Mating proximity blinds threat perception. https://www.biorxiv.org/content/10.1101/2024.04.23.590677v1?med=mas

“Romantic engagement can bias sensory perception. This 'love blindness' reflects a common behavioral principle across organisms: favoring pursuit of a coveted reward over potential risks.”

“we discover a dopamine-governed filter mechanism in male Drosophila that reduces threat perception as courtship progresses. We show that during early courtship stages, threat-activated visual neurons inhibit central courtship nodes via specific serotonergic neurons. This serotonergic inhibition prompts flies to abort courtship when they see imminent danger. However, as flies advance in the courtship process, the dopaminergic filter system reduces visual threat responses, shifting the balance from survival to mating.”

I feel like I cannabis has a very different effect on me than it does on most people; it never made me hungry, if anything it made me put off eating. After quitting I started eating a lot more regularly and gaining weight. I just used it to make boring things interesting, something I now use amphetamines for.

I've been thinking about gamifying the process of making new friends in my city. Kind of like a but your character is just yourself, and you earn points for showing up to small group events. Extra points for helping organize gatherings and coming up with creative ideas for people to get to know each other better.

...I've been thinking about this for over a year, maybe someday I'll have enough energy to actually start it.

Impact of social media and instant messaging apps on interpersonal relationships

My Perspective

Instant messaging apps like WhatsApp, Telegram Messenger, Signal Messenger etc. (primarily WhatsApp in India) do boost one to one connectivity among friends, acquaintances and family members. It also helps improve communication related to mostly once in a while transactional and sometimes friendly topics like family matters, medical, school and college education, fun side of personal life through photos and videos. Jokes and memes, through forwards, add spices to one to one communication. Group chats and social media like Facebook and Twitter strongly influences one to one communication through instant messengers.

There is another side of instant messaging i.e. the not so nice aspects. Dopamine is a brain chemical that plays a vital role in mood regulation of human beings. It seems that entire society is driven by the feel good factor due to constant availability of cheap dopamine through group chats and social media. Unless it is transactional or related to business, most one to one chats survive as long as the recipients gets positive social stimulus and dopamine influx. It doesn’t matter if something is good or healthy for us, as long as we get that quick dopamine fix.

From my experience of chatting since the days of Yahoo! Chat, I see that loss of reward stimuli and dopamine activity lead to one or both the recipients disengage at the slightest pretext. Read receipts, online status, last seen status etc. further add to anxiety and feeling unimportant or betrayed. There is lack of patience and empathy. Sharing contrarian or critical views, on matters connected to society and politics, often cause functional impairment and getting ignored or blocked.

Interesting note for Fediverse/Mastodon users: you do not get a "view" count here, which makes some new folks (ie journalists/others) feel like they aren't being seen, even though their message is being read by lots of people. They only see the boosts and stars... So hit the "star" button often, especially on new people finally migrating here!

1/8 Today was my first meeting with a new psych from , whom I was referred to after my plea to mental healthcare mgmt. My hope was that this was going to be a discussion leading to formal , but this doesn’t seem to be the case so far.

Within the first 20 minutes, I was told it’s common for parents to erroneously self-diagnose. He felt the same way after caring for his AuDHD child, he said.

2/8 I shared many examples from my life. Social, executive, and anxiety intertwined. I didn’t expect a quick judgement, but seeking formal assessment.

He agreed I have “markers” and recommended breathing exercises, to avoid retriggering trauma and anxiety, to increase levels. In a few weeks we could talk about signing up for an class. Does this mean I was heard? It felt like a deflection.

I see; not healthy.

Recent brain research shows that you can only work 60 min. in one go with full effectiveness.
Then, the brain needs a break to reflect.
If you can, take a short walk and maybe a small snack you like; , baby. 😉
If you don’t comply, you might get a "middle finger" by your 🧠.

BTW, if you manage to relax, your subconscious might even reward you with some solutions or creative 💡s.

Sweated blood yesterday and today trying to fill out just two more pages of necessary paperwork, and took several breaks in between to cover our freshly-mown front lawn with cardboard as the first step to grass replacement.

The latter was definitely more satisfying, and easier to measure the progress of.

Dopamine – The Secret Ingredient to Effortless Exercise?
A study led by Johns Hopkins Medicine researchers suggests that dopamine, a brain chemical associated with pleasure and motivation, plays a critical role in how people perceive the amount of physical effort required for a task, especially in people with Parkinson’s disease, a condition characterized by dopamine deficiency.
