Targeting thalamic circuits could reverse Parkinson’s symptoms in mice

Parkinson's disease is best-known as a disorder of movement. Patients often experience tremors, loss of balance, and difficulty initiating movement. The disease also has lesser-known symptoms that are nonmotor, including depression.

Research finds increases in 'pandemic brain' after COVID-19 lockdowns

Chances are, the COVID-19 pandemic has affected your health — even if you have never been infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to new research from Harvard Medical School, the stress of isolation from lockdown and stay-at-home measures is making people sick.

Children in poverty have smaller volumes of certain subcortical brain regions, study finds

Children in poverty are more likely to have cognitive and behavioral difficulties than their better-off peers. Plenty of past research has looked into the physical effects of childhood poverty, or documented mental health disparities between socioeconomic classes.

Gene therapy shows promise in children with devastating genetic disorder

Children with a devastating genetic disorder characterized by severe motor disability and developmental delay have experienced sometimes dramatic improvements in a gene therapy trial launched at UCSF Benioff Children's Hospitals.

Study sheds light on how autism manifests in the brains of girls

New research has shed light on how autism-spectrum disorder (ASD) manifests in the brains of girls, prompting the scientists to warn that conclusions drawn from studies conducted primarily in boys should not be assumed to hold true for girls.

Neuroinvasiveness of SARS-CoV-2 shown by viral RNA and inflammation in the brain

A new study describes the results of a macaque study that showed the development of neurological features of inflammation, following infection by SARS-CoV-2.

Study provides detailed view of the brain’s ventral striatum activity involved in decision-making

Neuroscientists have provided clear visual evidence that a region of the human brain known as the ventral striatum kicks in during decision-making to weigh the costs versus the benefits of making a physical effort.

Parkinson's disease diagnosed after SARS-CoV-2

As the COVID-19 pandemic continues to spread, new and unusual chronic sequelae of the disease are cropping up in many medical practices. Now, a new case paper published in The Lancet in September 2020 describes a case of new-onset Parkinson's disease following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Anxiety and depression coexisting could cause physical changes to the brain

A new study from the researchers at the Australian National University shows that there may be physical changes in the brain volume among persons who have coexisting and anxiety and depressive disorders.

Cannabinoid 1 receptor expression displays sexually dimorphic pattern in the mouse brain

A major challenge in neuroscience lies in understanding how molecular and circuit differences in the brain synergistically contribute to sex differences in behavioral phenotypes. Sex differences in the brain may arise from the identity, distribution and relative abundance of cell types.
