what is your morality

my cblog for this week is to discuss morality.
Yes punishments are bad and yes you shouldn't break the law and yes there are justifiable situations but my question is what morality are you? and if you are postconventional what situations are ok to break the law and kill, steal, ect.

That is my question. What morality are you? what type of situation would cause your morality to change?

Test taking

This week we had a test on unit two and the beginning of unit three.
There were a few questions that i got wrong because of careless reading errors.
I have had trouble taking tests for as long as i can remember. And here are a few things that a learned about taking multiple choice tests.
-make sure you circled the right bubble. On one of the questions i chose the right answer but i circled the wrong answer and then i didn't go back through the test to make sure i circled all the bubbles correctly.
-Read carefully. One thing you can do is underline important terms in the questions. EX. i got a question wrong because I read 'brain' instead of 'brainstem.' again more careless errors.
-Another thing is that when/ if you underline important terms in the questions define them in your mind correctly. IE genetics: the study of DNA and their effect on evolution, life, heredity, ect

These are some things that i am trying to keep in mind while I take tests. I have not perfected these methods and they may not work for everyone but I can guess that a few of you have this problem too and I hope that my tips may help on your test taking abilities.

My hypothesis on the tongue eyeball

Sensations of the tongue travel to the nucleus of solitary tract (the area of the brain responsible for interpretation of taste bud information) via the glossopharyngeal nerve.

Sensory sensations of the tongue are delivered to the sensory strip (posterior to the frontal lobe) of the brain where it is interpreted and then the information (sensation) is sent to the motor strip of the brain (anterior to the parital lobe). Here a response is conducted and sent to the tongue through the glossopharyngeal nerve.

My hypothesis: What the electrodes placed on the tongue do is deliver a shock (stimulus) to the tongue in varying areas and varying strengths based on the color (tint/ shade) and distance of an object from the camera placed on the camera. What happens in the brain is that as a person learns to associate stimuli with colors, distances, sights, ect… the area in the brain responsible for taste interpretation develops further and its neurological pathways extend. The occipital area of the brain is also utilized. The occipital lobe, that has sat nearly dormant because of the lack of vision, is now rewired in correlation with the taste sensory area of the brain. As these two develop further together their functions (receiving information for sight) intertwine and a person is able to ‘see’ again. Another that happens is the person’s sense of taste and sensations in the tongue are increased because of the heightened function and neural wiring of the taste and vision sensory areas of the brain.

IMPORTANT

one key piece of information was left out of my summary of morphine I posted it as a comment of my morphine blog post. READ IT

Morphine

Morphine is a narcotic pain reliever. It belongs to the opiate family of drugs and contains the principal alkaloid in opium and the prototype opiate analgesic and narcotic. Morphine suppresses the couch reflex and some side effects are constipation and nausea. Morphine attaches to three specific receptors (mu, delta, and kappa)in the brain and act as an antagonist. Morphine reduces the chances of ion channels to open on these receptors. Meaning, very roughly, less channels open; less neurotransmitters received; less pain and other sensations like that produced; a sense of euphoria is instilled. Another thing morphine does is it debilitates the amount of GABA released. GABA is what is used to suppress the releasing of dopamine. So, if GABA is inhibited, more dopamine is released and more pleasure (along with mood swings and dependence on morphine) is elicited.

If morphine is used for a long time it inhibits the activation of cAMP. But cAMP production is picks up by other mechanisms and if morphine is then dropped (no longer used) there becomes an over production of cAMP which leads to hyperactivity and an intense craving of the drug.

The constipation and nausea side effects are caused by morphine acting on the myenteric plexus and the submucous plexus in the digestive tract. Morphine slows, if in high enough doses stops, the plexus’s functions which causes the constipation because the food is not being broken down or moved along the tract.

If this drug is misused, how to counteract the effects of this drug involves; the use of other drugs to fight off the digestive malfunction side effects, and slowly take less and less of the opiate to make the withdrawals less severe and less frequent. Another effect of morphine is mood swings. If enough morphine is taken mood swing can parallel with those of bipolar and even borderline individuals and it may be necessary to take psychotropic drugs to counteract the mood swings.
