An Israeli startup, Hemispheric, says its Descartes AI uses a sensor-cap brain-wave test to diagnose a wide range of neurological and psychiatric conditions in about 15 minutes, aiming for FDA alignment and the ability to run tens of thousands of tests annually across multiple sites, with PTSD trials planned.
NASA’s Voyager Golden Record carries a minute-long compressed recording of Ann Druyan’s brainwaves and heartbeat from 1977, recorded just after she and Carl Sagan agreed to marry. The clip, intended as a life-sign, sits alongside music, greetings and diagrams as a public time capsule, but it also preserves a private emotional moment that science cannot fully decode. As Voyager travels beyond 25 billion kilometres from Earth, the minute remains a human touch embedded in a machine, a reminder that our messages carry both data and intimate feeling into the cosmos.
The Voyager Golden Record includes an hour-long recording of Ann Druyan’s brainwaves and heartbeat, compressed into a one-minute track created in 1977 to guide thoughts about Earth’s history, civilization, and her love for Carl Sagan. Druyan intended it as a private meditation that could hint at inner life to any future listener, perhaps alien; today, neuroscience would say such thoughts are unreadable without the full context. The piece frames a hopeful, human, interior moment encoded for interstellar travel as Voyager 1 and 2 sail onward through interstellar space.
A 20-minute cycling session in epilepsy patients produced a rapid surge of hippocampal-cortical ripples, providing the first direct human evidence that a single workout instantly engages memory and learning networks; the neural pattern matches data from healthy adults, suggesting a general brain response to exercise.
A 2022 study recorded the first human brain waves during dying, showing patterns similar to memory flashbacks, which supports theories about consciousness and memory during death. The article also explores personal experiences with unconsciousness, anesthesia, and near-death states, highlighting the complex and mysterious nature of the dying process.
A study published in Advanced Science reveals that listening to rhythmic sounds causes the brain to dynamically reorganize its networks in real time, with the use of a new method called FREQ-NESS that maps brain activity by isolating specific frequencies, offering new insights into neural plasticity and potential applications in mental health and brain-computer interfaces.
A recent study confirms a 50-year-old theory that auditory hallucinations in schizophrenia are caused by misattributed inner speech, with brain activity patterns showing that affected individuals' brains react as if their internal voices are external, potentially aiding early diagnosis and intervention.
A study by UNSW Sydney psychologists provides strong evidence that auditory hallucinations in schizophrenia may result from a disruption in the brain's ability to recognize its own inner voice, with potential implications for early diagnosis and treatment.
A new study using magnetoencephalography and the FREQ-NESS algorithm reveals how musical rhythms instantly reconfigure brain activity, showing dynamic shifts in brain networks and oscillations in response to rhythmic sounds, with potential applications in clinical and therapeutic settings.
A study from Johannes Gutenberg University Mainz reveals that the brain's ability to synchronize theta waves in the midfrontal region is linked to higher cognitive abilities, especially during demanding tasks, and that this neural coordination is flexible and adaptable, resembling an orchestra following a conductor.
A new neuroimaging method called FREQ-NESS reveals that the brain dynamically reorganizes its networks in real time in response to rhythmic sounds, offering high-precision mapping of brain activity across frequencies with potential applications in neuroscience, perception, and mental health diagnostics.
A study from the University of Montreal found that caffeine increases brain activity complexity and criticality during sleep, especially in younger adults, by altering sleep rhythms and promoting a more alert brain state at night, which may impair sleep recovery and cognitive functions.
Researchers have developed a temporary, wearable 'e-tattoo' that monitors brain activity to assess mental effort in real-time, potentially improving workplace safety and wellbeing, especially in high-stakes professions. The device uses EEG and eye movement tracking, is affordable, and aims to provide continuous mental workload data, unlike traditional post-task questionnaires.
A study by the University of South Australia reveals that sleep significantly enhances language learning by coordinating brainwave patterns during NREM sleep. Participants who slept after learning a new language performed better than those who stayed awake, suggesting that sleep aids in memory consolidation. These findings could inform treatments for language impairments and improve educational strategies.
Scientists at the University of Texas at Austin have developed temporary electronic tattoos that can non-invasively monitor brain activity, potentially revolutionizing EEG testing and brain-computer interfaces. These e-tattoos use a specialized liquid ink that can be applied to the scalp, even through hair, and provide stable readings for up to 24 hours. This innovation could make EEGs more convenient and comfortable, reducing the need for cumbersome equipment and wires, and may also enhance brain-computer interface devices by eliminating the need for bulky headsets.
