A new study has now revealed how knowing beforehand what to look for, helps in our visual search process. Previews – bits of information available in advance, are shown to accelerate our search process as the brain can differentiate and identify the object we are looking for, even among a large set of identical objects. This discovery throws some light on the neurological process responsible for visual search and recognition.
The study from IISc found a previously unidentified yeast-like symbiont inside the lac insect Kerria lacca, which gives the insect its distinctive red colour and, may also provide other nutrients in return for shelter.
