Better Memory through Electrical Brain Ripples

2019-06-29T20:22:30-04:00June 16th, 2019|

News article about Antonio’s study in Scientific American by Simon Makin Specific patterns of brain activity are thought to underlie specific processes or computations important for various mental faculties, such as memory. One such “brain signal” that has received a lot of attention recently is known as a “sharp wave ripple”—a short, wave-shaped burst of high-frequency oscillations. Researchers originally identified ripples in the hippocampus, a region crucially involved in memory and [...]

New book by György Buzsáki

The Brain from Inside Out Buzsáki, G. The Brain from Inside Out. Oxford University Press (May 2019) [Amazon] Is there a right way to study how the brain works? Following the empiricist’s tradition, the most common approach involves the study of neural reactions to stimuli presented by an experimenter. This ‘outside-in’ method fueled a generation of brain research and now must confront hidden assumptions about causation and concepts that may not hold neatly [...]

Our Stephanie’s community outreach efforts make waves

Series Combats Disorders: First Up, Epilepsy People with epilepsy were once thought to be possessed by demons or evil spirits. Dubbed “the sacred disease,” epilepsy was profoundly misunderstood for centuries, even after the disorder was explained to be of human origin. So why is it, so many years later, that epilepsy is still not fully understood? And why is there still so much stigma attached to a disorder which affects [...]

Optogenetics/Brain Research: Optical developments take optogenetics deeper, less invasively

2018-12-03T21:07:05-04:00December 3rd, 2018|

Optogenetics has rocked the world of neuroscience for more than a decade now. But neuroscientists want more from the technique—and less, including more depth and less invasiveness. As neuroscientists progress in their application of optogenetics, they want to take it further. This is evidenced by an explosion in the development of light-sensitive opsins that allow researchers to target neurons with amazing specificity. The result has been an explosion in understanding the relationships between [...]

The Time Debate: The Neurons That Tell Time

2018-12-03T16:41:20-04:00December 3rd, 2018|

In June of 2007, Albert Tsao, a nineteen-year-old native of Silver Spring, Maryland, was working in Trondheim, Norway, at the Kavli Institute for Systems Neuroscience. Tsao was a summer intern in the lab of May-Britt and Edvard Moser, married researchers who were well known in neurobiology circles for discovering “grid cells”—neurons that, by tracking our position, create a navigational map in the brain. Grid cells are located in an area of the brain [...]

Cuba ‘sonic attack’ conspiracy theories and flawed science

2018-06-08T14:18:05-04:00June 1st, 2018|

Science works best when qualified people can evaluate evidence without political pressure to draw poorly founded conclusions, say 15 neuroscientists and physicists. Read the full story below or at theguardian.com As neuroscientists and physicists we have no reason to dispute that US diplomats living in Cuba heard loud noises, or that they reported feeling ill afterwards. Some US politicians have seized on these reports to construct conspiracy theories in which they imagine a mysterious disease-causing “sound [...]

Cross-Species Neuromodulation from High-Intensity Transcranial Electrical Stimulation

2018-04-01T20:33:59-04:00March 31st, 2018|

Review article in Trends in Cognitive Sciences about our recent paper, by Alik S. Widge Transcranial electrical stimulation (TES) is a proposed tool for non-invasively modulating human brain circuits, but its ability to affect cortical physiology remains unclear. A recent study merged TES with live animal and human cadaveric recordings to verify intracranial electrical effects, then used these findings to develop a novel neuro-modulation protocol.
