type of biological rhythm:
Circadian: circa (about) dian (day) daily, from the Latin roots words
An example to illustrate major terms related to biological rhythms
Martha McClintock in 1970: menstrual synchrony
Possible reasons: lifestyle, chemical (pheromones – chemical that one organism releases that changes the behavior of another organism)
Results of the sweat study: Yes, odor changes pheromone effect in humans
Other studies on pheromone effects in humans: hanging around males makes women more fertile (pheromones)
oscillators
Rhythms are maintained by internal clocks
entrainment
These clocks can be “reset” by environmental cues
zeitgebers
The environmental cues that reset clocks. German for “time giver.”
What is the major concept about circadian rhythms in humans?
Normal internal day is slightly more than 24 hours long (24+ up to 25 for some people). Thus, it must be reset regularly or our cycle gradually moves forward in time.
The dominant zeitgeber for humans circadian rhythms is light, although there are others (timing of eat, social activity, etc.)
Applications of research on human circadian rhythms
Helping students realize that sleepiness and depression can be caused by irregular schedules that prevent their rhythms from being resent. Research has suggested strategies for resetting these rhythms.
Help industries create shift work schedules that are more compatible with these rhythms.
Help look for cures for mental disorders that might be partly circadian rhythms disorders, such as seasonal affective (emotional) disorder (SAD).
Medicine and chronobiology (study of time to take medication)
psychoactive drugs
drugs that influence behavior, mood, or consciousness.
What is Drug Abuse?
Pattern of pathological use (such as intoxicated all day or inability to decrease use)
Impairment in social or occupational functioning
At least one months’ duration
What causes Drug Abuse?
Family history (genetics)
Availability (use and age of use)
Context in which you use it
psychological dependence
addicted to routine of the drug or role of drug in in life
withdrawal
physical reaction when a person stops using a drug
addiction
when physiology of the body changes in specific ways. Most drugs that addicts causes tolerance.
tolerance
less response to a specific does with repeated use. Cross-tolerance also occurs (tolerance to one substance/drug and automatically tolerant to another drug never taken).
stimulant drugs:
caffiene, cocane, and amphetamines
caffiene
Activates brain, alerts. At least three mechanisms:
Adenosine is created in the brain and binds onto adenosine receptors. Binding causes drowsiness by slowing down nerve cell activity. Adenosine puts the brakes on your brain.
Caffeine looks like adenosine to your brain; it binds on but without slowing activity.
Also increases dopamine in the brain by blocking reuptake.
Tolerance develops and there is withdrawal after 18 hours, often in users of 5 or more cups per day.
caffienism
symptoms of a panic attack
The American Psychiatric Association recognizes four caffeine-induced disorders:
Caffeine intoxication
C-induced sleep disorder
C-induced anxiety disorder
C-related disorder not otherwise specified
