Terms in this set (14)
memory of facts and experiences that one can consciously know and "declare" (Also called declarative memory).
a neural center located in the limbic system; helps process explicit memories for storage
retention independence of conscious recollection. (also called nondeclarative memory).
a clear memory of an evolutionary significant moment or event
an increase in a cell's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory.
long - term potentiation (LTP)
which parts of the brain are elemental for implicit memory processing, and which parts play a key role in explicit memory processing?
the frontal lobes and hippocampus are important for explicit memory formation, and the cerebellum and basal ganglia are the key to implicit memory
your friend has experienced brain damage in an accident. He can remember how to tie his shoes but has a hard time remembering anything told to him during a conversation. What's going on there?
our explicit (declarable) memories differ from our implicit memoires of skills and procedures. Our implicit memories are processed by more acient brain areas. Which apparently escaped damage during the accident.
which brain area responds to stress hormones by helping to create stronger memories?
this neural basis for learning and memory, found at the synapses in memory-circuit connections, results from brief, rapid stimulation. It is called
long term potentiation
what is the capacity and location of our long term memories?
our long term memory capacity is essentially unlimited. Memories are not stored intact in the brain in single spots. Many parts of the brain interact as we form and retrieve memories. Explicit (declarative) memories - our conscious memories of facts and experiences - from through effortful processing, which requires conscious effort and attention. Implicit (nondeclarative) memories - of skills and classically conditioned associations - happens without our awareness, through automatic processing.
What is the role of the frontal lobes and hippocampus in memory storage?
the frontal lobes and hippocampus are parts of the brain network dedicated to explicit memory formation. Many brain regions send information to the frontal lobes for processing. The hippocampus, with the help of surrounding areas of cortex, registers and temporarily holds elements of explicit memories before moving them to other brain regions for long term storage.
what role do the cerebellum and basal ganglia play in our memory processing?
the cerebellum and basal ganglia are parts of the brain network dedicated to implicit memory formation. The cerebellum is important for storing classically conditioned memories. The basal ganglia are involved in motor movement and help from procedural memories for skills. Many reactions and skills learned during our first three years continue into our adult lives, but we cannot consciously remember learning these associations and skills, a phenomenon psychologists call "infantile amnesia"
how do emotions affect our memory processing?
emotional arousal causes an outpouring of stress hormones, which lead to activity in the brain's memory-forming areas. Significantly stressful events can trigger very clear flashbulb memories.
how do changes at the synapse level affect our memory processing?
long term potentiation (LTP) appears to be the neural basis of learning. In LTP, neurons become more efficient at releasing and sensing the presence of neurotransmitters, and more connections develop between neurons.
