Blinking sustains the corneal tear film generated by sexually dimorphic lacrimal and meibomian glands. Our study examines whether trigeminal control of blinking is also sexually dimorphic by investigating trigeminal reflex blinking, associative blink modification, and spontaneous blinking in male and female rats before and after unilateral dry eye caused by exorbital gland removal. Before gland removal, female rats exhibited a lower threshold for evoking trigeminal reflex blinks, a weaker effect of associative blink modification, and longer-duration spontaneous blinks than males.

- Healthy individuals can generally detect biological motion using few moving points, influenced by internal models linked to their movement skills.
- The study aimed to assess whether people with symptomatic Huntington's disease (HD) struggle with perceiving movements compared to healthy individuals.
- Results indicated that those with HD showed reduced accuracy in identifying movements, particularly struggling with stair climbing motions, and did not exhibit performance improvement over time like their healthy counterparts.
Parkinson's disease (PD) patients and the 6-hydroxydopamine (6-OHDA) lesioned rat model share blink abnormalities. In view of the evolutionarily conserved organization of blinking, characterization of blink reflex circuits in rodents may elucidate the neural mechanisms of PD reflex abnormalities. We examine the extent of this shared pattern of blink abnormalities by measuring blink reflex excitability, blink reflex plasticity, and spontaneous blinking in 6-OHDA lesioned rats.
