Cognition and behavior: Autism brains have abnormal links

by  /  9 September 2011

The brains of boys with autism have a lower-than-normal rate of water diffusion across the inferior fronto-occipital fasciculus — a bundle of neurons that connects all four major lobes of the brain, according to a new study.

Molecular mechanisms: Some synaptic proteins travel in groups

by  /  28 June 2011

Soluble proteins band together into temporary complexes to travel to the tips of neurons, according to a study published 12 May in Neuron. The study provides the first evidence-based model for slow, directed neuronal transport, answering a long-standing question in the field.

Molecular mechanisms: Autism gene linked to mitochondria

by  /  22 March 2011

Disrupted-in-schizophrenia 1, or DISC1— a protein associated with both autism and schizophrenia — is involved in the transport of mitochondria, the power-houses of the cell, to their correct locations in neurons, according to a study published in February in Molecular Psychiatry.
