<Questions>

  1. According to the speaker, sleeping may become your secret memory weapon for all of the following except for
  1. improving your relationships with other people.
  2. studying for an exam.
  3. learning a new musical instrument.
  4. mastering a new sport.

 

  1. Sleep is critical for memory in at least three different ways. Fill in the blanks.

<#1: We need to sleep (1)                   learning to soak up new information.>

  • Sleeping will get our brain
    (2)                   to learn.

 

  • Sleep will help our brain
    become like a dry sponge.                                          

    → Without sleep,
    the memory circuits within
    the brain effectively
    become (3)                           .




<#2: We need to sleep (4)                   learning to essentially hit the save button.>

  • Sleeping will cement
    new memories into
    the architecture
    of the neural networks.

 

  • We have begun to discover
    exactly how sleep achieves
    this memory-consolidation benefit.

 

[First mechanism: a (5)                           process]

 

Hippocampus = It is like
a (6)               stick of our brain.
We gather lots of files during
the day, and store them in it.

 

Cortex = It is like
the (7)                             (2 words)
of our brain.
We transfer the files
in the hippocampus
into the cortex.




 

[Second mechanism: (8)                   ]

 

<Experiment>

    1. Scientists were looking at
      how rats learned as they would
      run around a (9)                   .                       

      → Scientists were recording
           the activity in the
           (10)                                     (2 words)
           of these rats.

    2. As the rat was running around,
      different brain cells coded
      different parts of the (11)                   .
       
       
    3. When the rat was sleeping,
      it started to reply the same memory,
      but it started to replay it 
      almost (12)                   times faster
      than it was doing when it was awake.

 

<#3: (13)                         and association.>

  • Sleep does not just
    simply strengthen
    individual memories,
    but sleep interconnects new
     (14)                           together.                            

    → As a consequence,
    we can wake up the next day
    with a revised mind-wide web
    of associations.

    → We can come up with
    (15)                          to previously
    impenetrable problems.

  1. Sleep is critical for memory in at least three different ways. Fill in the blanks.

<#1: We need to sleep (1)  before   learning to soak up new information.>

  • Sleeping will get our brain
    (2)  ready   to learn.

 

  • Sleep will help our brain
    become like a dry sponge.                                          

    → Without sleep,
    the memory circuits within
    the brain effectively
    become (3)  waterlogged   .




<#2: We need to sleep (4)  after   learning to essentially hit the save button.>

  • Sleeping will cement
    new memories into
    the architecture
    of the neural networks.

    exactly how sleep achieves
    this memory-consolidation benefit.

 

[First mechanism: a (5)  file-transfer   process]

 

Hippocampus = It is like
a (6)  USB   stick of our brain.
We gather lots of files during
the day, and store them in it.

 

Cortex = It is like
the (7)  hard drive   (2 words)
of our brain.
We transfer the files
in the hippocampus
into the cortex.




[Second mechanism: (8)  replay   ]

 

<Experiment>

  1. Scientists were looking at how rats learned as they would run around a (9)  maze   .
    → Scientists were recording the activity in the (10)  memory centers    (2 words) of these rats.
  2. As the rat was running around, different brain cells coded different parts of the (11)  maze   .
  3. When the rat was sleeping, it started to reply the same memory, but it started to replay it almost (12)  10    times faster than it was doing when it was awake.

 

<#3: (13)  integration   and association.>

  • Sleep does not just
    simply strengthen
    individual memories,
    but sleep interconnects new
     (14)  memories   together.                            

    → As a consequence,
    we can wake up the next day
    with a revised mind-wide web
    of associations.

    → We can come up with
    (15)  solutions  to previously
    impenetrable problems.
