Projecting a visual image directly into the brain, bypassing the eyes

Projecting a visual image directly into the brain, bypassing the eyes | Salud Publica | Scoop.it
Imagine replacing a damaged eye with a window directly into the brain — one that communicates with the visual part of the cerebral cortex by reading from a million individual neurons and simultaneously stimulating 1,000 of them with single-cell accuracy, allowing someone to see again.

That’s the goal of a $21.6 million DARPA award to the University of California, Berkeley (UC Berkeley), one of six organizations funded by DARPA’s Neural Engineering System Design program announced this week to develop implantable, biocompatible neural interfaces that can compensate for visual or hearing deficits.*

The UCB researchers ultimately hope to build a device for use in humans. But the researchers’ goal during the four-year funding period is more modest: to create a prototype to read and write to the brains of model organisms — allowing for neural activity and behavior to be monitored and controlled simultaneously. These organisms include zebrafish larvae, which are transparent, and mice, via a transparent window in the skull.

 

“The ability to talk to the brain has the incredible potential to help compensate for neurological damage caused by degenerative diseases or injury,” said project leader Ehud Isacoff, a UC Berkeley professor of molecular and cell biology and director of the Helen Wills Neuroscience Institute. “By encoding perceptions into the human cortex, you could allow the blind to see or the paralyzed to feel touch.”

 

To communicate with the brain, the team will first insert a gene into neurons that makes fluorescent proteins, which flash when a cell fires an action potential. This will be accompanied by a second gene that makes a light-activated “optogenetic” protein, which stimulates neurons in response to a pulse of light.

 

To read, the team is developing a miniaturized “light field microscope.” Mounted on a small window in the skull, it peers through the surface of the brain to visualize up to a million neurons at a time at different depths and monitor their activity. This microscope is based on the revolutionary “light field camera,” which captures light through an array of lenses and reconstructs images computationally in any focus.

 

The combined read-write function will eventually be used to directly encode perceptions into the human cortex — inputting a visual scene to enable a blind person to see. The goal is to eventually enable physicians to monitor and activate thousands to millions of individual human neurons using light.

 

Isacoff, who specializes in using optogenetics to study the brain’s architecture, can already successfully read from thousands of neurons in the brain of a larval zebrafish, using a large microscope that peers through the transparent skin of an immobilized fish, and simultaneously write to a similar number.

 

The team will also develop computational methods that identify the brain activity patterns associated with different sensory experiences, hoping to learn the rules well enough to generate “synthetic percepts” — meaning visual images representing things being touched — by a person with a missing hand, for example. This technology has a lot of potential in the future.

Nuevas clasificaciones de los países según su nivel de ingreso: 2017-18

Los datos actualizados de las clasificaciones de los países por nivel de ingreso del Banco Mundial para el ejercicio 2018 se encuentran disponibles aquí. (i) El Banco Mundial clasifica las economías del mundo en cuatro grupos de ingreso: alto, mediano alto, mediano bajo y bajo. Esta clasificación se basa en el ingreso nacional bruto (INB) per cápita calculado según el método Atlas. (i) Las unidades para esta medida y para los umbrales son en dólares corrientes de los Estados Unidos. En el Banco, estas clasificaciones se usan para agregar datos de grupos de países similares. (i) La categoría de ingreso de un país no es uno de los factores usados que influyen en la toma de decisiones en materia de financiamiento. Cada 1 de julio, actualizamos las clasificaciones. Estas cambian por dos razones: En cada país, factores como el crecimiento del ingreso, la inflación, los tipos de cambio y los cambios demográficos influyen en el INB per cápita. Para mantener los límites en dólares, que separan las clasificaciones fijadas en términos reales, los ajustamos de acuerdo a la inflación. Los datos para el primer ajuste provienen de las estimaciones del INB per cápita de 2016, que se encuentran ahora disponibles. (i) Este año, los umbrales han descendido levemente debido a la disminución de la inflación y al fortalecimiento del dólar estadounidense. Cliquee aquí (i) para obtener más información sobre cómo el Banco Mundial determina la clasificación de los países. Datos actualizados de los umbrales Los nuevos umbrales se determinan al inicio del ejercicio del Banco en el mes de julio y permanecen fijos por un periodo de 12 meses, independientemente de las revisiones de las estimaciones que se realicen después. Al 1 de julio de 2017, los nuevos umbrales para la clasificación de los países según su nivel de ingreso son: .tg {border-collapse:collapse;border-spacing:0;} .tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg .tg-9hbo{font-weight:bold;vertical-align:top} .tg .tg-yw4l{vertical-align:top} Umbral INB per cápita (USD corrientes) Ingreso bajo 1005 o menos Ingreso mediano bajo entre 1006 y 3955 Ingreso mediano alto entre 3956 y 12 235 Ingreso alto 12 235 o más Cambios en la clasificación Los siguientes países pertenecen a nuevos grupos de ingreso: .tg {border-collapse:collapse;border-spacing:0;} .tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;} .tg .tg-9hbo{font-weight:bold;vertical-align:top} .tg .tg-yw4l{vertical-align:top} País Antiguo grupo Nuevo grupo Angola Ingreso mediano alto Ingreso mediano bajo Croacia Ingreso alto Ingreso mediano alto Georgia Ingreso mediano alto Ingreso mediano bajo Jordania Ingreso mediano alto Ingreso mediano bajo Nauru Ingreso alto Ingreso mediano alto Palau Ingreso mediano alto Ingreso alto Samoa Ingreso mediano bajo Ingreso mediano alto Tonga Ingreso mediano bajo Ingreso mediano alto En la página de grupos de países y financiamiento (i) se proporciona una lista completa de las economías clasificadas por ingreso, región y situación crediticia, y enlaces a las clasificaciones de los años anteriores. Las tablas de clasificación incluyen a todos los miembros del Banco Mundial, además de todas las otras economías con poblaciones superiores a 30 000 habitantes. Los términos país y economía se usan indistintamente y no implican independencia política, pero se refieren a cualquier territorio cuyas autoridades presentan estadísticas sociales o económicas en forma independiente. Las tablas que muestran los datos del INB, (i) INB per cápita, (i) GDP, (i) PIB PPA (i) y población (i) de 2016 están también disponibles en el catálogo de datos de libre acceso del Banco Mundial.

