Consciousness depends on feeling and feeling depends on how well or bad you’re doing in life
What is the diffference between a mind and brain?
A mind cannot be seen (maybe only through actions) while a brain can
How do FMRI and PET scans contribute to better understanding brain function?
FMRI measures hemodynamics in the brain during tasks, while PET scans measure metabolic activity for single neurotransmitter systems
Why is neuropsychology not the best discipline to use when attempting to understand the mind?
Neuropsychology studies the tools of the mind and how they operate (the brain), rather than the mind itself
What is dreaming?
Periods of consciousness during unconsciousness
What provides data during a psychoanalytic session?
The free association of the patient
What part of the brain does REM sleep generate from?
The brainstem
What circuit do modern antipsychotic medications work on, and how do they work?
The mesocortical-mesolimbic dopamine circuit. They block dopamine at the terminals of this brain circuit
What is the major brain circuit responsible for dreaming? Is it affected by REM sleep?
The mesocortical-mesolimbic circuit.
No
What significance does the mesocortical-mesolimbic circuit have for a human?
It is the circuit that provides the most energetic exploratory and search behavior in humans AND it drives dreaming
Where are the neurons located that drive the mesocortical-mesolimbic brain circuit? What does this imply about dreaming?
In the brainstem, from where they project axons cortically. This implies that dreaming initiates subcortically
