Week3 – Memory

This is the video about memory:

And these are some informations about memory:

The many kinds of studies of human and animal memory have led scientists to conclude that no single brain center stores memory. It most likely is stored in distributed collections of cortical processing systems that are also involved in the perception, processing, and analysis of the material being learned. In short, each part of the brain most likely contributes differently to permanent memory storage.

Repeat to remember: Short-term memory
The brain has many types of memory systems. One type follows four stages of processing: encoding, storing, retrieving, and forgetting.
Information coming into your brain is immediately split into fragments that are sent to different regions of the cortex for storage.
Most of the events that predict whether something learned also will be remembered occur in the first few seconds of learning. The more elaborately we encode a memory during its initial moments, the stronger it will be. You can improve your chances of remembering something if you reproduce the environment in which you first put it into your brain.
Remember to repeat: Long-term memory
Most memories disappear within minutes, but those that survive the fragile period strengthen with time. Long-term memories are formed in a two-way conversation between the hippocampus and the cortex, until the hippocampus breaks the connection and the memory is fixed in the cortex— which can take years. Our brains give us only an approximate view of reality, because they mix new knowledge with past memories and store them together as one. The way to make long-term memory more reliable is to incorporate new information gradually and repeat it in timed intervals.
Sleep is vital for the consolidation and integration of memories during the formation process. Sleep is biological creativity. The difference in how the brain handles learned information before and after sleep is the difference between knowledge and wisdom.  Learning involves 3 steps for memory formation – 1. encoding  2. consolidation and integration 3.  recall.  Sleep is vital for the 2nd stage.  The last 2 hours of our sleep is most critical for consolidation and yet our sleep is often cut short.  Sleep physically changes the geography of memories.  After sleep the location in the brain of our learning has actually moved.

Extra Video – How Memory Works – with Dr. Antonio Damasio

Dr. Antonio Damasio is a renowned neuroscientist. His research focuses on the neurobiology of mind and behavior, with an emphasis on emotion, decision-making, memory, communication, and creativity. His research has helped describe the neurological origins of emotions and has shown how emotions affect cognition and decision-making.

In Search of Memory (Trailer)

„IN SEARCH OF MEMORY“ (film) examines how the brain stores memories, the difference between short-term and long-term memory, Alzheimer’s and age-related memory loss, and structural modifications to the brain that enhance memory. In revisiting the people, places and objects of Kandel’s lifetime experiences, IN SEARCH OF MEMORY reveals how everything we undergo changes the brain, even our genetic make-up, and can determine the focus of a life’s work.

My reflections upon the memory

  • I can conclude that, for the best results, it is recomanded to match the information with earlier knowledge
  • It is possible to increase brain development (neural and synaptic) with reach environment
  • The lymbic sistem with amygdala are switching station for the brain input wich means that if one is under the stress and his lymbic sistem is engaged, the learning process is stopped
  • Memory is constructed by pattering (prior knowledge with similar pattern links with new information)
  • memory takes place when there has been activation of the brain’s related prior knowledge before new information is taught.
  • The more times one repeats an action, the more dendrites grow and interconnect, resulting in greater memory storage and recall efficiency.
  • Multisensory instruction, practice, and review promote memory storage in multiple regions of the cortex, based on the type of sensory input by which they were learned and practiced.
  • Memory is matter of the brain as a whole rather than one specific point!
  • And, finally, the most important conclusion is that teachers have a role of the main person who make a great impact on child’s brain development. That is a huge responsibility
  • Learning process finishes with sleeping! If the teacher has the main role in acquiring informations, what consolidates them is sleep! I can only notice that our students don’t sleep enough or they don’t have a good sleeping-rythm which prevents learning to be complete!
