​One-shot intrinsic reward valuation in humans
Humans continuously need learn to make good choices in our environment - be it using a new video-conferencing set up, or selecting which location in a house is least likely to be interrupted by toddlers during work calls. However, the goals we seek to attain - such as using zoom successfully - are often vaguely defined and previously unexperienced, and in that sense cannot be known by us as being rewarding. How does the brain enable us to immediately encode such one-shot goals as having value as intrinsic reinforcers? We...

    It's extremely interesting how the dopaminergic neurons *depress* approach signals in response to punishment, and avoidance signals to rewards. I've been thinking this way about brains in general for a while now - wondering if humans/animals are in fact just following hierarchical action chains that steer us clear of learned unpleasant experiences and toward rewarding experiences, in a sort of autonomous cyclic perpetuating loop. It's only when a new unpleasant or rewarding experience is encountered that this otherwise "situated" state of our brains changes. Gold!

      @@neillamas8929 Centers in the limbic system, specifically the basal ganglia, impinge dopamine upon the rest of the structures of the brain to elicit activity and/or reinforce it. This is common knowledge amongst those who've studied the brain to any degree, even those who've Google'd it out of curiosity. The Vental Tagmental Area is responsible for most of the dopamine released into the brain, and the Striatum is where goal-directed behaviors and habits are learned.

    A clarification - my talk is about studying brain processes and treatment of brain disorders such as schizophrenia or addiction with D2 dopamine receptor antisense RNA. HSV (herpes simplex virus) is mentioned as a potential tool (from several viruses) to deliver gene therapy (antisense RNA) in brain because it has propensity to infect neurons. If used for such purposes, it has been modified so that it is not pathogenic. Here is a relevant paper on the potential of HSV for gene therapy. pubmed.ncbi.nlm.nih.gov/12573050/ . However, in our studies we did not use gene delivery with viruses, but with non-viral plasmid vectors, which we reasoned are safer to use.

    I was infected with genital herpes in 2018 and I have been on the quest for a cure since then. October last year when I almost gave up, I stumbled upon a post on the internet where I copied the email of a man named Dr Iniboku who provides herbal solutions to diseases. i contacted him and got to an agreement with him and he sent me herbal remedy through DHL parcel service alongside instruction on how to use it. To my greatest surprise, I got healed after 18days of using the remedy as assured by the doctor. I decided to share this today being one year since I last had an outbreak.

    Hi everyone! Some months ago I had s*x with the fifth guy in my life whom i was about to marry and now I have herpes. I couldn’t believe it because he wasn’t a random guy, he’s the closet guy I’ve had as a boyfriend, but it has been a never ending nightmare since. I’ve always believed in GOD and have asked him for forgiveness which is ironic.<br/>I felt like the world is over for me, myself with the taught of having a husband and family will be quite difficult and i felt like I’m not really in the room when people are talking. I didn’t know what to do and pretty much cry and pray every day to God for help and looking at my family with so much love and feeling that i have disappointed them even though they don’t know. Until God lead me to DR. DOHGO online while doing research, who promised to help me cure my terable virus through herbals remedy. At first i didn't believe him because my fear was in this medication was safe, but to my greatest surprise i was cured completely by DR DOHGO herbals formula, which medical doctor also verified that i was cured. Special thanks to DR. DOHGO.<br/>Don't be discourage because he that did it for me will also do it for you and you can contact him through his email address doctordohgo@gmail . com or text him on WHATSAPP phone number +2347062142293
