Lecture 2 Review Questions Flashcards
What are examples of key types of information that go to multiple brain sites during organization?
Location, shape, images, contrast, color, orientation, sound, numerosity, patterns, motion
How are the multiple brain sites examined?
- Deep electrophiology (for epileptics) - sucortical
2. funtional magnetic Resonance Imaging for others - not subcortical
What is the functional significance of rehearsal in assigning meaning?
The brain is comparing features of novel stimuli with the stimuli stored in LTM (this process happens via the prefrontal cortex)
- Ventrolateral PFC
Cues speciic, strategic search of MTL for stored representations & maintenance of the retrieved information
- Medial Temporal Lobes
Compares retrieval cues and stored representations using pattern completion
- Dorolateral PFC
Monitors and verifies retrieved information
- Anterior PFC
In charge of higher level mnemonic control operations
A. Baddeley and Hitch’s model is a ________ model.
B. Donald Hebb’s Cell Assembly is a ________ model.
A. Cognitive
B. Neural
Stage 1 of Hebb’s Cell Assembly: Presumed ________ between neurons.
Presumed INTERCONNECTIONS between neurons
Stage 2 of Hebb’s Cell Assembly: Cell assembly represents _______ of neurons that are _________ by a learning event.
Cell assembly represents CONSTELLATION of neurons that are ACTIVATED by a learning event.
Stage 3 of Hebb’s Cell Assembly: Interconnected neurons in the cell ________ even after stimulus is _______.
Interconnected neurons in the cell REVERBERATE even after the stimulus is REMOVED.
Stage 4 of Hebb’s Cell Assembly: Hebbian modification - ________ reciprocal connections between neurons that are ______ at the same time.
Hebbian modification - STRENGTHENS reciprocal connections between neurons that are ACTIVE at the same time.
Stage 5 of Hebb’s Cell Assembly: Connection strengthened by _______ _______ contain the ________ for the new event.
Connection strengthened by HEBBIAN MODIFICATION contain the ENGRAM for the new event.
Stage 6 of Hebb’s Cell Assembly: When _____ is complete, ______ _______ of the Cell Assembly leads to activation of the entire representation of an event.
When LEARNING is complete, PARITAL ACTIVATION of the Cell Assembly leads to activation of the entire representation of an event.
