Luria and Mesulam Models

Question 1

What are the two parts of the brain as stated by the Luria Model?

Answer 1

The Front part of the brain - the motor unity and the Posterior part of the brain - the sensory unity

Question 2

What area of the brain does the Luria Model focus on?

Answer 2

The cortical area - the cortex

Question 3

What unit receives the first input for the brain?

Answer 3

The sensory unit receives information first and then it is transferred to the motor unit.

Question 4

What is the Luria Model in 6 steps?

Answer 4

1. Primary sensory area - occipital cortex, auditory cortex and somatosensory cortex recieves unimodal sensation.
2. Secondary sensory unit elaborates on the sensations - they remain unimodal
3. Tertiary sensory unit integrates the sensations hetromodally.
4. Tertiary motor unit plans what to do with the sensations - prefrontal cortex
5. Secondary motor unit takes these plans and breaks them into sequences
6. Primary motor unit executes the actions - motor cortex

Question 5

What are the 4 functional units in the Luria model?

Answer 5

1. Arousal and attention unit
2. Sensory input and integration unit
3. Executive planning and organisation unit
4. Limbic System

Question 6

How many large-scale networks does Mesulam suggest brains have?

Answer 6
