This week in class we read about a telescope "brain", the human brain, artificial neural networks and the conventional computer. I asked you if you thought all living things had a brain and if the ameba had one too. Let´s see.In this link you will find several living creatures. Which of them have a brain and what is the situation with the ameba (does it have a brain or just neurons according to this text?)
Are there certain animals that seem to have neurons but no brain?
How about the information in this disturbing article of an ameba that can EAT our brain! Here you will find another one that describes how researchers are trying to create living neural networks.
Write some answers or your reactions in the comment area of this post.

No realize el experimento...estava estudiando física pero si lei el contenido del link me parecio interesante que el cerebro del pulpo tiene 300.000.000 millones de neuronas.

I read the two text. I believe that the ameba has just neurons, because the text describe the ameba like a single-celled animal.

The Ameba has a different system, it doesn't have a brain because they are single-celled and this cell is in charge of directing all the vital functions.
About the article of the ameba who eats brains it is certainly disturbing, It's hard to imagine that things like that can really happen. The symptoms of the infection caused by this specie of ameba are very common in lot's of illnesses which makes it difficult to detect the problems on time.
I hope doctors find a way to prevent people from this dangerous ameba and eventually eliminate it.

I think this articules are good... everybody must had read about this in hihg school's biology!.
I think that the octopus is amazing because it have a good memory. I saw this earlier in a documentary program of national geographic... so interesting. The octopus remembered colors and shapes.
In the other articule about the ameba that can destroy our brain says that the infection caused by the ameba can be contracted in warm water, but what happens if we go to hot springs? are we at risk of becoming infected?... I don't stay clear.

Buenas profe, lei el link sobre la ameba que se come el cerebro, y de verdad es bastante asqueroso, para empezar eso de que entra por la nariz... luego todo lo que te da, el vomito, dolores de cabeza y demas, espero nunca pasar por eso. aunque de verdad nunca me imagine que una ameba pudiera causar todo eso.
always they described the ameba says than "is an single-celled animal.." and more, but i never asked "the ameba have brain?" now i know than the ameba don't have brain... and not only that, It's terrifying know than the ameba can eat my brain... and more terrifying than not exists a tratment to resolve the problem... was important to read about it, now i will take precaution about the terrifying ameba
Que interesante esta información profe, no sabia que existía este parásito (ameba) y que pudiera ocasionar tantas cosas, ahora me da miedo bañarme en cualquiera de esas aguas jaja, y Guillermo a mi también me llamó mucho la intención lo del pulpo, sobre todo porque según lo que entendí pueden percibir formas, la intensidad del color y la textura a través de sus ojos, y también me pareció interesante la información de la estrellita, porque es raro saber que existan seres vivos sin cerebros y sobre todo que no se puedan moverse, pero bueno eso es parte de la vida
Great comments Guillermo L., Carlos F., Marie, Kevin, Ricardo, Nathalia and Ma. Fer B.
Nature is really amazing and there are so many creatures we know little about.
Your generation has the advantage of having the web as a source of invaluable knowledge (and sometimes a lot of garbage as well)
Cheers, Berta
It was very interesting... Nature is amazing, just thinking about animal without brain is surprising, and how intelligent are the octopuses, they control every cell in its body just with a such simple brain, they change colors and form to avoid they predators.

Muy interesante el articulo de la Ameba, si sabia de la existencia de este parasito unicecular, mas bien, otros generos relacionados con la ameba se localizan en los intestinos de los hombres y animales. Lo que me parecio interesante es que no sabia los sintomas que puede ocasionar este parasito.
When i read this first posted link i start making assumptions about the development of the course. This first article was really interesting because few people including me did't know about those microcelular bacterias and thier functions.
