This latest research builds on the pioneering use of machine learning algorithms with brain imaging technology to “mind read.” The findings indicate that the mind’s building blocks for constructing complex thoughts are formed by the brain’s various sub-systems and are not word-based.  Image is credited to Carnegie Mellon University.

Researchers report they can use brain activation patterns to identify complex thoughts. Their findings suggest the building blocks for complex human thoughts are not word based, but formed by the brain’s sub systems. The study provides evidence that the neural dimensions of concept representation are universal across people and languages.

A new study considers how echolocation can benefit visually impaired people to navigate safely through the environment.

Neuroscientists have used a classic branch of maths in a totally new way to peer into the structure of our brains. What they’ve discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions.

People tend to change the pitch of their voice depending on who they are talking to, and how dominant they feel, a new study has found.

Researchers have identified a network of neurons that plays a vital role in learning vocalizations by aiding communication between motor and auditory regions of the brain.

A new study reinforces the idea that serotonin, a molecule associated with mood, directly contributes to the actions of cocaine.

A new report published by the National Academies of Sciences, Engineering, and Medicine shows evidence supporting three interventions for cognitive decline and dementia—cognitive training, blood pressure management for people with hypertension, and increased physical activity, which might slow down cognitive decline and the onset of dementia.

Therapies to change the bacteria in the gut, through diet, pro-and prebiotic supplements, faecal matter transplants or antibiotics, could treat autism.

Finally this week, researchers say a protein usually associated with the immune system could play a role in the development of neurological conditions such as epilepsy and schizophrenia.
