Topic: auditory stimuli

Information retrieval from brain responses to auditory and visual stimuli has shown success through classification of song names and image classes presented to participants while recording EEG signals. Information retrieval in the form of reconstructing auditory stimuli has also shown some success, but here we improve on previous methods by reconstructing music stimuli well enough to be perceived and identified independently. Furthermore, deep learning models were trained on time-aligned music stimuli spectrum for each corresponding one-second window of EEG recording, which greatly reduces fea

FED3 is a device for behavioral training of mice in vivarium home-cages. Mice interact with FED3 through two nose-pokes and FED3 responds with visual stimuli, auditory stimuli, and by dispensing pellets. As it is used in the home-cage FED3 can be used for around-the-clock training of mice over several weeks. FED3 is open-source and can be built by users for ~10-20x less than commercial solutions for training mice. The control code is also open-source and was designed to be easily modified by users.

Recently, the self has become an important focus of conscious mind research. Neuroimaging studies reveal that the self emerges from the spontaneous activity of cortical midline structures (CMS). Prefrontal cortex structures are also mentioned prominently in consciousness theories such as higher-order and global workspace theories. This preliminary study aims to observe changes in frontal hemodynamics in response to self-related and non-self-related stimuli. The study included five healthy voluntary participants (mean age=25.6±5.986). Auditory stimuli containing the subject's own name (SON) wer
