I am enjoying reading lots of different introductions over the last days so I will hop on the train as well and introduce myself! 👋

I am a PhD student at the for motivation, action, and desire lab working with @nbkroemer 🧠

I am broadly interested in and in my PhD I am incorporating a metabolic perspective to understand how the influences neural communication, motivation and effort. 🏋️‍♂️

Many psychiatric disorders come along with both motivational and metabolic alterations so the gut-brain perspective might help us to better understand and treat disorders like 🎯

Are reward responses in the human brain modulated by gut hormones?

In our systematic review & meta-analysis, we find converging evidence for enhanced reward signals by ghrelin. For GLP-1, the convergence is too low and might be dependent on the phase (anticipation vs. consummation).

Great work led by @cor_et_cerebrum @cecivez

As a #scientist I think it’s important that we debunk the popular #myths & misconceptions of our fields of research. Having recently joined #Mastodon during the great #TwitterMigration, I’ll try to recreate some of my prior threads on misleading metaphors in #scicomm of #genetics & to adapt them for this platform.

First up: contrary to what you may have heard, your genome is not a blueprint. Read on to find out why...1/6

This is one of my favorite immunopsychiatry papers I've read in a while. Currently, there is so much the disconnect between specificity of theory (e.g., phenotyping + physiometrics) and how intervention trials are designed. We need to close the gap.

The Montreal AI and Neuroscience educational workshop 2022 is over! All the material is online and will remain accessible: basics of machine learning and deep learning, intro to fMRI (with nilearn), intro to M/EEG (with MNE-python), intro to calcium imaging and electrophysiology in animals, two sessions on brain encoding and decoding as well as two keynote lectures on neuroAI. Includes slides & code, videos will follow soon. Huge thanks to the organizing team and speakers main-educational.github.io/mat

And following the #TwitterMigration Now in the right server 😉 Here comes my intro! #neuroscience #neurodon #decisionneuroscience 
Hello everyone! I’m a 4th year PhD candidate focused on decision neuroscience, noninvasive brain stimulation #nibs and the #gutbrainaxis. My research aims at clarifying the neural underpinnings of #risktakingbehavior Check out my work AlineDantas.net and connect!

Hi everyone, just got here from Twitter. I head the Biopsychology Lab at the Psychology Department at University of Cologne.

We use computational and cognitive neuroscience approaches to better understand the mechanisms underlying decision-making and learning.

More specific issues we study include mechanisms underlying problem gambling, and everything dopamine.

So how does this work, I just click "toot"?

Can gastrointestinal hormones modulate our reward responses? @cecivez and I ventured into the available data and literature to find that
🎯 ghrelin enhances reward responses within the motivational circuit! w/ @nbkroemer

Overdue #introduction 👋 
I am a #neuroscientist currently finishing an #NSF postdoc fellowship at #Caltech - starting as an Assistant Professor at #UniversityofMelbourne in 2023.
My work uses #experimental & #computational approaches with #fMRI to study the neural basis of decision making in humans. I focus on how the brain processes information related to #threat & #safety. I examine the development of these systems from #adolescence to #adulthood.
Glad to join the #neuroscience contingent!

Hi tweeps, the U-shape is ubiquitous in psychology. However, it can easily be (mis)used to explain (away) mixed findings too. What is according to you the most robust evidence for (inverted) U-shaped effects in psychology (ideally causal, manipulated within-person)? Pls RT!

Hi Mastodon 🙋🏼‍♀️ I guess it‘s time for an introduction!
I’m Stina and currently working on my in at Gothenburg University in Sweden. My focus: gut-brain communication in eating behavior and emotionality, specifically investigating the influence of and potential .
Besides, I have been communicating science on social media since 6 years now and became a docent in about a year ago.
Looking forward to connecting with you!

#Introduction time! #NeuroscienceMigration

Hungry for compliments? Ghrelin is not associated with neural responses to social rewards or their pleasantness

The stomach-derived hormone ghrelin motivates food search and stimulates food consumption, with highest plasma concentrations before a meal and lowest shortly after. However, ghrelin also appears to affect the value of non-food rewards such as interaction with rat conspecifics, and monetary rewards in humans. The present pre-registered study investigated how nutritional state and ghrelin concentrations are related to the subjective and neural responses to social and non-social rewards. In a cross-over feed-and-fast design, 67 healthy volunteers (20 women) underwent functional magnetic resonance imaging (fMRI) in a hungry state and after a meal with repeated plasma ghrelin measurements. In task 1, participants received social rewards in the form of approving expert feedback, or non-social computer reward. In task 2, participants rated the pleasantness of compliments and neutral statements. Nutritional state and ghrelin concentrations did not affect the response to social reward in task 1. In contrast, ventromedial prefrontal cortical activation to non-social rewards was reduced when the meal strongly suppressed ghrelin. In task 2, fasting increased activation in the right ventral striatum during all statements, but ghrelin concentrations were neither associated with brain activation nor with experienced pleasantness. Complementary Bayesian analyses provided moderate evidence for a lack of correlation between ghrelin concentrations and behavioral and neural responses to social rewards, but moderate evidence for an association between ghrelin and non-social rewards. This suggests that ghrelin's influence may be restricted to non-social rewards. Social rewards implemented via social recognition and affirmation may be too abstract and complex to be susceptible to ghrelin's influence. In contrast, the non-social reward was associated with the expectation of a material object that was handed out after the experiment. This may indicate that ghrelin might be involved in anticipatory rather than consummatory phases of reward. ### Competing Interest Statement The authors have declared no competing interest.
