Research finds few seizing patients receive EEGs in emergency department

A new study by University of Cincinnati researchers found that only a small proportion of seizure patients receive electroencephalograms (EEGs) in the emergency department, which can lead to delayed or inaccurate diagnoses. The study suggests that this may impact admission decisions and hospital care for these patients.

Your brain 'sees' things even when you don't

Researchers found that the brain processes visual input at a level of understanding its meaning, even if we never consciously perceive it. The study used EEG monitoring to show that participants' brainwaves showed a signature, or N400 waveform, when viewing objects hidden in silhouettes.

Study: Your brain sees things you don't

Researchers found that brainwaves indicate the brain processes and understands hidden objects in everyday life, despite the subjects not consciously perceiving them. The study challenges existing models of how the brain processes visual information, suggesting a more complex role for the brain in interpreting visual input.

'Network' analysis of the brain may explain features of autism

Researchers analyzed EEGs from autistic children and found a structural difference in brain connections, including increased short-range and decreased long-range connections. This pattern may underlie autism's classic cognitive profile of focused tasks but poor integration across brain areas.

Brain regions can take short naps during wakefulness, leading to errors

Researchers at the University of Wisconsin-Madison discovered that certain nerve cells in a sleep-deprived yet awake brain can briefly enter a sleep-like state, negatively impacting performance. This 'local sleep' phenomenon affects specific groups of neurons in the motor cortex, leading to mistakes and decreased vigilance.

US neurologists agree on protocols for treatment of infantile spasms

The US Neurology guidelines provide a framework for diagnosing and treating infantile spasms, with a focus on early intervention and personalized treatment strategies. The consensus among experts is that broad clinical evaluation, vigabatrin or adrenocorticotropic hormone (ACTH) as first-line treatment, and timely assessment of treatme...

Are all meditation techniques the same?

Research categorizes meditation into three types: focused attention (beta/gamma activity), open monitoring (theta activity), and automatic self-transcending (alpha1 activity). Different techniques produce distinct results, and lumping them together can lead to inaccurate interpretations.

Towards zero training for brain-computer interfacing

A novel data analysis method has been developed that extracts representative spatial filters for each individual subject, reducing the need for calibration before every session. This approach may pave the way for practical daily use of brain-computer interfacing technology for both patients and healthy users.

Smoking linked to sleep disturbances

Research shows that cigarette smoking is associated with restless sleep and reduced deep sleep hours, as well as increased light sleep. The study suggests that nicotine withdrawal may contribute to these disturbances, particularly in the early stages of sleep.

New guideline for how to treat a person's first unprovoked seizure

The American Academy of Neurology recommends a routine electroencephalogram (EEG) and brain scans, such as CT or MRI, for adults experiencing their first unprovoked seizure. These diagnostic tools can help identify brain abnormalities that caused the seizure and predict seizure recurrence in approximately one in four patients.

Women with severe PMS perceive their sleep quality to be poor

A study found that women with severe premenstrual syndrome (PMS) report poor sleep quality during the late luteal phase, while controls showed no significant differences. The researchers suggest that women with PMS may have underlying electroencephalogram trait markers.

Who's vCJD case definition should be revised

A new case of vCJD in Japan highlights the potential for misdiagnosis, as the patient's EEG showed a rare brainwave pattern characteristic. This discovery suggests revising the WHO definition to prevent missing cases.

Science of perception

A novel experiment revealed that experts in fine visual distinctions can process faces and other objects using the same neural networks, contradicting previous theories. This discovery has implications for our understanding of autism, national security, and expert recognition abilities.
