Slow-wave sleep is correlated with memory performance but does not prevent dementia symptoms or serve as a reliable protective measure.

3 days agoPsychology says the people who find it hardest to be taken care of when they're sick aren't independent, they're carrying a very old belief that needing someone was the fastest way to be left - Silicon Canals
Needing care from loved ones during illness can evoke feelings of vulnerability and discomfort, often rooted in deeper fears of abandonment.
Writing

5 days agoNobody talks about why people who grew up writing everything down by hand often struggle with processing their own feelings, and it's because writing things down by hand was how they metabolized emotion, and nobody told them that typing doesn't do the same thing - Silicon Canals
Handwriting engages the brain more deeply than typing, facilitating emotional processing and cognitive engagement.

Microgravity affects astronauts' motor skills, balance, vision, heart shape, and brain position, highlighting the need for understanding these changes for future space exploration.

Focal white matter lesions accumulate with age in the central nervous system and, in neurodegenerative conditions, their number correlates with cognitive and physical impairment. Multiple sclerosis is a demyelinating disorder characterized by white matter demyelinating lesions, while grey matter microgliosis and synaptic loss lead to irreversible neurodegeneration, thought to be the dominant mechanism underlying disability progression.

Subjective age significantly influences brain health, with younger feelings correlating to healthier brain structures.

1 week agoNeuroscience reveals that the calmest person in any crisis isn't naturally fearless - their brain learned to delay panic because their childhood required them to be functional before they were allowed to be afraid - Silicon Canals
Calmness under pressure is a learned response, not merely a personality trait or temperament.

Artificial intelligence (AI) machine learning is making a difference in assistive technology to help restore movement for the paralyzed. A new study in the American Institute of Physics journal APL Bioengineering shows how AI has the potential to restore lower-limb functions in those with severe spinal cord injuries (SCIs) by identifying patterns in brain signals captured noninvasively via electroencephalography (EEG).

1 month agoWhen Even a Neuroscientist Feels Overwhelmed
Modern crises create a 'Traumademic' where overlapping global and personal stressors trigger emotional hijacking, causing the ancient feeling brain to override rational thinking through constantly activated alarm systems.

2 months agoWhen Memory Worries Deserve Attention
Most people will forget a name, misplace their phone, or lose track of a conversation at some point. Usually, those moments pass without much thought. But for many adults, especially as they age, small lapses can trigger a much deeper fear: Is this the beginning of cognitive decline? As a neurologist, I hear this concern often. And as a researcher, I have learned something important: Worry about cognition and cognitive disease are not the same thing.

Anyone living with schizophrenia understands the true limitations of current treatment options. Antipsychotics remain the single leading treatment for the disorder, and they are riddled with undesirable side effects. Weight gain, tardive dyskinesia, and excessive drowsiness are a few. Much research is devoted to expanding the range of medication options, and few academics have pursued other avenues. However, there is a possibility that treatment for schizophrenia can be approached through cellular methods if long-term research validates early signs of hope.

Neuroscientists have a name for the brain network that fires up when you're not focused on an external task: the default mode network, or DMN. It's the constellation of regions - the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus among them - that hums to life when you daydream, reflect on yourself, or think about other people's mental states.

2 months agoAre Frontal Lobe Breakups Real?
There are lots of reasons why relationships fall apart; all kinds of incompatibilities can doom romance. Some are trivial, but occasionally there might be something more profound at the root of an estrangement. Recently, the concept of the "frontal lobe breakup" appeared in popular culture. The idea is that the final stage of development in the executive regions of the brain-the frontal lobes-changes someone's perspective about their relationship. The onset of advanced cognitive skills in one partner creates a gap in maturity too big to bridge.
