OCEANA – Logbook – conference

Kids have the mic!

Kids of year 7 succeeded in their challenge: to give a talk in a auditorium with 150 persons in the audience, at AgroParisTech engineering school in Paris. The topic of the talk what: how the brain work, how to optimize learning?

may1

All gathered by groups of 2 or 3, talking about content of the OCEANA program, they had picked their subtopic:

may2

  • the brain, identity card,
  • What we don’t see with our eyes:
    • neurons and
    • glials cells,
  • the brain, this complex organ, how it works?
    • neurons get connected
    • neuronal path are created
    • nothing is fixed, the brain is plastic and we can learn all lifespan,
  • the brain, functioning:
    • multiples brain lobes and functions,
    • what regions of the brain are used when we want to cross the street?
  • the brain memorize, the brain learn: how to help memory? how to optimize it?
  • We need messenger, the 5 sense: student are testing perception with the audience. Can we treat information if the vision is blur?
  • We need to reactivate perceived information: children played the “kim game” with the audience,
  • At the end, children ask to the audience what they learned about the brain. Do to that, they use a “memory game” to challenge the audience memory, we learn only if we don’t have “stress, fear …” and when we are active in the learning process.

 

Well done kids!

 

Each of the group created a tool to illustrate the message that they wanted to give: model, film, comic, card game …

Bravo! again to the kids that elicited curiosity, involvement and participation from the audience. The feedack that they received showed that information was successfully transferred, new neuronal paths was created or consolidated for all.

 

We wish to thanks WaxYouth, Jérémie Chaligné that initiated the project, for his invitation. The class and each kids, by participating to this event, experienced talking in public, which is a skill must needed for their future.

Around the tale

 

About Mimi

Mimi is a glial cell of the brain, and more accurately it’s a microglia. She have to care about Louis a neuron, with the help of Astride, an astrocyte. Mimi is tired of her work and, one day, she decide to leave to search for the chef to talk with him about her need of holidays.

 

Lead from neuron to neuron following message that they receive, Mimi is living an amazing adventure. She assists to the birth of a neuron, heal another, attached by microbes, see some fireworks when neurons communicate and discover cells that she didn’t know about …

 

But, is she going to find this famous chef od the brain?

 

 

Scientific knowledge 

This story aim to illustrate some global notion of anatomy and physiology of the brain. Particularly, we are talking about:

  • Global shape of neurones (with a soma, an axon and dendrites)
  • Connection between neurons, and their networks
  • Adult neurogenesis
  • Transmission of the neural information: thanks to action potentials (electric) and neurotransmitters (chemical)
  • Myelin sheath and oligodendrocytes that play a role in its creation
  • Microglia, cells of the immune system of the brain
  • Astrocytes, with a role in nutrition and partipating to the creation and functioning of synapsis

 

Go to references for more information.

Mimi the microglia is the first character created by Cogni’Junior.

It’s a glial cell of the immune system traveling inside the brain and discovering how it works.

The tale was created in september 2013.

Mimi’s adventure developped in comics, with a target, this time, older.

We let you discover the adventure and hope that you will like it!

Mimi and the voluntary movement

 

 

Mimi explore the brain in a new adventure about the movement and its execution.

This story was written in the light of the interaction with Jennifer C. holding a disease called “cerebral motor infirmity” and wanting popularize her disease. We decided to give a full explanation of the motor system in a tale and to popularize about the disease on another support.

Adventures of Mimi :

Fronti, a neuron of the frontal cortex, is surprised that the order of movement that him and his colleagues sent to other neurons isn’t follow by confirmation of execution. He is a bit concerned. In the neighborhood, our friend Mimi the microglia decide to help to find where the movement order is blocked: she is going to follow the message to understand where the problem come from. She bring along with her in the journey another microglia, Boulie, pretty proud to “fear nothing”, but the journey will give hard time to this conception of herself.
 
From neurons who decide of movement in the brain to moto-neurons who manage the muscle directly, passing by all neurons that play a role in the creation of the action, Mimi is doing a exceptional trip fro mthe brain to the spinal cord. Along the adventure, she understand the importance of confirming order that are executed or not (via what we call “retro action loop” or feedback), and will discover the possibility of bypass in the brain, when a reflex happens.


Scientific knowledge :

 This story needs to be considered at a follow up of the first tale the adventures of Mimi (which present the basis to understand the functioning of the brain) aims to illustrate global notions of anatomis and physiologie o the nervous system related to movement, and to talk about pathology of movement. These pathology tend to induice misunderstanding and prejudices about disable people. We can sometimes think that they are cognitively disable but it’s not obligatory the case. Ths story is born after the proposition of Jennifer, that have cerebral motor infirmity, she contacted us because she wanted to popularize her disease.

For this aim, we present:

  • the different cerebral areas, neurons involved when we decide to do a movement and they different role
  • the moment when they are involved in the chain of action
  • the place where they are in the body (in the brain but also in the spinal cord for other).
  • the diference between involuntary movement, dignified in the brain and sent to concerned muscle, and a movement reflex.
  • the retro action loop and the importance of verifying constantly the nervous message send from top to bottom.
  • Different pathology of movement (for example the erebro motor infirmity), cause and consequences.

Our next tale is under construction and will be called Mimi in the land of place cells.



Mimi in the land of place cells

Mimi, out little microglia, immune cell of the brain, will have new adventures. She is surprised that detailed information come from neurons of a brain region, the hippocampus, when we are searching for something. Neurons are always happy to call them for help, they never failed when it’s about situating thing in the environment. Mimi is really curious to know how they are organized to work so efficiently. In comparison, where Mimi is working at the moment, the parietal cortex, where we manage attention to a direction or another, neurons receive information from everywhere and are obliged to eliminate some of them, choosing most important ones but sometime not choosing very wisely.

It’s time to take some holidays and Mimi know exactly where to go: the hippocampus and theses special cells that are called place cells. It’s them that enable us to oriented in space. Mimi arrived at the moment of a “research time”: apparently, we lose something and we have to find it back. The idea is to look everywhere, where we come from. Mimi helps the microglia there in the mean time discovering the functioning very specific and hierarchic of theses neurons : place cells.

There, she met a neuron that don’t see himself as very useful next to his colleagues, but is he right ? As for mimi, she is going to review her knowledge about the brain, did the brain do mistake everywhere sometimes?

 

Scientific knowledge:

  • inattentional blindness, when we don’t see something because we are not focusing on it
  • the functioning of spatial localisation and cell population involved and well known: place cells and grid cells
  • the hippocampus
  • the discovery of another reality of the brain: do mistakes are necessary?
  • nocturnes activity evocation
