When one is either learning or working with a new concept that is - complex, untangle, counter-intuitive, tedious, multi-dimensional, boring and difficult, it appears mood is altered to a lower state, very similar to that of a depressive state, however is temporary, until another concepts comes along (still new) that is simple, clear and straight ...

I'm guessing you don't want to generally increase the level of those chemicals in the brain, just in the reward-motivation area. In order to do so, you need to be rewarded and motivated, obviously. The learning need to be exciting, with feedback and reinforcement. Socializing it will help, too. There is a relatively new topic, called gameificatin, that try ...

A study Evidence that methylphenidate enhances the saliency of a mathematical task by increasing dopamine in the human brain suggests that using of Methylphenidate that is prescribed for attention deficit hyperactivity disorder (ADHD) increases the performance in mathematical tasks in healthy subjects. Methylphenidate primarily acts as a dopamine-...

Why might sleeping on the floor alleviate PTSD symptoms? Question: Does sleeping on the floor have similar neurotransmitter effects, as sleeping under a weighted blanket might? Psychiatrically, would it be expected that a person having PTSD would find similar results sleeping under a weighted blanket as they do when they sleep on the floor? There ...

I've mostly figured it out now, and I've a better idea of the words and phrases I need to search to get the information I was asking for. The short answer comes from wikipedia: "The neurons' somata produce the enzymes that synthesize dopamine, and they are then transmitted via the projecting axons to their synaptic destinations, where most of the dopamine ...

Not all medications administer dopamine in the same way. For treating Parkinson's specifically, dopamine-boosting medications such as L-DOPA (which are notable for their ability to cross the blood-brain barrier, which dopamine itself cannot do) are often administered with a DOPA decarboxylase inhibitor (DDCI) or with a benserazide to prevent peripheral ...

Parkinson's Disease, as you note, is believed to occur due to damage or degeneration to the basal ganglia, especially the substantia nigra. Cells in the basal ganglia and substantia nigra produce dopamine, and in fact, the majority of the brain's dopaminergic cells have their bodies here, but that isn't the whole story. From Kandel's Principles of Neural ...

Hamid et al. Mesolimbic dopamine signals the value of work. Nature Neuroscience 2016. http://www.nature.com/neuro/journal/v19/n1/full/nn.4173.html Here is a paper that argues that dopamine signals discounted value of future returns. This is precisely what you are asking. the authors argue, that if rewards are further away in time or space, they are ...

Alas there's not much in the way of interventions that can curb impulsivity on the spot. Quoting from a somewhat dated but widely cited review, Moeller et al., 2001: Of the operant therapies used in treating individuals with impulsive-related disorders, contingency management procedures have received the most clinical and research attention. ...

Dopaminergic neurons synthesize dopamine and release it at their synapses with target neurons (see David Sulzer's review article. The activity of a dopaminergic neuron (its instantaneous firing rate) is one of the main determinants of how much dopamine is released per unit time at its many synaptic terminals. The amount of dopamine synthesized is also ...

To answer your question directly, there are so much different factors involved in addiction to games and movies, that I don't believe any study could cover the whole thing. We can, though, try to identify the factors that are different and study them individually. The fundamental difference between movies/series and games, the one thing that separates more ...

Although my formal training involved an element of neuroscience, it was not heavy on neuroscience so I am not aware of any specific neuroscience textbooks. However, another article you may be interested in is: Mathai, A., & Smith, Y. (2011). The Corticostriatal and Corticosubthalamic Pathways: Two Entries, One Target. So What? Frontiers in Systems ...

There is some truth to dopamine correlating with heightened motivation (but dopamine can also be too much of a good thing, such in the case of behavioral addictions, like pathological gambling, especially the presumed iatrogenic kind) However, tiredness or more prceisely sleep depravation affects dopamine receptors so it will impair many brain functions ...

Is there a split between desire and love? Of course, love and lust/desire are two completely different things. A simple definition I have of the word love: An involuntary response to virtue. This obviously means I can't "love" someone without knowing whether or not they are honest, benevolent, or have integrity. It also means that I can't love someone if ...

This is more of a subjective opinion, (though there are some real world examples) but I feel that the concept of "gamification" (adding game-like qualities to non-gaming tasks) is quite relevant to this topic. Sites like khan academy or codecademy use this pretty effectively, and make the process of learning math or code more enjoyable because you are making ...

The ability of dopamine to work on different time scales is discussed by Schultz. More generally, the basic idea of prediction error reinforcement based learning and DA is that the prediction error signal "propagates back in time". There is some doubt for how temporally precise this DA signal actually is, and if DA is fast enough to support RPE TD learning. ...
