10 Ways to Increase the Dopamine In Your Brain

“Dopamine is a neurotransmitter that helps control the brain’s reward and pleasure centers. Dopamine also helps regulate movement and emotional response, and it enables us not only to see rewards, but to take action to move toward them.”  – Psychology Today

The funniest, best-sung song by an epigenetic neuroscientist ever!

The singer, Dr. Rachel Yehuda showed that the gene expression of pregnant Holocaust & 9/11 survivors were altered by the experiences, as were those of their children. But here she’s just having fun!

#Thankful for #Science and “Sciencers” #Thanksgiving

I am thankful for science and people who science. Not just because I have epilepsy and without pharmacology I would sporadically behave like an alien breakdancer. I’m not just thankful for the surgeons who implanted my cyborg hip and Alice in my synthetic hip, Trixie. I’m grateful to the material sciences who developed the titanium and ceramic substances to the engineers figure out the exact angle that the implants should good rest most strongly and snugly within. I’m grateful to the immunologist who rigorously test the parts to make sure my body won’t rejecting it.

And again, through my various surgeries, big love to the pharmacologists for the Dilaudid.

I am specifically grateful to those who science human behavior even more acutely, sciencers of the brain for making it easier to forgive people.

You have to struggle to be mad at someone when you realize their argumentativeness may be nothing more sinister than an overactive insula or their lethargy a mere underproduction of dopamine receptors for their appearance heartlessness a not uncommon malfunction in the either the anterior or posterior pituitary.

Studying the effects of brains on human behavior reminds me best we are all born in the bodies we did not design, into a world we did not create having reactions to which on one can explain.

The writer Evelyn Waugh says to, understand all is to condone all. I do not condone all but hey, I’m still studying here.

The Neuroscience of Conversion Optimization – Neuromarketing

[Guest post by Nick Kolenda] If you’re a digital marketer, then you know the feeling. You poured your heart and soul into a recent campaign, and you can’t wait to see the results. A few days later, you check the […]

Believe or not this is also a delightful example and explanation of how brains handle sounds.


#Neuroplasticity and Training the Older Brain #neuroscience #seniorsrock

brail
Neuroplasticity is the brain and nervous systems ability to evolve and to repair deficits.
At a basic level it represents the ability to learn and develop a structural and functional system to interact with the environment.
The brain’s neuroplasticity is maximized during childhood and adolescence. This adaptability wanes with age. However, some neuroplasticity ability persists in the older brain.
This persistence was highlighted in a study from Hong Kong recently published in the journal Neural Plasticity.
Natalie Leung and colleagues studied a group of older adults with an average age of 70 years. Two hundred nine older adults were randomized to a cognitive training protocol or a control video education intervention.
The cognitive training protocol involved three one-hour training sessions for 13 weeks (39 hours total cognitive training). The training in this protocol was adapted from the Brain Fitness Program of Posit Science. Elements including tasks focusing on reaction time, visual discrimination, verbal memory, attention and working memory. All subjects completed neuropsychological assessment at baseline and at the end of the 13-week trial.
The active training groups demonstrated significant improvement in a variety of cognitive domains compared to the control group including:
  • Higher sustained attention scores on the Seashore Rhythm Test
  • Better performance on working memory digit span tasks
  • Better performance on visual-spatial cognition 
This study did not include a brain imaging component. However, the author’s note their findings suggest sensitive imaging tools might complement their results and provide better understanding of structural and functional elements of neuroplasticity in the older brain.
 
The role of brain training in modifying the effects of aging on the brain is still in early stages of research. However, the current study supports the ability of elderly individuals to respond to cognitive training interventions.

#Neuroscience of #Chicago #Cubs Fans – YouTube

C2ST Artist in Residence Aaron Freeman pretends to interview Stanford University Neurobiology professor Robert Sapolsky on the difference between the brains of Chicago Cubs fans and those of lesser beings.  According to Sapolsky part of the difference may have  to do with higher sustained levels of the neurotransmitter dopamine.

When I threatened to shoot Chicago Police #blacklivesmatter

All lives matter. This is a story from long, long ago.

I’ve never shot or shot at any human being. This is the tale of a threatening phone call my mom told me to make in 1969 when I was 13 years old.

I LOVE the police, especially the ones here in Highland Park and Highwood Illinois. I get scared when I see a light top car in my rear view mirror. But when on my front porch with my bride I am reassured to see a marked car cruise by. We always smile and wave.

Why #Neuroscience Needs Hackers

hack

By Daniel Goodwin | Aug 18, 2015 – There was a time when neuroscientists could only dream of having such a problem. Now the fantasy has come true, and they are struggling to solve it. Brilliant new exploratory devices are overwhelming the field with an avalanche of raw data about the nervous system’s inner workings. The trouble is that even starting to make sense of this bonanza of information has become a superhuman challenge.

Just about every branch of science is facing a similar disruption. As laboratory-bench research migrates into the digital realm, programming is becoming an indispensable part of the process. At the same time, previously dependable sources of financial support are drying up. The result has been a painful scarcity of jobs and grants—which, in turn, is impelling far too many gifted researchers to focus on their narrow areas of specialization rather than investing time and energy into acquiring new, computer-age skills. In fields where data growth is especially out of control, such as neuroscience, the demand for computer expertise is growing as quickly as the information itself.

“Visceral disgust” at #allisonbechtel “Fun Home” prob involves the brain’s insula – Insula and Disgust

Cerebral_Gyri_-_Insula

The disgust emotion [which some experience at the very THOUGHT homosexuality, the so-called “ik factor”] is elicited by a variety of stimuli ranging from rotten food to immoral persons. When we encounter such disgusting stimuli, whether they are physical or social, we commonly experience rejection responses by the body such as nausea and revolt. In fact, since the time of Darwin, it has been argued that disgust has its origins in a rejection response to offensive food, and that the sensations of tastes and odors play a crucial role in the experience of disgust. This view predicts that the insula is closely related to disgust because it serves both gustatory and visceral motor functions including the control of vomiting. Indeed, the insula is activated by a broad range of disgust-related stimuli such as disgusted facial expressions, unpleasant odors, pictures of rotten food, and unfair acts. However, increasing evidence indicates that the insula plays an important role in the experience of not only unpleasant but also pleasant bodily feelings. In brief, the insula seems to be involved in the conscious perception of emotional bodily feelings in general, or somatic markers, and assist in our decisions as to approach vs. avoidance.
