memory Flashcards
(26 cards)
memory
capacity to retain information about itself and the envirnonment
dois tipos de memória
phyletic (innate) e ontogenic (acquired)
different states da memória ao longo do tempo
encoding (active), storage (inactive), retrieval (active)
tipo de long-term memory/declarative/explicit
episodic memory (events), semantic memory (facts)
tipo de short-term memory/nondeclarative/implicit
procedural memory(skills), perceptual representation system(perceptual priming), classical (conditioned responses between two stimulus)
Declarative memory: partes responsáveis
Medial temporal lobe (MTL) specially hippocampus
o que preve a performance da memoria declarativa?
hippocampi
MTL importante para?
consolidation. a partir do momento em que cortical networks grow stronger, hippocampal connections tornam-se desnecessárias
memory consolidation
process where memory form stronger connections and becomes stable and long lasting
Prefrontal cortex importante para?
encoding and retrieval. Encoding by organizing the knowledge and retrieval by guiding memory search and evaluating information
Parietal cortex importante para?
it supports prefrontal function in its executive role and for spatial context
Sensory regions
important for episodic memory and activated during retrieval
semantic memory localiza-se mais onde?
left hemisphere (temporal, frontal and parietal)
episodic memory depende do que?
entire neocortex cause different content is localized in different areas of the brain
tipos de skill learning
perceptual, motor or cognitive
new skills rely on higher regions como?
dorso lateral prefront cortex (DLPFC) and cerebellum
skills que ficam automáticas e decoradas reply on lower regions como?
basal ganglia and cerebellum
classical coditioning
neutral tone is associated with air puffs in the cerebellum (inner reflex modified by repeatedly associating trigger stimulus with unelated stimulus)
fear conditioning
neutral tone is associated with fearful eletrical shocks and depends on the amygdala
o que é priming?
neural changes in different partes of the neocortex depending on priming context
working memory
temporary retention of information for prospective use/temporary activated long-term memory
que neurónios estão involvidos na working memory?
prefrontal neurons
color is maintained in working memory através de?
sustained activity of color-specific neurons in the temporal cortex
information is maintained in working memory através de?
recurrent activity between temporal(posterior cortical) and prefrontal cortex
