Researchers perfectly identify a transporter protein in the brain that plays a major role in habituation

How actually vision influences the development of hearing

Habituation is very common in humans and other organisms because it enables them to perfectly pay attention to the most important and essential features in their surroundings. 

Their surroundings food, mates, and danger; while properly and safely ignoring extraneous information. It's really amazing.

Currently, the circuitry in our brain and the molecular mechanisms perfectly involved in habituation are poorly understood.

Researchers step by step investigated these amazing mechanisms by studying the actual ability of fruit flies to tune out a specific scent.

They finally discovered that the choline transporter, a protein that takes up choline into neurons so that the cells can easily produce the neurotransmitter acetylcholine, regulates habituation to smells.

Flight Path

Fruit flies with fewer choline transporters in certain parts of our brain and did not become habituated to the scent, instead became hypersensitive.

The hypersensitivity and other valuable changes observed in the flies with fewer choline transporters are really similar to symptoms seen in people with Autism spectrum disorder.

The study's findings really open new avenues for future research to properly investigate the role of choline transporters in disorders related to habituation.

This amazing work may have far-reaching implications for our actual understanding of several neurological disorders.
