    Your brain contains billions of nerve cells arranged in patterns that coordinate thought, emotion, behavior, movement and sensation. A complicated highway system of nerves connects your brain to the rest of your body, so communication can occur in split seconds. Think about how fast you pull your hand back from a hot stove. While all the parts of your brain work together, each part is responsible for a specific function - controlling everything from your heart rate to your mood.

  • a very specific kind of emotion-based judgment is altered when the region is offline
  • emotional system
  • utilitarian cost-benefit analyses
  • ventromedial area
  • ventromedial area
  • blind to subtle social cues, making them socially awkward
  • strongly rejected doing harm to others in situations that were not a matter of trading one certain death for another.
  • direct action to kill or harm someone
  • Those with ventromedial injuries were about twice as likely as the other participants to say they would push someone in front of the train
  • navigate social interactions
  • brain stem
  • amygdala
  • emotional memories,
  • social emotions that we can feel, like embarrassment, guilt, compassion that are critical to guiding our social behavior,
  • ension between cost-benefit calculations and instinctive emotion
  • ancient principle: respect for the life of another human being

      It would be interesting to see whether other primates use the ventromedial cortex for similar responses to dilemmas involving conspecifics.
  • increased willingness to kill or harm another person if doing so would save others' lives

      I wonder what would happen if you adjust the identity of the sacrificable person. What happens if person is a stranger versus a family member? They do run the "smother your baby" dilemma. Does it make a difference if it is a stranger? What about alternative to the other five victims? What information is the VMPFC working with?

    A novel bioinformatics approach can predict vaccine effectiveness for the influenza season, and indicates that the current vaccines are likely to be effective against H3N2 flu viruses in the U.S. 2017/2018 flu season, according to research published online Nov. 29 in F1000 Research. Slobodan Paessler, D.V.M., Ph.D., from the University of Texas Medical Branch, and Veljko Veljkovic, Ph.D., from Biomed Protection, both in Galveston, Texas, used a bioinformatics platform to predict vaccine effectiveness for the 2017/2018 influenza season in the United States. The hemagglutinin HA1 region of 251 and 113 human H3N2 viruses collected in Australia and the United States from July to September 2017 were analyzed. The informational spectrum method-based phylogenetic analysis of H3N2 viruses was performed to serve as a base for predicting vaccine effectiveness. The researchers found that analyses of Australian viruses generated two clusters; the vaccine virus was placed in the smaller group. As a result, the vaccine was predicted not to be efficient against most Australian H3N2 viruses in the 2017 flu season; low vaccine effectiveness was reported in Australia in the 2017 flu season in accordance with this prediction. The U.S. H3N2 viruses were also grouped into two clusters, but the vaccine virus was placed in the largest cluster encompassing 71 percent of analyzed viruses. Consequently, the vaccine effectiveness is expected not to be suboptimal in the United States.
