2.  Limbic System  Emotions & higher mental functions  Blends primitive emotions (rage, fear, joy, sadness) with high mental functions (reason, memory)

3.  Anatomy  Hippocampus Seahorse shaped structure Deep in temporal lobe Involved in storage of long-term memory Injured cannot form new memories  Amygdala Allows us to feel certain emotions and to perceive them in other people This includes fear and the many changes that it causes in the body

6.  Types of memory  Short-term memory This ability to hold on to a piece of information temporarily in order to complete a task It causes certain regions of the brain to become very active, in particular the pre-frontal lobe It holds a small amount of information (typically around 7 items or even less) readily-available state for a short period of time (typically from 10 to 15 seconds, or sometimes up to a minute).

7.  Long-term memory  anything you remember that happened more than a few minutes ago  Long-term memories can last for just a few days, or for many years

11.  Long-term memories are stored in bits and pieces throughout sensory association areas in cerebral cortex  Visions stored in visual association area  Sounds stored in auditory association area  Hippocampus involved in storage of short- term memory and storing into Long-term memories

12.  Language and Speech  Language is dependent upon semantic memory  involves Broca’s and Wernicke’s areas. Damage to broca’s area can result in inability to speak Damage to Wernicke’s area inability to comprehend speech https://www.youtube.com/watch?v=otviTWRZJuU
