Study identifies autism gene which regulates dendrite development to slow down brain communication.

The development of neural connectivity is essential for brain function, and disruption of this process is associated with autism spectrum disorder (ASD).  Now, a study from researchers led by McMaster … Continue Reading Study identifies autism gene which regulates dendrite development to slow down brain communication.

Gene associated with intracranial aneurysm in French-Canadian population identified.

Intracranial aneurysms are a potentially life threatening neurological condition responsible for approximately 500,000 deaths worldwide per year, half of which occur in people less than 50 years of age.  They … Continue Reading Gene associated with intracranial aneurysm in French-Canadian population identified.

Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.

A significant milestone in the evolution of the mammalian brain is the emergence of the corpus callosum, which is exclusively present in placental mammals.  This commissure forms the largest axon … Continue Reading Neuroimaging shows that astrocytes are responsible for joining the 2 halves of the brain together.

Researchers identify the key instigator of neuron damage in sporadic and inherited ALS.

The onset of ALS, also known as Lou Gehrig’s disease, is marked by the gradual degradation and eventual death of neuronal axons, the slender projections on nerve cells which transmit … Continue Reading Researchers identify the key instigator of neuron damage in sporadic and inherited ALS.

Trauma’s inherited epigenetic fingerprint observed in children of Holocaust survivors.

The children of traumatized people have long been known to be at increased risk for post-traumatic stress disorder (PTSD). However, there are very few opportunities to examine biologic alterations in … Continue Reading Trauma’s inherited epigenetic fingerprint observed in children of Holocaust survivors.

Largest study of its kind sheds new light on the complex genetics of autism.

Genetic variation accounts for a major proportion of the liability to autism spectrum disorder (ASD).  Now, a study from led by researchers at UCLA shows that in families with multiple … Continue Reading Largest study of its kind sheds new light on the complex genetics of autism.

Researchers image the epigenetics of the human brain for the first time ever.

Epigenetic dysfunction is implicated in many neurological and psychiatric diseases, including Alzheimer’s disease and schizophrenia. Consequently, histone deacetylases (HDACs) are being aggressively pursued as therapeutic targets. However, a fundamental knowledge … Continue Reading Researchers image the epigenetics of the human brain for the first time ever.

Human study shows ‘aggressive drunk’ gene may protect carriers from obesity and associated risks.

It is known that genetics plays a role in obesity, with genes directly causing obesity in disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However, genes and behaviour may both … Continue Reading Human study shows ‘aggressive drunk’ gene may protect carriers from obesity and associated risks.
