A wear-type brain electricity bandeau for sheep

Technical Field

The utility model belongs to animal brain electricity collection field relates to a wear-type brain electricity bandeau for sheep

Background

Electroencephalogram signals are one of the important means for studying brain scientific activity and can be used for recording potential activities reflecting excitability and inhibitory postsynaptic potentials of brain scalp neurons. Since the early twentieth century, scientists began using electroencephalography, which records electrical impulses waves in the brain, to study epilepsy and sleep patterns in humans. At present, the electroencephalogram is widely applied, and relates to disease diagnosis of a nervous system and monitoring of human body states. The electroencephalogram signals are widely applied to psychological and behavioral research, such as depression, schizophrenia, attention deficit and hyperactivity disorder, so that the electroencephalogram signals have very important significance in the aspects of researching brain functions, understanding working mechanisms and diagnosing and treating diseases.

Brain damage from blast shock waves is common in military applications, particularly in field assessment trials of weapon killing effects. The commonly used brain injury evaluation methods include pathological observation of brain tissue and examination of brain injury standard substances, including S-100 protein, neuron-specific enolase and the like. These are methods for assessing brain tissue damage, but assessment of cognitive function in a subject is lacking. At present, methods for evaluating the change of the cognitive function of a brain injury patient clinically include methods such as functional nuclear magnetic resonance, event-related potential, electroencephalogram quantitative analysis and the like. However, in field tests, the test sites are often in the field, and the test objects are animals. And nuclear magnetism and other high-consumption and high-price equipment require, a subject cannot move so as to avoid generating artifacts, ERP requires the cooperation of the subject and the feedback interaction capacity, and field tests do not have the conditions. Recently, it has been found that people can find out depression, anxiety and even satisfaction through electroencephalogram. Meanwhile, electroencephalographic studies have migrated from humans to rodents, farm animals, and pets, and revealed that animals respond to various external stimuli. Therefore, in theory, electroencephalograms can capture the mental state of an experimental large mammal. Unfortunately, no method has been found to record the brain waves of an animal as it moves. It is believed that this is because recording the electroencephalogram requires placing electrodes at specific locations on the head and connecting wires from the electrodes to the recorder.

Therefore, the electroencephalogram has the advantages of convenience, rapidness and no need of matching with a tested object, and is suitable for being applied to field evaluation tests. However, a special electroencephalogram system suitable for mammals is not seen for a while through market research and reference of documents. However, in this process, one needs to restrain or force the animal to calm. At the same time, in order to obtain an accurate reading, either the animal's head must be shaved or electrodes surgically implanted under the animal's scalp. These all make the electroencephalogram signal acquisition inconvenient and fast to operate.

SUMMERY OF THE UTILITY MODEL

Further, the electrode placing belt is square, and the electrodes comprise collecting electrodes arranged at four corners of the electrode placing belt and two reference electrodes arranged at the center of the electrode placing belt.

Furthermore, the positions of the four collecting electrodes are arranged at the positions of squares which are around the weak position of the animal skull and have a certain distance from front to back, left to right, and are respectively corresponding to the left frontal lobe, the right frontal lobe, the left parietal lobe and the right parietal lobe of the animal skull.
