How does memory work?

Standard

In class we have been talking about memory and how it works. I have read a text by ScienceDaily about memory and here is what I have learnt.

New Vocabulary

neurotransmitter- a chemical substance that is released by a nerve fibre which allows signals to travel across.

long-term potentiation- long lasting strength of synapses between nerve cells.

Cognitive- process of gaining knowledge

deteriorate- to wear away

impairment- being weakened

Summary

Memory is created when the neurons communicate through synaptic connection with each other when neurotransmitter are there. However, they only connect when they get the same stimulus from the same neurotransmitter. The strength can vary which changes the how strong the memory is formed. A memory is created if the long term potentiation(LTP) is sustained. This happens when each nerve cells talk to each other at an elevated rate. The brain starts to lose it’s memory when the neurons start to decrease and don’t connect as much as they used to before. This is just like our muscles in the body. When we don’t use the muscles for a very long time they start to gradually lose their strength and weaken their strength.

Nigata expedition reflection

Standard

For this years expedition I went to Nigata. In this trip we went on a 3 days hike. img_0813-x3

The two main things we were focusing on during this trip was resilience, self reliance, leader ship and relationship. While hiking I was trying to keep these words in mind. My first goal for the hike was to not give up and keep motivated to finish the 3 day hike. My second goal was to be able to help some people not just when hiking but also when we got to the camp site. I think that I was able to achieve my first goal. It is because during the hike I didn’t think about wanting to go back and I was trying to be motivated by telling myself that this is a new experience so enjoy everything around you. By telling myself this I was able to motivate myself to go faster because I wanted to see what was coming up next. I think that I could have achieved this goal a bit more better. It is because during the hike I was not able to help out as much I was expecting. However at the campsite I think that I was able to help quite a bit. After I was done setting up the tent I was able to help other group put up their tent and I was also able to help people clean up their plates after dinner. niigata-expedition-2016-6384-sniigata-expedition-2016-6216-xlniigata-expedition-2016-6352-s

After the hike when we were doing the boardering I was able to be a risk taker and go up the wall and achieve it until the top of the wall. I was proud of what I was able to do. When we were doing the second activity where we had to do a lot of group work I think that I was good at cooperating and thinking about a solution together as a group.niigata-expedition-2016-2-1060850-l

Also during this expedition I was able to learn about myself. I was able to learn that I like to talk to people around me when I am tired or annoyed so I let out my stress. I also learned that I was able to learn that I was able to live without my phone next to me 24 hours. At first I thought I was going to have a hard time living without my phone because I always look at my phone everyday but I was fine without it and had a lot of fun with the people around me making new friends from other grade.

By going to this expedition I think that I was able to learn a lot of new concepts about the things around me. Also I was able to learn new things about myself which helped me understand who I am better and how I should think about myself.
