Memory Researchers Link Two Brain Regions to Conceptual Organization

Memory Researchers Link Two Brain Regions to Conceptual Organization | Necesidad de saber | Scoop.it
A long debate has existed in psychology whether concepts, such as a dog, are represented in the mind as a collection of specific dogs that people have encountered or whether individuals can abstract the key characteristics across specific examples to form a generalized idea, or prototype, of a dog.

Without knowing all the dogs someone has seen before, it may be difficult to tell whether people can recognize a new animal as a dog because they rely on a comparison to specific dogs or rather their prototype.

Knowing more about the ability to build abstract memories, the researchers said, could help educators develop new strategies for teaching concepts.

In an experiment aimed to uncover how concepts are represented in the brain, 29 participants, ages 18-28, first viewed several novel cartoon animals as examples from two different concept categories whose members were related to families called Romeo or Juliet. Researchers then used functional MRI to watch the brains of participants as they viewed new, previously unseen cartoon animals and chose which family was the best match for each.

Responses revealed that participants must have formed and relied on abstract representations – the prototypes — of the new concepts, reported Caitlin Bowman and Dagmar Zeithamova of the UO’s Department of Psychology in the March 7 issue of the Journal of Neuroscience.

The fMRI data allowed them to follow processing across the brain as decisions were made. They documented activity in the anterior hippocampus and ventromedial prefrontal cortex that was consistent with a retrieval of the prototype rather than specific concept examples. This finding suggests the hippocampus — previously considered a filing system for specific memories of individual events — has a role in conceptual memory formation.

You Can Hack Almost Any Smart Device With A Google Search

You Can Hack Almost Any Smart Device With A Google Search | Necesidad de saber | Scoop.it
Thirty minutes. That’s the time it took a team of researchers from Ben-Gurion University in Israel to access security cameras, baby monitors, doorbells, thermostats, and other internet-of-things, not-so-smart devices. It didn’t require any special hacking techniques. Anyone can do it.

The only tools you need are at least one finger–a nose will work too–to type the brand and model of whatever device you want to hack, and a connected web browser. Put that information into a Google search box and, within a few minutes, you will find a site or a forum post somewhere describing how to enter into that device using the manufacturer’s default administration user name and password. Any pedophile, thief, ex-spouse, or regular Peeping Tom can use this information to gain access to any of these devices installed in your home. A government or criminal organization can also use these user/password combos to control many devices at once, in order to mine data, spy, or launch global internet attacks.

'Memtransistor' Forms Foundational Circuit Element to Neuromorphic Computing

'Memtransistor' Forms Foundational Circuit Element to Neuromorphic Computing | Necesidad de saber | Scoop.it
Computers that operate more like the human brain than computers—a field sometimes referred to as neuromorphic computing—have promised a new era of powerful computing.

While this all seems promising, one of the big shortcomings in neuromorphic computing has been that it doesn’t mimic the brain in a very important way. In the brain, for every neuron there are a thousand synapses—the electrical signal sent between the neurons of the brain. This poses a problem because a transistor only has a single terminal, hardly an accommodating architecture for multiplying signals.

Now researchers at Northwestern University, led by Mark Hersam, have developed a new device that combines memristors—two-terminal non-volatile memory devices based on resistance switching—with transistors to create what Hersam and his colleagues have dubbed a “memtransistor” that performs both memory storage and information processing.

This most recent research builds on work that Hersam and his team conducted back in 2015 in which the researchers developed a three-terminal, gate-tunable memristor that operated like a kind of synapse.

EL TREN DE VILLAGARCÍA (Un artículo de Julio Camba)

No bien asumió el Poder, el Gobierno provisional de la República empezó a suspender diarios de gran circulación, y, si se tiene en cuenta que casi todos los ministros procedían del periodismo, habrá que comparar este hecho histórico con el de Hernán Cortés, cuando, en su propósito de no abandonar jamás ni un palmo del territorio que conquistase, quemó todas sus naves al llegar a Méjico.

Slow and Steady Waves Keep Brain Humming

Slow and Steady Waves Keep Brain Humming | Necesidad de saber | Scoop.it
If you keep a close eye on an MRI scan of the brain, you’ll see a wave pass through the entire brain like a heartbeat once every few seconds. This ultra-slow rhythm was recognized decades ago, but no one quite knew what to make of it. MRI data are inherently noisy, so most researchers simply ignored the ultra-slow waves.

