Aw fuck I havent posted art of her in forever actually. Not a symptom im sure.

Some low effort doodles from like 20 minutes ago

I know that it's just a stylistic choice of the artists for the games, HOWEVER I love that Rayman has one pupil bigger than the other so often. I like to think he has anisocoria, I never see that represented in ocs or fav characters. My great aunt has it which is kinda neat. (The harmless kind) The ray3 model it's barely noticable, but it IS there, his left pupil is a bit smaller, and 'normally' shaped. I also love that they love giving Rayman eyelashes.

turns out

The interaction between the trigeminal nerve (controlling jaw muscles) and the sympathetic nervous system (governing fight-or-flight responses, including pupil dilation) is a central mechanism in stress-related jaw clenching and bruxism. High-stress situations cause a cascade where the brainstem activates both systems simultaneously, leading to a "brace for impact" response that manifests as tight, sustained contraction of the masseter and temporalis muscles. [1, 2, 3, 5]

Specific Interactions in Stress

Microarousals and Clenching: Over 80% of sleep-related jaw clenching occurs during brief awakenings (microarousals) that are initiated by a surge in sympathetic activity (increased heart rate/blood pressure).

Trigeminal-Cardiac Reflex (TCR): Intense clenching can stimulate the Trigeminal Cardiac Reflex, which can lead to a sudden sympathetic-parasympathetic switch that briefly slows the heart rate, a potential, albeit paradoxical, response to stress.

Physical Feedback Loop: The trigeminal nerve receives proprioceptive data from the temporomandibular joint and jaw muscles. Intense clenching sends increased sensory feedback to the brain, maintaining the sympathetic "fight or flight" response. [1, 2, 3, 4]

Key Takeaways on Clenching

Sustained Tension: The jaw often does not just react to stress; it maintains it through a continuous feedback loop from the masseter muscles to the brainstem.

Symptoms: This neuro-physical interaction is often seen in individuals with temporomandibular disorders, leading to headaches, jaw pain, and facial muscle tension.

Management: Techniques that calm the sympathetic system (e.g., deep breathing) also serve to reduce trigeminal nerve activity, helping to relax the jaw. [1, 2, 4, 5]

Clenched teeth and severe jaw tension (TMJ disorders) can cause the pupils to be two different sizes, a condition known as anisocoria. [1, 2]

This occurs due to a neurological connection where the trigeminal nerve (which controls jaw muscles) and the sympathetic nervous system (which controls pupil dilation) interact, particularly during high-stress clenching. [1, 2]

How Clenching Affects Pupil Size

Muscular-Nerve Interaction: The masseter muscles (jaw muscles) used for clenching are connected to a network of nerves, including those regulating the eyes.

Asymmetry: If you clench more heavily on one side, it can lead to unbalanced muscular tension, causing one pupil to appear larger or smaller than the other.

Autonomic Dysfunction: Chronic clenching can dysregulate the sympathetic-adrenergic system (part of the autonomic nervous system), leading to ineffective stress responses and pupil imbalances.

Reversible: In many studies, this type of pupil asymmetry was reduced when an orthotic (bite) correction was used to align the jaw.

Whats up with first 3 barbie movies and the princes with anisocoria

Tbf Stefan and Daniel have scenes were their pupils are similarly sized but eric always has one larger pupil maybe its the lighting

But here the light is on the right and his pupil is still dialeted. To be fair if this was intentional kinda at least makes his design looks interesting... still very disappointing after the whole movie with nutcracker who is like jdhsgdhs smash

For daniels case he has scenes where his pupils are the same size

But stefan sometimes has the dialeted pupil even when that eye is not in the shadow.

Like the funny thing is I am 20 ive been watching these movies my whole life they are all older than me and I just noticed this. And ive seen no one else point this out ever.

Also not me realizing not all first barbie movie men were the same wow

Ampoo is all jollied up bc it's the chrismas and he is loved

(he took them off after the pic bc he tries to be careful with his electricity, and he doesn’t wanna burn the little hats)

*IMAGE ID BELOW IN CASE THE ONE IN THE IMAGE DOESN'T WORK*

[IMG ID: Crudely drawn ms paint fanart of Ampoo, a boy with a purple electrical plug for a head, wearing his long sleeved purple and pink striped shirt.

He is looking up because he has little santa hats covering both of his prongs.

He is putting his hands together and has a big smile on his face. He is also blushing.

One of his eyes is dilated. He is surrounded by white sparkles on a pastel baby blue background. /IMG ID]

apparently I have anisocoria and never noticed until I thought I was getting a concussion from my recent wreck ¯\(°_o)/¯
