You’re eating or drinking something frozen, like a snow cone, ice cream, or ice pops – probably a bit too eagerly – and you get one of those sudden-onset, painful headaches known as “brain freeze.” Man, does it hurt, but usually not for long, and it’s not harmful, according to an expert at UT Southwestern Medical Center.
Usando modelos humanos de “minicérebros” conhecidos como organoides, a Mayo Clinic e os cientistas da Universidade de Yale descobriram que as raízes do transtorno do espectro autista podem estar associadas com um desequilíbrio de neurônios específicos que exercem uma função crítica na forma como o cérebro se comunica e funciona.
Utilizando modelos de minicerebros humanos conocidos como organoides, científicos de Mayo Clinic y de la Universidad de Yale han descubierto que las raíces del trastorno del espectro autista pueden estar asociadas a un desequilibrio de neuronas específicas que desempeñan un papel fundamental en la forma en que el cerebro se comunica y funciona.
The Wits Neuroscience Research Lab (NeuRL) is working with an interdisciplinary team of researchers to build an immersive virtual reality laboratory. The team recently welcomed close collaborator Dr Harry Farmer, aSenior Lecturer in Psychology from the University of Greenwich, who delivered a hybrid seminar on how embodiment using virtual reality technologies can change previously held attitudes and beliefs.
Most of us who’ve reached middle age have noticed a slowing in memory and cognition, but scientists don’t have a clear picture of the molecular changes that take place in the brain to cause it. Now, a study in mice has determined that the most pronounced changes occur in the white matter, a type of nervous system tissue that’s integral to transmitting signals across the brain.
In trials, the antipsychotic drug brexpiprazole (Rexulti) failed to provide a clinically meaningful benefit and increased the risk of death. Yet the US Food and Drug Administration (FDA) has fast tracked its approval, making Rexulti the first antipsychotic for treating agitation in elderly patients with dementia.
Lead exposure has long been a known health risk, especially for young children. Research has found that even at low levels, chronic exposure to lead can cause damage to the brain and other organs and cause problems with cognitive and motor skills.
In patients with ALS, the motor dysfunction symptoms usually appear in one part of the body, such as the limbs, and then progress to others. This further suggests that degeneration starts in one type of motor neuron and, thereafter, propagates to other motor-related neurons.
Pioneering neuroscientist at the University of Chicago, Sliman Bensmaia helped develop prosthetic limbs that can restore a realistic sense of touch to amputees and paralyzed patients.
When choosing their behaviour in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious.

Only a small percentage of older adults who are in the early stages of Alzheimer’s disease meet the eligibility criteria to receive new monoclonal antibody treatments, drugs that target amyloid-ß plaques in the brain, an early sign of Alzheimer’s disease. The new research is published in the August 16, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. Clinical trial results for these drugs are only available in people in the early symptomatic stages of the disease, mild cognitive impairment or mild dementia due to Alzheimer’s disease.
