UMass Neurosciences Publications – July 2019

This month’s featured researcher is the UMass Director of Neurosciences, Paul Katz. His lab studies the neural basis of behavior. Three of his recent papers appeared in PubMed this month.  His recent commentary in Current Biology explores how often Life Scientists display a bias in their choice of experiments and their understanding of evolution. His work shows that different levels of biological organization undergo separate evolutionary history. In particular, his recent Journal of Neuroscience paper showed that the same neuron in different species have dramatically different functions in neural circuits that produce the same behavior. Another paper, published in the Proceedings of the Royal Academy, which appeared in PubMed this month showed convergent evolution of neural circuits and behaviors.  Katz is leading a collaborative team of researchers from four universities that form the Berghia BRAIN project to use high throughput methods to study the neural basis of behavior in a sea slug.

Here’s what else is new for ‘ ”University of Massachusetts” AND Amherst AND neuroscience’ in PubMed. These publications appeared on line in July. They are just a fraction of the research that occurs on campus. Continue reading

IONs Director’s Channel – July 2019

Paul Katz and Luke Remage-Healey at the NSB picnic enjoying a special dessert.

It’s summer and the fun never ends. We’re really pleased to hear that Dr. Ilea Karatsoreos has accepted a faculty position in Psychological and Brain Sciences. That further strengthens the great group of neuroendocrinologists at UMass.  Research is going strong across campus, which you can read about here. The Neuroscience Summer Seminar Series is in full swing. It’s been a great opportunity to learn about the research on campus. If you’re looking for other things to do this summer besides enjoying the beautiful weather in the valley, go cheer the NSB grad student softball team, Spikes ‘n Strikes.

 

UMass researchers find sex differences in cognition of middle-aged marmosets

In a paper recently published in the journal e-Neuro, NSB doctoral recipient Matthew LaClair and his advisor Agnes Lacreuse, examined what is a highly controversial topic in humans, by turning to the nonhuman primate, the common marmoset. The investigators asked whether biological sex modulates some aspects of cognitive performance as well as neural connectivity measures. They identified sex differences in cognitive flexibility that are correlated with sex-dependent patterns of resting brain networks.  The findings support the idea that cognitive sex differences may have identifiable intrinsic neural correlates. Investigating the dynamics of cognitive sex differences and associated brain networks across the lifespan may shed a new light on sex-specific cognitive disorders. Continue reading
