Human brain capabilities and recognition of deep fake technology

According to researchers from University College London, humans can only detect artificially generated speech 73% of the time. English and Mandarin speakers demonstrated that level of accuracy. Sound samples created with generative AI and resembling the voices of real people were played back to over 500 study participants. Researchers from the University of Pennsylvania tested how many groups of dots people can distinguish in one second. During the experiment, more than 400 participants distinguished groups of 30 dots from groups of 20 dots with almost 100 percent success. With groups of 20 and 21 dots, people were right almost 60% of the time, and with groups of 50 and 51 dots – 51% of the time.

According to the University of Arizona experts, simply remembering events can trigger brain waves (oscillations) stronger than when experiencing the event. Researchers focused on theta oscillations that occur in the hippocampus during sleep and spatial-time orientation. These discoveries may help treat cognitive disorders and improve the memory of patients with brain damage, cognitive disorders, Parkinson’s disease or after a stroke. The results of a study conducted at the University of California, Irvine, in turn, proved that the smell from a diffuser lingering in the bedrooms of older adults for two hours every night for six months increased the cognitive abilities of the subjects by 226% compared to the control group. It’s an easy and non-invasive memory enhancement technique that potentially staves off dementia.
