Why do psychopaths go after what they want regardless of the negative consequences they may experience? According to the journal Nature Neuroscience, the answer may be chemical—an overactive dopamine reward system.

Read Driven toward reward without regard for consequence on Time.com.

Read the scientific study, Mesolimbic dopamine reward system hypersensitivity in individuals with psychopathic traits, in Nature Neuroscience.

    hmmm, oxy and EB have disappeared…lock your doors!

    how are things going there today hens?

    been a long day here – 1:30 now, will need to pack it in soon.
    A job i had been talking to someone about vaporized – a good thing as it would have been quite horrid me thinks, but things are going to get real ugly here soon.

    am on the trail of some resources for PTSD. this is good. and i have fullfilled some volunteer obligations that i thought i might not be able to. i am not getting a lot done everyday, but some, and sometimes more than i expect to, given how uneven i am right now.

    ‘He said: “To keep living as I did up until today would be to indirectly diminish the glow that my kids where born with. Enough is enough. This has to change.”‘

    well, i like the quote – but his assertion that’ “I am proud to say that I am a fortunate homosexual man.’ is a bit odd.

    as opposed to an unfortunate homosexual man, or to a fortunate heterosexual man? i am going to believe that something got lost in the translation

    i hope you get some support for ptsd one – i really think it takes a bout 2 and half years to recover from a sociopath, i have read that in several diiferent places – i am so far on the other side of it 2 years but still think i have more to process so maybe the next 6 months will bring that closure – funny thing happened tonite – I heard my first whiporwill (bird) they have always brought me such calm and connection with the universe and nature a sign that life goes on i felt joy when i heard it – when my boys were little we would listen for them at nite, one of my boys called them whirlwhips – anyway i told then when i am gone every time they here the first whiporwhil in the spring it is me saying hello…

    nice. a gift to your sons.

    i have a little woods just across the road from me. it’s a magical place, one of my favourite woods. someone carved a chair out of a stump (probably for their kids ;)). I went out and sat in it for a long time today. The birds are so happy that it is spring…i closed my eyes and swooned to the sound of them.

    okay the 2.5 year timeline is good t know about. i am okay with that – i just need to be able to function enough to work. beyond that, healing can have most of my time and energy.
