Cited by 4 •
2017
This article presents eight different experimental tasks, mirroring the everyday life of dogs and owners, used to analyze how owners interact with their dogs in a standardized way. The tasks included both positive (e.g. play) and negative (potentially stressful) situations (e.g. physical restriction).

Operating Procedures of the Electrochemotherapy for Treatment of Tumor in Dogs and Cats

Electrochemotherapy is the local treatment of solid tumors. The main mechanism is electroporation-mediated permeabilization of the tumor cells' membrane which enables increased internalization of cytostatics like bleomycin and cisplatin. Thus, antitumor effectiveness is potentiated at the site of the application of electric pulses to the tumors.

fMRI: Functional Magnetic Resonance Imaging
0 Views •
2023
Functional magnetic resonance imaging (fMRI) is a non-invasive neuroimaging technique used to investigate human brain function and cognition in both healthy individuals and populations with abnormal brain states. Functional MRI utilizes a magnetic resonance signal to detect changes in blood flow that are coupled to neuronal activation when a specific task is performed. This is possible because hemoglobin within the blood has different magnetic properties depending on whether or not it is bound...

FAQs
The method relies on the relationship between local neural activity and changes in blood flow and oxygen use. These physiological changes alter blood-oxygen-level-dependent signals detected by the scanner. Because the signal reflects this activity-related vascular response, researchers can identify brain regions that respond during a task or sensory stimulation rather than observing neural activity in isolation.
Movement can affect the reliability of comparisons between brain regions or experimental conditions, so researchers must account for motion during data collection and analysis. Animal welfare is equally important because scanning occurs during controlled research procedures. Managing both factors helps ensure that observed signal differences are biologically meaningful and obtained under appropriate conditions for the dog.
Comparing activity across brain regions shows how different parts of the canine brain respond during controlled tasks or sensory stimulation. These patterns can be examined in relation to cognition, perception, and behavior. The approach therefore supports questions about how dogs process information and how coordinated regional responses relate to learning, emotion, or communication.
Behavioral observation records visible actions, whereas the scan provides information about activity patterns in the brain while a dog performs a task or receives sensory stimulation. Using both perspectives can connect an observable response with regional brain changes. This makes the technique valuable for examining internal processing that may not be evident from behavior alone.
Researchers collect scans while the dog undergoes a controlled task or receives sensory stimulation. They then compare blood-oxygen-level-dependent signals across brain regions and account for motion when evaluating the results. The design also incorporates animal-welfare considerations, allowing investigators to relate measured activity patterns to cognition, perception, behavior, or other defined research questions.
Dog fMRI can be applied to studies of learning, emotion, communication, perception, and broader canine cognition. It also contributes to veterinary neuroscience by providing a way to investigate brain function in dogs. The measured regional activity patterns help researchers evaluate how neural responses correspond to specific tasks, stimuli, or behavioral questions.
Canine brain imaging supports comparisons between dogs and other mammalian brains by examining activity patterns during defined tasks or sensory conditions. These comparisons can place canine cognition and behavior within a broader neuroscience context. The results may also help connect findings from veterinary neuroscience with general questions about mammalian brain organization and function.
The technique can be used in veterinary neuroscience to investigate brain function in dogs, including questions related to neurological disorders. Researchers can examine regional activity patterns under controlled conditions and relate them to cognition, perception, or behavior. This provides a noninvasive research context for studying altered brain function alongside broader canine neuroscience questions.
