SINDROME DE VIBRACION FANTASMA POR EL CELULAR

Vibración Fantasma

La vibración fantasma, un fenómeno muy extendido

El 80% de los usuarios sufrimos el síndrome de la vibración fantasma, que no es otra cosa que esas falsas alarmas en las que creemos que nuestro móvil ha vibrado cuando en realidad no lo ha hecho. Pero lo más curioso es que hasta un 30% de la población también escucha llamadas fantasma.

Según los expertos las vibraciones fantasma son inevitables. Se trata de un fenómeno natural y muy sano de nuestro cerebro que evidencia cómo percibe nuestro alrededor.

“Síndrome de la vibración fantasma”, un nombre acuñado por un grupo de neurólogos de varias universidades norteamericanas, cuyas investigaciones se basaron en estudiar la sensación que sienten muchas personas que creen que su móvil ha vibrado y se apresuran a mirar quién les ha llamado o enviado un mensaje.

Lo curioso del caso es que esto ocurre en infinidad de ocasiones en el que no se lleva el teléfono encima o incluso estando éste apagado, llegando a ser comparado con el “Síndrome del miembro fantasma”, del que ya os hablé hace unos meses y que padece un gran número de personas amputadas, que sienten picor o dolor en el miembro que ya no tienen.

El hecho de que a una persona le ocurra el Síndrome de la vibración fantasma es debido a la costumbre que ha adquirido de estar continuamente recibiendo llamadas y/o mensajes a lo largo del día y esto hace que la parte de su cuerpo que normalmente está en contacto con el móvil perciba esa ‘vibración fantasma’, a pesar de no estar recibiendo ninguna llamada en ese momento. Lo mismo ocurre con el oído, el cual es capaz de escuchar el peculiar sonido de la vibración sin que esté sonando.

Las vibraciones fantasmas del celular también pueden explicarse por la "neuroplasticidad" — es la capacidad del cerebro para las nuevas conexiones en respuesta a cambios en el medio ambiente.

Pero Rob Whitehouse, vice presidente de comunicaciones en un hospital universitario, insiste en que las vibraciones fantasmas que experimenta cada día son simplemente una prueba constante de cuán importante son las comunicaciones.

"Es alguna expresión psicológica de mi necesidad de siempre estar conectado", dice. "Es como cuando recivimos nuestro primer correo electrónico, y verificamos constantemente nuestras bandejas de entrada, porque la obtención de un nuevo mensaje fue una sensación muy emocionante.

La Nueva Tecnología y el Cerebro

Nuestro Cerebro Va Cambiando de un Momento a Otro

Cuando miramos la pantalla de una computadora cada estímulo sensorial provoca una respectiva reacción química en el cerebro

Estos estímulos cerebrales provocan respuestas fisiológicas:

_ Luz hacia el ojo

_ Neurotransmisores/reacciones químicas mediante el nervio óptico

_ Los mensajes viajan a lo largo de redes neuronales

Organización de la Red Neuronal

El cerebro pesa sólo Only 3 lbs

1,000,000,000,000,000 synapses

The Specialized Brain Perception of Image or Sensation

_ Stir intense emotional reactions

_ Jog repressed memories

_ Trigger an automatic response

New Technology and the Brain

_ Changing our lives and our BRAINS

_ Young person’s brain most sensitive and most exposed

_ digital natives

_ digital immigrants

_ Bridging the brain gap

Brain Plasticity

_ Like a new computer

_ Basic programs built-in

_ Plenty of room on hard-drive for new info

_ Specialized circuits (computer “macros”)

_ “weaken” when not used

Malleable Young Brains

_ Upside – learning is fast

_ Languages

_ Musical instruments

_ Downside – still a lot to learn

_ Frontal lobe

_ Amygdala

_ By adolescence, 60% of

synapses are trimmed

away or “pruned”

Cascade of Events

_ Discovery of hand-held tool, handedness

_ Enlarged frontal lobe, goal-directed behavior

_ Grammatical language, social networking

Natural Selection

_ Charles Darwin

_ Genetic variants that adapt best to environment, most likely to survive

As Our Environment Changes, Our Brains Adapt

Is the environment really changing?

Young people between age 8 and 18 put in a total of how much tech time (computer, TV, etc.) each day?

_ 4 hours

_ 6 hours

_ 11.5 hours

_ 8 hours

DIGITAL NATIVES:

_ Born into technology

_ 24/7 use and access

_ More technology, less direct, face-to-face social interaction

_ Brains still developing

_ Empathy, complex reasoning skills

_ Technology is not only changing our lives, it’s changing our BRAINS now and will in the future

_ The new generation gap is a brain gap

_ We can find balance in our lives and bridge the brain gap

_ by improving technology and social skills

_ knowing when to use them
