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 →

Future choices may be guided by our memories of past ones

Posted on July 17, 2020 by Jill Sakai

When it comes to making choices, past decisions may play a surprisingly large role. The traditional view of decision-making is that our choices are guided by what we remember about the outcomes of previous choices we’ve made. But in recent … Continue reading →

Dopamine-making neurons, an ongoing mystery, play a bigger role in reinforcing learning than in initiating action

Posted on January 24, 2020 by Amber Dance

Deep in the midbrain, one type of neuron has two crucial jobs when it comes to acting while anticipating a reward—a state also known as Pavlovian conditioning. Called dopaminergic (DA) neurons, they can link a signal, such as a sound … Continue reading →

Journal Club: Neurons fire in sync, helping elucidate the biological basis of learning

Posted on May 17, 2019 by Amber Dance

Our brains change as we learn. But how exactly does a cluster of neurons change their activity or connections? It seems the phenomenon is due, at least in part, to neurons starting to fire in sync, according to a recent … 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 →
