Here’s how human brain recalls events




Do you know how we recall a past event? According to a new study, when retrieving information, the human brain reconstructs that experience in reverse order indicating that it focuses first on recovering the ‘gist’ and recalls more specific details later.

The study found that when we initially see a complex object, the visual details — patterns and colours — are perceived first. Whereas, abstract, meaningful information that tells us the nature of the object we are looking at comes later.

“We know that our memories are not exact replicas of the things we originally experienced. Memory is a reconstructive process, biased by personal knowledge and world views – sometimes we even remember events that never actually happened. But exactly how memories are reconstructed in the brain, step by step, is currently not well understood,” said lead author, Juan Linde Domingo, doctoral student at the University of Birmingham in Britain.

The researchers reconstructed the memory retrieval process, using brain decoding techniques which make it possible to track when in time a unique memory is being reactivated in the brain.

During the study, participants saw images of specific objects and then learned to associate each image with a unique reminder word, for example the word ‘spin’ or ‘pull’.

They were later presented with the reminder word and asked to reconstruct the associated image in as much detail as possible.

The findings, published in Nature Communications, showed that the participants retrieved higher-level, abstract information, shortly after they heard the reminder word.

“It suggests they will become more abstract and gist-like with each retrieval,” added Domingo.

The team is currently also looking in more detail at how and where the brain reconstructs more complex memories.


FaceApp Seems to Be Now Blocking Users From India





FaceApp, the photo editing app with age filters that have made the app viral virtually overnight, seems to be now blocking users from India. The app is still available for to download for Android and iOS respectively from Google Play and Apple’s App Store, but trying to use FaceApp from India now leads to error. The FaceApp block was reported by users on Twitter and confirmed independently by Gadgets 360. We’ve reached out to the company behind the app for a comment on the development, and will update this story as and when we hear from them.

If you are on Android and trying to use FaceApp from India, you might now be greeted with an error “Something went wrong, Please try again”. iOS users are getting a more cryptic “ApiRequestError error 6 – Operation couldn’t be completed” message. The problem was first reported by some Twitter users, and confirmed by Gadgets 360.

FaceApp, which uses AI to apply various effects to your face, including the viral old-age filter, has been trending the last few days

Apart from the old-age filter, FaceApp can also “make you smile”, converting a regular photo into one where you are smiling. Similar to the old-age filter, another filter lets you look younger, while yet another FaceApp filter lets you change your style and experiment with different hair styles. With some points in its terms of service raising concerns.

In a separate issue in 2017, FaceApp was found to have a dedicated “hot” filter that looked to “lighten” the skin tone of users. The racist filter was removed after it sparked outrage among many users.
