Cerebrospinal fluid autoantibodies target the brain in some COVID-19 patients

A study conducted by German researchers has shown that the neurological symptoms observed in some patients with coronavirus disease 2019 (COVID-19) may be caused by autoantibodies targeting the brain.

New nanoparticle-based artificial retina prosthesis restores vision in blind rats

An international team of scientists, of which the University of Granada (UGR) is a member, has developed a new nanoparticle-based artificial retina prosthesis that can be injected into the eye.

Study may lead to novel therapeutic targets in certain memory disorders

To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons' long, branching tentacles dock neurons together so they can talk.

Study provides new insights into the mystery of scent

The premiere of the movie Scent of Mystery in 1960 marked a singular event in the annals of cinema: the first, and last, motion picture debut "in glorious Smell-O-Vision."

Brain imaging can predict cognitive decline in Alzheimer’s disease

Researchers at Karolinska Institutet in Sweden have imaged tau protein in the brains of living patients with Alzheimer's disease.

Study identifies a promising way to delay the onset of Alzheimer's disease

Currently we are facing a dementia epidemic, estimations showing that by 2050 approximately 131 million people will be affected. Every 7 seconds a patient is diagnosed worldwide.

Novel method shows how cell membranes are damaged by 'Parkinson's protein'

In sufferers of Parkinson's disease, clumps of α-synuclein (alpha-synuclein), sometimes known as the 'Parkinson's protein', are found in the brain.

Study sheds light on selective neuronal vulnerability in Alzheimer’s disease

When Alzheimer's disease strikes, the entire brain doesn't crumble at once. Instead the mind unravels like grim clockwork, beginning with the telltale degradation of a group of brain cells in the entorhinal cortex.

Research reveals new genetic insights into how the brain folds

New research is helping unlock the mystery of how the brain folds as a baby develops in the womb - a process critical to healthy brain function.

'Mini-brains' can be infected by SARS-CoV-2 virus

A multidisciplinary team from two Johns Hopkins University institutions, including neurotoxicologists and virologists from the Bloomberg School of Public Health and infectious disease specialists from the school of medicine, has found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as "mini-brains" can be infected by the SARS-CoV-2 virus that causes COVID-19.

A semi-empirical model to reproduce the brain states from wakefulness to deep sleep

The human brain is a complex system comprising 1010 non-linear units (neurons) that interact in 1015 sites (synapses).

Researchers develop artificial liquid retinal prosthesis to counteract the effects of eye disorders

Researchers at IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) has led to the revolutionary development of an artificial liquid retinal prosthesis to counteract the effects of diseases such as retinitis pigmentosa and age-related macular degeneration that cause the progressive degeneration of photoreceptors of the retina, resulting in blindness.

Study uncovers algorithms and neural circuit mechanisms of escape responses

Ordered and variable animal behaviours emerge to explore and adapt to the environment. They are generally considered as the combination of a series of stereotyped motor primitives. However, how the nervous system shapes the dynamics of motor sequences remains to be solved.
