UNIVERSITY OF CALIFORNIA – LOS ANGELES HEALTH SCIENCESPrintEmail App LOS ANGELES – Even the legendary filmmaker Orson Welles couldn’t have imagined such a plot twist. By showing Welles’s movie “Touch of Evil” to mice, Chinmay Purandare, PhD, and Prof. Mayank Mehta of UCLA have uncovered surprising and important new insights about how neurons form memories....

Wearable EEG Patch Measures Brain Activity
OCTOBER 25TH, 2022 CONN HASTINGS NEUROLOGY Researchers at Osaka University in Japan engineered a wearable electroencephalography (EEG) device that can measure brain activity, potentially letting clinicians monitor conditions such as depression or dementia. At present, assessing brain activity requires a trip to a facility with bulky and expensive equipment, making long-term monitoring difficult. This latest technology...

Measuring brain activity on the go
OSAKA UNIVERSITY IMAGE: IMAGE OF DRY-TYPE BIOELECTRODE AND THIN-FILM SENSOR SHEET CREDIT: ATTRIBUTION 4.0 INTERNATIONAL (CC BY 4.0) Osaka, Japan – Brain activity has traditionally been assessed using large and often expensive technology that has limited its use to specific clinical settings. Small wearable devices that can assess brain activity are hoped to improve the...

Similar patterns of brain activation and language selectivity found in speakers of 45 different languages
by Anne Trafton, Massachusetts Institute of Technology Credit: Unsplash/CC0 Public Domain Over several decades, neuroscientists have created a well-defined map of the brain’s “language network,” or the regions of the brain that are specialized for processing language. Found primarily in the left hemisphere, this network includes regions within Broca’s area, as well as in other parts...

Using light and sound to reveal rapid brain activity in unprecedented detail
by Michaela Kane, Duke University The image shows the vasculature of the brain, and the colors illuminate how capillaries experience varying levels of oxygenation as the brain undergoes hypoxia.

Enzyme prevents brain activity from getting out of control
by University of Bonn Plasticity of neuronal communication elicited by 48-hour blockade of neuronal activity correlates with the number of RIM molecular clusters in the active zone. Column A is imaged with widefield illumination; column B is imaged with dStorm microscopy; column C shows molecular clusters. Credit: © Group Schoch McGovern Our bodies have the...

Scientists see what research participants picture in their mind’s eye
Researchers from Osaka University find that the meaning of an imagined image can be inferred from the pattern of a person’s brain activity, even if it differs from the image that the person is looking at. They say a picture is worth a thousand words. Now, researchers from Japan have found that even a mental...

New window system allows for long-term studies of brain activity
by Georgia Institute of Technology Bilal Haider and his tiny window. Credit: Jerry Grillo Bilal Haider is studying how multiple areas of the brain work together for visual perception. This could help researchers understand if neural activity “traffic jams” underlie all kinds of visual impairments: from running a red light when visual attention is elsewhere,...

Instability of brain activity during sleep and anesthesia underlies the pathobiology of Alzheimer’s disease
TEL-AVIV UNIVERSITY IMAGE: (LEFT TO RIGHT): PROF. INNA SLUTSKY, DANIEL ZARHIN AND REFAELA ATSMON. CREDIT: DR TAL LAVIV The researchers believe that low-arousal states such as sleep and anesthesia expose failures in a mechanism that regulates stability of brain activity in the early, pre-symptomatic stage of Alzheimer’s disease. This discovery paves the way to early...

Constant tinnitus is linked to altered brain activity
by Karolinska Institutet Graphical absract. Credit: DOI: 10.1172/JCI155094 There has to date been no reliable objective method of diagnosing tinnitus. Researchers from Karolinska Institutet now show that brainstem audiometry can be used to measure changes in the brain in people with constant tinnitus. The study has been published in the Journal of Clinical Investigation. Tinnitus is...
