Brain changes linked to decreased anxiety following attention bias modification training

Posted by in category: neuroscience

A new study has identified neuroplastic changes in brain structure that accompany attention bias modification training in highly anxious individuals. The findings, which appear in the journal Biological Psychology, shed light on the mechanisms underlying the efficacy of the treatment.

Research has demonstrated that the brain prioritizes threating information over non-threatening information. But in highly anxious individuals, this attentional bias can become exaggerated and detrimental. The authors of the new study sought to better understand the changes in brain structure that result from attention bias modification, an intervention that seeks to systematically train attention away from threatening stimuli and toward neutral stimuli.

“Our lab has had a longstanding interest in understanding the behavioral and neural mechanisms of affective attention and attentional bias to affective information,” said study authors Josh Carlson and Lin Fang of the Cognitive x Affective Behavior & Integrated Neuroscience (CABIN) Lab at Northern Michigan University.

Body vs. Brain: Scientists Discover Evidence for an Autoimmune Cause of Schizophrenia

Posted by in categories: biotech/medical, neuroscience

Scientists identify an autoantibody that may cause schizophrenia in some individuals. Researchers from Tokyo Medical and Dental University (TMDU) have discovered that some people with schizophrenia have autoantibodies—which are made by the immune system and recognize the body’s own proteins, rat…

Neuronal Cell Type for Controlling the Flow of Information in the Brain Discovered

Posted by in category: neuroscience

By briefly inhibiting other cells, neurogliaform cells in the CA1 region of the hippocampus ensure that current perception and memories of past experiences can be processed both separately and in combination with each other.

Type 3 diabetes: symptoms, causes and treatments

Posted by in categories: biotech/medical, neuroscience

The term ‘type 3 diabetes’ has been used by some to describe Alzheimer’s disease.


While most of us are familiar with type 1 and type 2 diabetes, you may not have come across the term ‘type 3 diabetes’ before. First things first, this is not to be confused with type 3c diabetes, which is something else entirely. It is, however, related to insulin resistance in the brain.

Being diagnosed as insulin resistant generally means that someone is either prebiabetic or has type 2 diabetes. But scientists have proposed that it can also result in the brain’s neurons lacking glucose, which is needed for proper function, and this can lead to symptoms of Alzheimer’s disease.

This map shows which US lakes contain brain-eating amoebas

Posted by in category: neuroscience

The CDC has released a map that shows where brain-eating amoebas are infecting people in lakes across the U.S.


A few days ago, a Missouri resident who went swimming in the Lake of Three Fires in Taylor County, Iowa, was hospitalized after a microscopic amoeba entered through their nose and started eating away at their brain.

Better known as Naegleria fowleri, the single-celled organism that thrives in warm freshwater, travels up the nose to the brain where it rapidly multiplies and begins feasting on brain tissue. It can infect people when they are swimming or diving, by entering through their nose.

Daily Temperature Rhythm in The Human Brain Predicts Survival After Brain Injury

Posted by in categories: biotech/medical, neuroscience

Patients undergo interventions to achieve a ‘normal’ brain temperature; a parameter that remains undefined for humans. The profound sensitivity of neuronal function to temperature implies the brain should be isothermal, but observations from patients and non-human primates suggest significant spatiotemporal variation. We aimed to determine the clinical relevance of brain temperature in patients by establishing how much it varies in healthy adults.

We retrospectively screened data for all patients recruited to the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) High Resolution Intensive Care Unit Sub-Study. Only patients with direct brain temperature measurements and without targeted temperature management were included. To interpret patient analyses, we prospectively recruited 40 healthy adults (20 males, 20 females, 20–40 years) for brain thermometry using magnetic resonance spectroscopy. Participants were scanned in the morning, afternoon, and late evening of a single day.

In patients (n = 114), brain temperature ranged from 32.6 to 42.3°C and mean brain temperature (38.5 ± 0.8°C) exceeded body temperature (37.5 ± 0.5°C, P 0.0001). Of 100 patients eligible for brain temperature rhythm analysis, 25 displayed a daily rhythm, and the brain temperature range decreased in older patients (P = 0.018). In healthy participants, brain temperature ranged from 36.1 to 40.9°C; mean brain temperature (38.5 ± 0.4°C) exceeded oral temperature (36.0 ± 0.5°C) and was 0.36°C higher in luteal females relative to follicular females and males (P = 0.0006 and P 0.0001, respectively). Temperature increased with age, most notably in deep brain regions (0.6°C over 20 years, P = 0.0002), and varied spatially by 2.41 ± 0.46°C with highest temperatures in the thalamus. Brain temperature varied by time of day, especially in deep regions (0.86°C, P = 0.0001), and was lowest at night. From the healthy data we built HEATWAVE—a 4D map of human brain temperature.
