Rachel Skipper -- I am a graduate student in IU’s Department of Psychological & Brain Sciences and the Program in Neuroscience. I have always been interested in how experiences can affect the brain and how that, in turn, affects behavior. My current research focuses on the effects of stress; specifically, I am interested in how stress shapes learning and memory. This is probably something that all scientists and students are familiar with! I look forward to talking with ScIU readers about this and other neuroscience research at IU.

Teaching an old dog new tricks: Neuroscience research at IU combines centuries-old methods with modern technology

A photograph of a neuron (left panel) is shown next to an illustration of the same neuron (right panel). Left panel: The image background is brown. A single neuron is shown. The cell body is black and ovular, and dendritic branches look like sinuous lines extending from the cell body. A single dendrite extends from the top of the cell body, and multiple dendrites extend from the base. Right panel: A multicolor illustration of the neuron pictured in the left panel. The image background is black. The cell body and each dendritic tree is shown in a different color (dark blue, light blue, pink, green, and yellow). Parts of the dendritic tree that were out of focus in the left panel are clearly reconstructed in the right panel; the size and shape of each dendrite is otherwise identical between the two panels.

This post is the second installment in a two part series. Check out last week’s post here. Thanks to modern technology, the field of cellular neuroscience has become illuminated with brightly colored images – tissue samples, cells, and individual molecules have been stained, photographed, colorized, and even reconstructed in three dimensions.

Harnessing the therapeutic benefits of marijuana: Research findings from Dr. Andrea Hohmann’s laboratory at Indiana University presented at international neuroscience conference

Image of the brain surrounded by marijuana leaves

Last week, over 32,000 neuroscientists met in San Diego for the annual Society for Neuroscience (SfN) conference. Joining them were members of IU’s Program in Neuroscience, including Dr. Andrea Hohmann, who is also a professor in the Department of Psychological and Brain Sciences in the College of Arts in Sciences and a Linda and Jack Gill Chair of Neuroscience… Read more »

New research at IU explores links between gut microbiota and the brain

You might be surprised to learn that your body is home to tens of trillions of microorganisms. In fact, your body contains more microbes than it does human cells. While that might sound a bit worrisome, these tiny, single-celled organisms are extremely important for human health. For example, the microbes that live in the gut… Read more »
