Closing points - Intro to Psychology

  • 0:00 - 0:04
    Throughout evolution, humans brains have grown larger and more complex. And
  • 0:04 - 0:09
    that allows us to do all the amazing things that we can do. Everything about
  • 0:09 - 0:13
    who we are, what we like, how we think, what we dream. And even how we feel is
  • 0:13 - 0:18
    a function of our brain and its electrical and chemical activities. The nervous
  • 0:18 - 0:22
    system is divided into the central nervous system that is comprised of the
  • 0:22 - 0:27
    brain and the spinal cord. And the peripheral nervous system that consists of
  • 0:27 - 0:31
    the somatic nervous system, which controls voluntary behavior. And the
  • 0:31 - 0:36
    autonomic nervous system that controls involuntary behavior. The autonomic
  • 0:36 - 0:39
    nervous system is further broken down into the sympathetic nervous system,
  • 0:39 - 0:44
    which is our fight or flight responses. And the parasympathetic nervous system,
  • 0:44 - 0:49
    which produces the opposite effects and relaxes the sympathetic nervous system.
  • 0:49 - 0:54
    Neurons are specialized cells that communicate with each other via electrical
  • 0:54 - 0:59
    and chemical signals. Sensory neurons receives sensory information and send it
  • 0:59 - 1:03
    to the brain for processing. The brain then sends information to our motor
  • 1:03 - 1:06
    neurons that allow us respond appropriately, and the interneurons form
  • 1:06 - 1:11
    connections between neurons. After an action potential has occurred, neurons
  • 1:11 - 1:15
    can release neurotransmitters, which are naturally occurring chemicals that
  • 1:15 - 1:21
    produce a cascade of effects. Some important neurotransmitters in the study of
  • 1:21 - 1:27
    psychology are, Dopamine, Serotonin, Acetycholine, Gabba, and Glutamate. As
  • 1:27 - 1:33
    well as our natural occurring Endorphins. The brain is divided into twp
  • 1:33 - 1:39
    hemispheres, left and right. And those communicate via the corpus collosum. The
  • 1:39 - 1:43
    upper-most portion of the brain is the cerebrum. And the frontal lobe is
  • 1:43 - 1:48
    important for attention, working memory, impulse control, and abstract thinking
  • 1:48 - 1:53
    and creativity. It is the youngest part of the brain and the part that makes us
  • 1:53 - 1:58
    most human. We are better able to determine what the different parts of the
  • 1:58 - 2:03
    brain are responsible for due to advances in brain imaging techniques such as
  • 2:03 - 2:09
    EEG, fMRI, and PET scans. These allow for researchers to see what parts of the
  • 2:09 - 2:12
    brain are activated when we engage in various activities, such as talking,
  • 2:12 - 2:15
    reading or even dreaming.
