed … Continue reading →
