Self Reflected: The Best of Neuroscience and Art

The phrase, “beauty is in the eye of the beholder” seems especially true for scientists. What we study becomes not only intellectually beautiful, but also literally beautiful: the form is pleasing to the eyes. Appreciation and endearment develops over time as scientists gaze on their subject for hours, days, years. In fact, research by the psychologist Robert Zajonc shows that the more familiar you are with something, the more likely you are to enjoy it.

Bite-size Science: Immune Cells use Neurotransmitter to Communicate

Researchers have suspected for a few years that neurotransmitters like dopamine play a role in how the immune system functions. But they didn’t know how cells in the immune system would actually used dopamine. A paper published on July 12 of this year shows for the first time that cells in the immune system send dopamine to other cells to trigger them into action. This is just like how neurons use dopamine in the brain! Check out the infographic for a summary of the discovery!

Bite-size Science: Epigenetics help protect the aging brain

Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.

Weird Animal Brain: Octopus

The octopus almost reaches alien status when it comes to its brain and nervous system.  And yet, the differences can help us understand more about the human brain as well as unique solutions nature has come up with for difficult problems like camouflage.  Octopuses can see polarized light, but cannot see color.  However, their skin changes both color and texture to camouflage with the surroundings.Continue reading

Stimulating Neural Circuits with Magnetism

Brain stimulation might sound like some Frankensteinian demonstration from a Victorian science fair. But in reality, it is a contemporary technique making a huge impact in neuroscience by addressing a longstanding limitation of traditional methods for investigating human brain function. Such techniques, like EEG and fMRI, can only be used to infer the effects of a stimulus or task on brain activity, and not vice versa. For example, a scientist might use EEG to study the effect of a task like arm movement on brain activity, but how can one study the effect of brain activity on arm movement?Continue reading
