Memory & Speech Flashcards
stages of memory
- reception of sensory information
- formation of memory trace
- consolidation of memory trace
- recall of memory trace (or retrieval)
occurs in the sensory cortex
reception and interpretation of sensory information
chemical change in tissue that represents formation of a memory
formation of memory trace
formation of memory trace happens in which tissues
they are located in several regions and other cortical areas, prefrontal, limbic system, cerebellum and the temporal lobe
memory can be erased in both of these stages
reception and formation of memory trace
The process by which the information is stored and become resistant to erasing
consolidation
how long does consolidation take and involving what kind of synthesis
process needs at least 5-10 minutes and it involves protein synthesis in neurons
occurs in the hippocampus and its connections
consolidation
dependent on “repetition”
consolidation
related to: gene expression, protein synthesis and hypertrophy of synaptic plates
consolidation
the process by which the stored information are called back by one of the following mechanisms
recall
classification of types of memory is divided into
duration of memory retention and type of information
classification of according to duration is divided into
- immediate / sensory
- primary ( short term, recent or working )
- secondary ( long term or remote ) memory
its duration is less than one second either fades away or changes into primary or secondary memory
immediate or sensory memory
lasts for few minutes, develops from the sensory memory maximum “nine items” can be stored reading the phone number and dial”
primary ( short term, recent or working )
related to hippocampus and parahippocampal regions reverberating circuits
primary ( short term, recent or working )
capacity of the brain for this time of memory is small, but its recall is rapid (working memory)
primary ( short term, recent or working )
It lasts for long times (up to several years) can not be erased
secondary ( long term or remote ) memory
does the hippocampus store information
no it is essential for process of consolidation
classification according to type of memory
- declarative (explicit)
- nondeclarative (implicit) = reflex memory
memory of conscious awareness stored generally in the hippocampus and the medial temporal lobe
declarative explicit recognition memory
not associated with awareness
- nondeclarative (implicit) = reflex memory
does not involve processing in the hippocampus involves the cerebellum and the basal ganglia are
- nondeclarative (implicit) = reflex memory
includes skills, habits, and conditioned reflexes
- nondeclarative (implicit) = reflex memory
