Limbic SystemEmotions & higher mental functionsBlends primitive emotions (rage, fear, joy,
sadness) with high mental functions (reason, memory)
AnatomyHippocampus
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

Memory & Learning Memory
ability to hold a thought in mind or to recall events from the past
Range from a word we learned yesterday to an early emotional experience that shaped our lives
Learning Takes place when we retain and utilize our past
memories
Types of memoryShort-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).
Long-term memoryanything you remember that happened
more than a few minutes agoLong-term memories can last for just a few
days, or for many years
Semantic memory Idea, concepts and meanings General knowledge about the world
Names of colours, capital of CanadaBasic facts that have been collected over
lifetimes Episodic memory
recollection of specific events, situations and experiences Your first day of school, your first kiss,
attending a friend's birthday party and your brother's graduation
Skill memory Involved in performing skills
Riding bike, playing hockey, using a keyboard Skills that become automatic or learned
Case study:Physicist named SS hippocampus was
selectivley destroyed by a virusHad a high IQ Could remember childhood events, physicis

Long-term memories are stored in bits and pieces throughout sensory association areas in cerebral cortexVisions 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
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
