Animal studies have shown that pregnancy is associated with unique changes in the mammalian brain and behaviour, although pregnancy-associated changes in the human brain are less well studied. Here the authors show that pregnancy is associated with changes in resting state brain activity and brain anatomy which are most pronounced in the default mode network.
Neuralink’s invasive brain implant vs phantom neuro’s minimally invasive muscle implant. Deep dive on brain computer interfaces, Phantom Neuro, and the future of repairing missing functions.

Phantom is creating a human-machine interfacing system for lifelike control of technology. We are currently hiring skilled and forward-thinking electrical, mechanical, UI, AR/VR, and Ai/ML engineers. Looking to get in touch with us? Send us an email at [email protected].
Phantom Neuro.
Phantom is a neurotechnology company, spun out of the lab at The Johns Hopkins University School of Medicine, that is enabling lifelike control of robotic orthopedic technologies, such as prosthetic limbs and exoskeletons. Phantom’s solution, the Phantom X, consists of low-risk implantable sensors, AI, and enabling software. By providing superior control of robotic orthopedic mechanisms, the Phantom X will drastically improve the lives of individuals with limb difference who have yet to see a tangible improvement in quality of life despite significant advancements in the field of robotics.

Imagine that you can grow a clone with the level of intelligence below the level of a turkey or a chicken with the perfectly-exercised body. Would you consider swapping your brain with this perfect and unconscious clone? Surprisingly, many professionals would not even think twice.
Successful communication and cooperation among different members of society depends, in part, on a consistent understanding of the physical and social world. What drives this alignment in perspectives? We present evidence from two neuroimaging studies using functional magnetic resonance imaging (fMRI; N = 66 with 2,145 dyadic comparisons) and electroencephalography (EEG; N = 225 with 25,200 dyadic comparisons) to show that: the extent to which people’s neural responses are synchronized when viewing naturalistic stimuli is related to their personality profiles, and that this effect is stronger than that of similarity in gender, ethnicity and political affiliation.
Major depressive disorder is associated with altered interoception — or the ability to sense the internal state of your body. Now, new brain imaging research provides evidence that depressed individuals tend to exhibit “faulty” neural processing of gastric interoception, particularly among those with high levels of rumination. The findings have been published in the Journal of Psychiatric Research.
“Repetitive negative thinking (RNT), usually referred to as ‘rumination’ in persons who suffer from depression, is a very significant clinical problem,” explained study author Salvador M. Guinjoan, a principal investigator at the Laureate Institute for Brain Research and associate professor at Oklahoma University Health Sciences Center at Tulsa.
“The reason is that when it is severe and persistent, RNT conditions higher chances of depression relapse and is associated with residual symptoms after treatment, is more common in persons who do not respond to treatment, and is even related to suicide. This particular communication refers to one among a series of projects in our lab attempting to understand rumination.”

The discovery could lead to potential future targeted therapies and treatments for this brain disorder.
Researchers have found two novel genes that increase an individual’s risk of developing Alzheimer’s disease (AD). This disorder is the leading cause of dementia and has an estimated heritability —genetic factor causing variation in the population, or an inherited trait— of 70%.

Summary: Researchers have identified two new genes, ATP8B4 and ABCA1, that are implicated in Alzheimer’s disease. The genes impact the brain’s immune system and cholesterol processing, leading to an increased risk of developing Alzheimer’s disease.

The ability to link mind and machine has long been the realm of science fiction, but now improvements in our understanding may allow us to network brain to computer in the near future. Companies like Neurolink have begun to explore how to link our neurons to machine, and we’ll explore now such neural interfaces might function and how they might change our lives.

This new way to diagnose schizophrenia, epilepsy, Alzheimer’s disease and autism spectrum disorder could help improve mental health. We often think of fingerprints as the tiny ridges, whorls and arched patterns on the tip of each finger. They are heralded as special markers of human identity, even more individualized than DNA.
