Which one of these is scientific term for "Brain Freeze"?

The story behind the answer

Sphenopalatine ganglioneuralgia is the medical term for “brain freeze” or ice-cream headache. It describes pain (neuralgia) originating from the sphenopalatine ganglion, a nerve center behind the palate. Rapid cooling and rewarming of the roof of the mouth cause blood vessels to constrict and then dilate, triggering the trigeminal nerve and producing sharp forehead pain. Pressing your tongue to the palate or sipping something warm can help it pass faster.

Remember it by breaking the word down: “spheno” (near the sphenoid area), “palatine” (palate), “ganglio” (nerve cluster), “neuralgia” (nerve pain). The other options are organism names: Amblyomma americanum (lone star tick), Amaranthus retroflexus (redroot pigweed), and Hyacinthoides italica (Italian bluebell), not headache terms.
