A paralysed man who had an extreme form of locked-in syndrome and heard a nurse say he was “brain dead” has become the first ever to recover after hearing medical professionals debating whether or not to switch off his life support.

In 2017, Jacob Haendel was living a normal life as a head chef in Boston, Massachusetts but in the space of a few weeks, his life was turned upside down after he was diagnosed with acute toxic progressive leukoencephalopathy, which progressed into locked-in syndrome and forced his body would slowly shut down. An extreme form of locked-in syndrome is a condition where a patient is aware but cannot move or communicate verbally due to complete paralysis and can be caused by brain trauma, infection or exposure to toxins.

Perfect balance: How the brain fine-tunes its sensitivity

Posted by in category: neuroscience

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain’s neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. University of Basel researchers report in the journal Nature how neuronal networks in the mouse brain are fine-tuned.

Dysfunction of neurons in the amygdala may be behind negative perceptions of the environment

Posted by in category: neuroscience

One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this “negativity bias,” which can fuel the development of depressive symptoms, had previously remained largely unknown.

Neuroscience sheds light on brain mechanisms underlying exceptional creativity

Posted by in category: neuroscience

A new study sheds light on how highly creative individuals, such as visual artists and scientists, may have brains that function differently compared to others. The research, published in Psychology of Aesthetics, Creativity, and the Arts, reveals that people who exhibit exceptional creativity—referred to as “Big C” creative individuals—demonstrate…

Neuronal wiring’s role in brain function varies across regions, study finds

Posted by in category: neuroscience

Different brain regions are connected by—and interact through—networks of neurons. But the extent to which neuronal wiring drives shared function between these different regions is not well understood. Is this structure-function relationship the same throughout the brain? The same across functions?

Natural compound found in flowers blocks activity of an enzyme involved in multiple sclerosis and cancer

Posted by in categories: biotech/medical, neuroscience

Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclerosis.

Mental Fatigue Triggers Compensatory Brain Mechanisms

Posted by in category: neuroscience

New research reveals that prolonged mental load weakens brain connectivity, but compensatory mechanisms keep cognitive performance steady.


Summary: A recent study shows that prolonged mental exertion weakens connectivity between the brain’s frontal and parietal lobes, impacting cognitive efficiency. However, the brain has built-in compensatory mechanisms that adjust neural connections to preserve function under fatigue.

Researchers observed this in participants completing memory tasks of varying difficulty; while fatigue slowed performance on simple tasks, complex tasks triggered compensatory adjustments. Findings suggest that these mechanisms allow the brain to optimize resources based on task complexity.