New microscope can scan tumors during surgery and examine cancer biopsies in 3-D

New microscope can scan tumors during surgery and examine cancer biopsies in 3-D | Salud Publica | Scoop.it

When women undergo lumpectomies to remove breast cancer, doctors try to remove all the cancerous tissue while conserving as much of the healthy breast tissue as possible. But currently there’s no reliable way to determine during surgery whether the excised tissue is completely cancer-free at its margins — the proof that doctors need to be confident that they removed all of the tumor. It can take several days for pathologists using conventional methods to process and analyze the tissue.

 

That’s why between 20 and 40 percent of women have to undergo second, third or even fourth breast-conserving surgeries to remove cancerous cells that were missed during the initial procedure, according a recent study. 

 

The new light-sheet microscope — which is described in a new paper published June 26, 2017 in Nature Biomedical Engineering — offers other advantages over existing processes and microscope technologies. It conserves valuable tissue for genetic testing and diagnosis, quickly and accurately images the irregular surfaces of large clinical specimens, and allows pathologists to zoom in and “see” biopsy samples in three dimensions.

 

“The tools we use in pathology have changed little over the past century,” said co-author Nicholas Reder, chief resident and clinical research fellow in UW Medicine’s Department of Pathology. “This light-sheet microscope represents a major advance for pathology and cancer patients, allowing us to examine tissue in minutes rather than days and to view it in three dimensions instead of two — which will ultimately lead to improved clinical care.”

Researchers Identify Liver Fibrosis-Causing Protein

Researchers Identify Liver Fibrosis-Causing Protein | Salud Publica | Scoop.it

An international team of scientists has identified a long-sought protein that causes liver fibrosis (scarring), paving the way for new treatments. The research was published in the journal Nature Genetics.

 

The team led by Professor Jacob George and Dr. Mohammed Eslam of the Westmead Institute for Medical Research in Sydney, Australia, has unequivocally shown that variations in the interferon lambda 3 (INLF3) protein are responsible for tissue damage in the liver.

 

The researchers had previously identified that the common genetic variations associated with liver fibrosis were located on chromosome 19 between the IFNL3 and IFNL4 genes.

 

In the new study, they analyzed liver samples from 2,000 patients with hepatitis C, using state-of-the art genetic and functional analysis, to determine the specific IFNL protein responsible for liver fibrosis. They demonstrated that following injury there is increased migration of inflammatory cells from blood to the liver, increasing IFNL3 secretion and liver damage.

 

Notably, this response is determined to a great extent by an individual’s inherited genetic makeup. “This was a significant outcome that will help to predict risk of liver disease for individuals, enabling early intervention and lifestyle changes,” said Prof. George, who is the corresponding author of the study.

 

“We have designed a diagnostic tool based on our discoveries, which is freely available for all doctors to use, to aid in predicting liver fibrosis risk. This test will help to determine whether an individual is at high risk of developing liver fibrosis, or whether a patient’s liver disease will progress rapidly or slowly, based on their genetic makeup. This important discovery will play a vital role in reducing the burden of liver disease into the future,” he said. “This discovery holds great promise for the development of effective therapeutic treatments for liver disease,” added co-lead author Dr. Eslam.

 

“There is an urgent need for a safe pharmacologic therapy that can prevent of regress the progression of liver damage. There are currently no treatments available for patients with advanced fibrosis, and liver transplantation is the only treatment for liver failure,” he said. “Now that we’ve identified IFNL3 as the cause of liver scarring, we can work towards developing novel treatments specifically targeting this gene. This could be medicine targeting IFNL3 that is tailored to an individual’s genetic makeup, but could also include modifying usual treatment depending on whether a patient has IFNL3 risk genes.”

15 health and wellness use cases for virtual reality

15 health and wellness use cases for virtual reality | Salud Publica | Scoop.it
Virtual reality has moved from science fiction to marketable consumer product astonishingly quickly, partly because the incorporation of the smartphone into the technology makes it accessible, if not ubiquitous. It’s looking more and more like those who bet that virtual reality is here to stay, and not a flash-in-the-pan trend, made the smart bet.
 
But what about in healthcare? Could a technology primarily associated with gaming turn out to be a serious therapeutic tool? Well, a growing number of doctors, researchers, and entrepreneurs think it can. Some are even starting to collect efficacy data to that effect. In May, Kalorama reported that the virtual and augmented reality market in healthcare grew from $525 million in 2012 to an estimated $976 million in 2017.
