Lecture 24:
●Functionality- the systems that we described were based on our experimental manipulation of
neurons. Te issue now is what naturally activates/inhibits neuronal activity?
○NT (from other stimulated neurons and pacemakers)
○Sensory events
■External stimuli (ion channels)
■Internal stimuli (ion channels)
●Level of Analysis: Drug Effects
○Brain
○Brain units
○Neuron
○Synaptic ecology
■Precursor modulation
■Neurotransmitter synthesis
■Neurotransmitter storage
■Neurotransmitter release
■
○Agonist- mimics NT effects
○Antagonist- blocks NT effects
○Receptor agonists and Antagonists:
■Heroin
■Marijuana (THC)
■LSD
■Mescaline
■Nicotine
■Caffeine (antagonist)
■Naloxone (antagonist)
○Drug blocks NT Reuptake
○Cocaine- inhibition of dopamine reuptake
●Consciousness
○Substance dualism- mind (consciousness) and body two separate things
○Property dualism- mind(consciousness) emerges from brain activity
○Both assume that the mind (consciousness) and brain can interact, although the basis for
the interaction is not known
○Both assume that the mind (consciousness) is important!!
