- Templ (Dependra Goyal’s startup) can be helpful in tracking blood flow data. The goal of Templ is to understand the stimulus patterns of the brain, and once it knows them, it will trigger stimuli that make the blood flow to the top of the brain (this differs for different people).
- The games controlled by the brain are simple: we measure the brain stimuli that are triggered when we think “left” and observe what gets activated. We do this multiple times, which allows the model to learn which nerves are triggered when we think “left.” The model then sits between the brain and the game and performs actions with respect to the nerves that are stimulated.
- To understand the data in a person’s brain, we need to tie up that person and ask them to think of their phone password. When they think, we capture the spikes and nerve activity in the brain and decode them to get the actual value. Decoding is different for different people; the variation between people is called calibration (simply fine-tuning the decoding for different people).
- When it comes to VR headsets, it is scary. They have our vision data as well as brain data. They can track how the adrenaline rush changes when I see certain objects and then show us specific ads based on that.
- Working of Dognosis
- We capture the electromagnetic fields that are generated by neurons when they sniff. The electrodes connected to the dog’s brain amplify these signals and send the data to the database. This data is used to train the vision models.
- At scale, an electronic nose can be used to sniff and detect cancer, but it is difficult because it is hard to determine which neurons will be activated. We are also studying how the nose changes and which parts of the brain and nose get activated when sniffing.
- We place electrodes in different positions on the head, where each position in the brain has a name, such as Fz, Cz, P3, P4, etc.
- After capturing the data, we get EEG graphs. The distorted signals in them indicate the places where the dog sniffed an anomaly (different kinds of signals).
