Acetylcholine
- Usually excitatory (always excitatory in the musculoskeletal system)
- FN: Motor movement, cognitive function
- location: CNS; PNS
- Alzheimer’s disease
Norepinephrine
- Excitatory
- FN: “Fight or Flight” response
- Location: CNS; PNS
- Depressed mood
Dopamine
- Excitatory or inhibitory
- FN: Happiness, motor movement, alertness, learning, emotion
- Location: CNS; PNS
- Parkinson’s disease
Serotonin
- Inhibitory
- FN: Sleep, appetite, mood regulation, arousal
- Location: CNS
- Mood disorders (e.g. depressive disorders)
Glutamate
- Always excitatory (key excitatory neurotransmitter of CNS)
- FN: Stimulates the brain
- Location: CNS
- Lack of focus or motivation
GABA
-Always inhibitory (key inhibitory neurotransmitter of CNS)
-FN: Calms the brain
-Location: CNS
Anxiety, seizures
Endorphins
- Inhibitory; provides pain releif
- FN: Pain relief
- Location: CNS
- Pain
How neurotransmitters function in relation to membrane potential
Neurotransmitters exit via exocytosis from the presynaptic terminal, travel across the synaptic cleft, and then bind to receptors on the target cell where they induce changes in the neuronal membrane’s permeability to ions
- Excitatory = more likely to fire an AP
- Inhibitory = less likely to fire an AP
Cerebrum
Forebrain
Problem-solving and learning, emotions, coordination of movement
Thalamus
Forebrain
Sensory relay station; processes and conveys all sensory information except for odor (smell)
Hypothalamus
Forebrain
Controls appetite, moderates body temperature, secretes hormones
Superior colliculi
Midbrain
Receive and process visual information
Inferior colliculi
Midbrain
Receive and process auditory information
Cerebellum
Hindbrain
Coordinates movement, posture, and balance
Pons
Hindbrain
Bridge between cerebellum and forebrain
Medulla oblongata
Hindbrain
Regulate cardiovascular system (breathing, heart rate, blood pressure, etc.)
cerebral cortex
- Outermost part of the cerebrum
- Responsible for many of our higher cognitive functions
- Rich with the cell bodies, or soma, of neurons. These neurons have long axons that extend through the brain and into the spinal cord.
- 4 major lobes
Four lobes of the cerebral cortex
Frontal lobe: governs executive function, initiates voluntary motor movement, and is responsible for producing speech. Broca’s area is on left side of frontal lobe.
Parietal lobe: governs spatial processing, proprioception, and somatosensation.
Occipital lobe: governs visual processing.
Temporal lobe- governs learning, memory, speech perception, and auditory perception. Wernicke’s area is located here.
To explain the demographic dynamics in the passage, a conflict theorist is most likely to consider the relationship among which factors?
Generational status, political power, and resource allocation
- The sociological paradigm of conflict theory broadly calls attention to competition among social groups, including generational conflict. Given the demographic dynamics raised in the passage, it is likely that competition over resources will emerge between the old and the young (for example, public support of health care versus education, each of which tends to benefit one age group more than the other). A conflict theorist would be interested in explaining how political power varies by generational status and thus affects the allocation of social resources.
The aging of the U.S. population is most likely to increase:
the dependency ratio
The dependency ratio is a ratio of the number of economically dependent members of the population to the number of economically productive members. The economically dependent are those considered too young or too old to work, whereas the economically productive are the working-age population (approximately between the ages of 18 and 65).
The linguistic relativity hypothesis
(Weak) suggests that human cognition is affected by language
- more relevant = more easy to comprehend
ex) Humans are better at distinguishing colors for which their language has a name.
(Strong) language determines thought, and that linguistic categories limit and determine cognitive categories, whereas the weak version says that linguistic categories and usage only influence thought and certain kinds of non-linguistic behavior
Sapir-Whorf hypothesis
the grammatical structure of a person’s language influences the way he or she perceives the world
Source monitoring error
A type of memory error where the source of a memory is incorrectly attributed. Often due to limited encoding of source information. Memory construction can follow leading to a false memory.
- the older the memory, the more likely the source will be mixed up
Dissociative disorder
Disruptions in awareness, memory, and identity that are extreme or frequent enough that they cause distress or impair the person’s functioning.
- Dissociative disorders can be triggered by severe stress or psychological conflicts and they usually begin and end suddenly