But by studying electrical activity in mouse brains, researchers at Washington University School of Medicine in St. Louis have found that the ultra-slow waves are anything but noise. They are more like waves in the sea, with everything the brain does taking place in boats upon that sea. Research to date has been focused on the goings-on inside the boats, without much thought for the sea itself. But the new information suggests that the waves play a central role in how the complex brain coordinates itself and that the waves are directly linked to consciousness.

“Your brain has 100 billion neurons or so, and they have to be coordinated,” said senior author Marcus Raichle, MD, the Alan A. and Edith L. Wolff Distinguished Professor of Medicine and a professor of radiology at Mallinckrodt Institute of Radiology at the School of Medicine. “These slowly varying signals in the brain are a way to get a very large-scale coordination of the activities in all the diverse areas of the brain. When the wave goes up, areas become more excitable; when it goes down, they become less so.”

¿Convendría una asignatura de pensamiento crítico?

Hace unos días, un amigo me invitó al colegio donde trabaja para que explicase a un grupo de chicos y chicas de 16 a 18 años cómo se hace un programa de televisión. La charla, sin embargo, no tardó en centrarse en un solo asunto. Ocurrió cuando dejé caer que los medios de comunicación raramente dicen "la verdad". Que, de hecho, lo único que podemos considerar "verdad" son los datos en que se basa una noticia; a partir de ahí todo es interpretación, ideología, sesgo y, en algunos casos, también mentira malintencionada.
Félix Santamaria's insight:
El pensamiento crítico es intrínsecamente opuesto a la noción de asignatura. Es una forma de concebir las relaciones en todos los dominios de la vida, incluida la del aula.

El Pensamiento Crítico en el aula

El Pensamiento Crítico en el aula | Necesidad de saber | Scoop.it

Nel Noddings, profesora de la Universidad de Stanford, plantea en su libro Filosofía de la Educación [1] que “los filósofos y los educadores coinciden, desde hace mucho tiempo, en la importancia del Pensamiento Crítico; pero no han podido ponerse completamente de acuerdo sobre en qué consiste y mucho menos concuerdan en cómo enseñarlo”.

 

El criterio anterior se ha modificado a partir de la convocatoria de un amplio panel de expertos, provenientes de muchas disciplinas académicas, que se reunió prolongadamente, durante los años 1988 y 1989, para discutir qué es el Pensamiento Crítico. Como resultado del consenso alcanzado en ese panel se publicó “El Informe Delphi” (The Delphi Report) [2]. En ese informe se definió el Pensamiento Crítico como “el juicio auto regulado y con propósito que da como resultado interpretación, análisis, evaluación e inferencia; como también la explicación de las consideraciones de evidencia, conceptuales, metodológicas, criteriológicas o contextuales en las cuales se basa ese juicio. El Pensamiento Crítico es fundamental como instrumento de investigación. Como tal, constituye una fuerza liberadora en la educación y un recurso poderoso en la vida personal y cívica de cada uno. Si bien no es sinónimo de buen pensamiento, el Pensamiento Crítico es un fenómeno humano penetrante, que permite auto rectificar”.

 

Adicionalmente, en ese mismo informe se definió al pensador crítico ideal como “una persona habitualmente inquisitiva; bien informada, que confía en la razón; de mente abierta; flexible; justa cuando se trata de evaluar; honesta cuando confronta sus sesgos personales; prudente al emitir juicios; dispuesta a reconsiderar y si es necesario a retractarse; clara respecto a los problemas o las situaciones que requieren la emisión de un juicio; ordenada cuando se enfrenta a situaciones complejas; diligente en la búsqueda de información relevante; razonable en la selección de criterios; enfocada en preguntar, indagar, investigar; persistente en la búsqueda de resultados tan precisos como las circunstancias y el problema o la situación lo permitan”.

How Women Experience Addiction Differently Than Men

How Women Experience Addiction Differently Than Men | Necesidad de saber | Scoop.it

Addiction to substances such as heroin and alcohol affect women differently than men. A 2010 American Journal of Public Health study found that women were more likely to be prescribed opioids than men and to continue them long-term. Another study of chronic pain patients prescribed opioids in the Journal of Pain revealed that women’s increased risk of opioid misuse was related to emotional issues while men misused opioids because of legal and behavioral problems.

 

According to the Centers for Disease Control and Prevention (CDC), women are more likely to have chronic pain, be prescribed prescription painkillers and at higher doses than men; and become dependent more quickly than men. From 1999 to 2010, CDC data revealed that 48,000 women died of prescription-related overdoses. During this timeframe, prescription overdose deaths increased over 400% among women, versus 237% among men. The sobering statistics don’t end with prescriptions. The National Center for Health Statistics reported heroin overdose deaths among women tripled from 2010 through 2013.
