Abstract: Disclosed is a stimulus applying apparatus. A stimulus applying apparatus according to an embodiment of the present invention comprises: stimulus applying units configured to apply a stimulus to a target portion; and a housing coupled to the stimulus applying unit. The housing comprises: a first housing arranged on one side of the target portion and accommodating a stimulus applying unit; and a second housing arranged on the other side of the target portion and accommodating a stimulus applying unit. The stimulus applying unit accommodated in the first housing and the stimulus applying unit accommodated in the second housing may be configured to apply magnetic attractive force to each other.

Abstract: Disclosed is a pain assessment method using a deep learning model, the pain assessment method including operations of receiving, by an analysis device, an image indicating activity in a specific brain area of a subject animal and allowing the analysis device to input images of regions of interest in the image into a neural network model and assess the pain of the subject animal according to a result output by the neural network model.
