Disclosed is a composition containing 2′-FL for ameliorating, preventing or treating diseases caused by reduction of dopamine. 2′-FL has an advantage of effectively preventing or treating diseases caused by a decrease in dopamine by effectively suppressing degeneration of dopaminergic neurons. In particular, the composition of the present invention is effective in preventing, treating, or ameliorating Parkinson's disease caused by reduction of dopamine because it contains 2′-fucosyllactose (2′-FL) as an active ingredient, thereby suppressing the decrease in dopaminergic neurons and exhibiting an effect of improving motor activity.

The self-administration device is a standard chamber for laboratory mice designed to simulate the injection of addictive substances in humans. This device has two parts: hardware and software. The hardware part includes five structures: the chamber, the infusion pump, the food dispenser, the stimulator, and the controller (interface). The software part controls the hardware parts and records events automatically. The chamber has three keys, each of which can be assigned to one of the effectors. To do this, we define in the device software that pressing one key by the animal activates the infusion pump, another key activates the feeder, and the third key does nothing in particular so that the animal's overall motor activity can be measured with it. Above each key, there is an indicator lamp that, if programmed in the software, lights up each time the animal presses that key, signaling to the animal that the drug is being injected or that the truffle has been deposited in the bowl. In this way, in the long term, the animal learns which key to press if it wants to inject itself with a drug, and which key to press if it wants to eat a truffle. In this way, the state of addiction to substances or food, as well as their interactions and the neural mechanisms associated with them, can be studied.

Techniques are described for controlling a robotized orthosis based on one or more machine learning models trained with input data produced by sensors during motion of test subjects. Examples of such techniques include collecting raw data and / or post-processed spatiotemporal and kinematics data of a test subject's limbs using sensors while the subject is performing motion activities. The prediction of kinematic behavior of a patient may allow a robotized orthosis to compensate for backlash and / or a slow response by anticipating the motion of the patient. A machine learning model(s) may quickly predict, based on the input data, how the patient will move and provide power to the robotized orthosis to support this movement. As a result, the robotized orthosis may be more comfortable for the patient to use.
