Virtual Reality Could Soon Include Smells Thanks to New Wireless Scent Interface

Posted by in categories: food, neuroscience, virtual reality

But they’re not the only ones. Multiple companies are working on haptic devices, like gloves or vests, to add a sense of touch to virtual experiences. And now, researchers are aiming to integrate a fourth sense: smell.

How much more real might that peaceful meadow feel if you could smell the wildflowers and the damp Earth around you? How might the scent of an ocean breeze amplify a VR experience that takes place on a boat or a beach?

Scents have a powerful effect on the brain, eliciting emotions, memories, and sometimes even fight-or-flight responses. You may feel nostalgic with the cologne or perfume a favorite grandparent wore, comforted by a whiff of a favorite food, or extra-alert to your surroundings if it smells like something’s burning.

Researchers present an unsupervised learning-based optical fiber imaging system

Posted by in categories: biotech/medical, neuroscience

Fiber-optic imaging methods enable in vivo imaging deep inside hollow organs or tissues that are otherwise inaccessible to free-space optical techniques, playing a vital role in clinical practice and fundamental research, such as endoscopic diagnosis and deep-brain imaging.

Recently, supervised learning-based fiber-optic imaging methods have gained popularity due to their superior performance in recovering high-fidelity images from fiber-delivered degraded images or even scrambled speckle patterns. Despite their success, these methods are fundamentally limited by their requirements for strictly-paired labeling and large training datasets.

The demanding training data requirements result in time-consuming data acquisition, complicated experimental design, and tedious system calibration processes, making it challenging to satisfy practical application needs.

Glutamatergic synaptic input to glioma cells drives brain tumour progression

Posted by in categories: biotech/medical, neuroscience

Deeply fascinating paper wherein Venkataramani et al. describe how synaptic inputs from neurons onto glioma tumor cells induce electrical activity in the tumors and stimulate their growth and invasiveness. This knowledge could lead to new treatments involving inhibition of the synapses onto gliomas which might provide hope for fighting an otherwise largely incurable form of cancer. #neurobiology #oncology #cancer #medicine

Neurons form glutamatergic synapses with glioma cells in mice and humans, and inhibition of AMPA receptors reduces glioma cell invasion and growth.

Psychedelic substance 5-MeO-DMT induces long-lasting neural plasticity in mice

Posted by in categories: biotech/medical, engineering, neuroscience

The psychedelic substances 5-MeO-DMT causes a long-lasting increase in the number of tiny protrusions called dendritic spines in the brain, according to new research published in Neuropsychopharmacology. The study, which was conducted on mice, sheds light on the behavioral and neural mechanisms of 5-MeO-DMT.

Serotonergic psychedelics (such as psilocybin and LSD) have shown promise as potential therapeutics for mental illnesses like depression and anxiety. Short-acting compounds are particularly interesting because they require less dosing time, which could improve patient access to treatment. In humans, 5-MeO-DMT produces a short-lasting experience due to its rapid breakdown in the body.

“My lab started research on psychiatric drugs like ketamine and psychedelics about 10 years ago. We were motivated by how basic science and clinical research can together powerfully move a drug forward to become medicine. Specifically I believe there is a lot of potential for psychedelics as therapeutics, and that drives our interest in this topic,” said study author Alex Kwan (@kwanalexc), an associate professor in the Meinig School of Biomedical Engineering at Cornell University.

Elon Musk’s brain implant company Neuralink approved for in-human study

Posted by in categories: biotech/medical, Elon Musk, neuroscience


Neuralink, Elon Musk’s brain-implant company, said on Thursday it had received a green light from the US Food and Drug Administration (FDA) to kickstart its first in-human clinical study, a critical milestone after earlier struggles to gain approval.

Musk has predicted on at least four occasions since 2019 that his medical device company would begin human trials for a brain implant to treat severe conditions such as paralysis and blindness.
