Cognitive Neuroscience Lecture 24: Intro to Multiple Memory Systems in the Brain

What is the premotor cortex anterior to?

primary motor cortex

what does the premotor cortex correspond to?

Broadmann Area 6

What is the lateral portion of the premotor cortex?

lateral premotor cortex

What is the medial portion of the premotor cortex called

supplementary motor area (SMA)

what are the frontal eye fields anterior to?

premotor cortex/precentral sulcus

where are the frontal eye fields located?

intersection of precentral sulcus and superior frontal sulcus

what do the frontal eye fields correspond to?

Broadmann Area 8

What do the posterior portions of the frontal cortex link to (such as the primary motor cortex)

concrete, domain specific behaviors (e.g. executing a movement)

what happens when regions become more anterior in the (pre)frontal cortex?

functions become more abstract/internal

what is the Basal Ganglia involved in?

actions/movement and reward and skill learning

degeration of the Basal Ganglia is in

Huntington's disease (hyper-kinetic symptoms)

implication of the Basal Ganglia is in

Parkinson's disease (hypo-kinetic symptoms)

First processing Stage

encoding

Second processing stage

consolidation/storage

Third processing stage

retrieval

Short term memory

limited capacity; conscious awareness

Long-term memory

no requirement for conscious awareness

Sensory Register/Immediate Memory

high capacity, milliseconds/seconds, lack of conscious awareness

Sensory/Immediate memory requires what to become Short-term memory?

Attention

Short term memory requires what to become Long-term memory?
