Telemetric devices have been developed for wireless electrophysiological recordings to increase the flexibility of the recording situation 10, 11. Nevertheless, cable-based systems often impose problems to conduct studies, e.g., during the transfer of an animal from one cage to another, hindrance or entanglement of the animal with the cables is observed. Some solutions to this problem have been developed e.g., the use of cables and swivel-devices that allow animals to move freely in the arena. There are several systems intended to integrate behavioral recordings with other measurements as neural activity 4, 5.Īlthough electroencephalography is considered one of the most widely used techniques in the field of clinical and research neuroscience, the relatively high mobility, as well as the size of the EEG recording device, makes this technique unique and challenging for detection in case of in vivo models 9. Therefore, synchronized recording of behavioral and neuronal activity at the desired scale (from neurons to large areas of the brain) is considered as an extremely useful tool. If neuronal activity and behavioral patterns could be simultaneously recorded through multiple timescales, they could explain how each brain state correlates to each particular behavior (for a more in-depth examination of behavioral recording, see Datta et al., 2019 review 8). Behaviors are a sequence of minor components that could reveal correlates between the neural activity and movements or actions.
Simultaneous recording of neuronal activity (from single cells to the major brain areas) and behavioral tasks could show us how the brain generates specific behavioral patterns 8. A more potential feature in the behavioral recording area is to explore neural activity during the behavioral manifestation. Video tracking is a valuable method for quick and accurate behavior recording used in a wide variety of applications 7.

Even though some efforts have been made to develop free and open-source software for behavior registration (e.g., sexrat male 2 app for sexual behavior), several alternatives allow the automatic and real-time behavioral recording of different animal species from fish 3 to rodents 4, 5, 6.

Manual recording of behavioral tests might be difficult, exhausting, and inaccurate even for most expert observers. In this regard, researchers have been widely using different behavioral tests to analyze sensory-motor function, social interactions, anxiety-like and depressive-like behavior, substance dependence and various forms of cognitive functions 1. In this manuscript, we have discussed electrodes manufacturing process, epidural electrodes implantation surgery, environmental enrichment protocol, NORT protocol, BTS setup, EEG – BTS coupling for simultaneous monitoring in real-time, and EEG data analysis based on automatic events detection.īehavioral test is crucial in neuroscience research for a large amount of information generated in an in vivo context. The analysis of the EEG synced with behavioral data consists of estimations of alpha and beta relative band power and comparisons between novel object recognition versus familiar object exploration, between three experimental stages. Exploration time for each object was monitored by a behavioral tracking software (BTS) and EEG data recording. After 2 h and 24 h, one of the objects was replaced with a novel one. NORT protocol consists of exposing the animal to two identical objects for 10 min. Six skull screw electrodes were fixed in pairs on both hemispheres over frontal, central, and parietal regions and were referenced to an electrode located posterior of the nasal bone.
Subjects consist of adult Wistar rats after medium-term environmental enrichment treatment.

Both recordings were analyzed offline by their timestamps which were synched to link EEG signals with the animal’s actions.
The animal’s behavior was monitored simultaneously by a video tracking system. In this study, EEG was recorded with a wireless electrophysiology device along with the execution of a novel object recognition task (NORT). However, most of the equipment required to perform both studies are either complex, expensive, or uses a wired setup network that hinders the natural animals’ movement. Therefore, the simultaneous monitoring of behavioral changes and EEG is particularly interesting in correlating data between brain activity and task-related behaviors. Traditionally, researchers used to assess learning and memory parameters in rodent models by behavioral tasks. Adult neurogenesis mechanism is also linked to memory and learning improvement. Brainwaves amplitude obtained from electroencephalography (EEG) has been well-recognized as a basis for cognitive capacity, memory, and learning on animals and humans.
